Investigation of the abnormal nasal aerodynamics and trigeminal functions among empty nose syndrome patients

The research report titled "Investigation of the abnormal nasal aerodynamics and trigeminal functions among empty nose syndrome patients" focuses on a condition known as Empty Nose Syndrome (ENS). This condition can occur after surgery on the nasal turbinates, which are structures inside the nose that help warm and humidify the air we breathe. When these turbinates are removed or reduced too much, some patients may feel like they cannot breathe properly, even though their nasal passages are open. This feeling can be very distressing and is often accompanied by other symptoms like dryness, a lack of air sensation, and a feeling of suffocation.

Key Findings

The study involved 27 patients diagnosed with ENS and compared their nasal airflow and sensations to 42 healthy individuals. The researchers used advanced technology called Computational Fluid Dynamics (CFD) to create detailed models of the nasal passages. This technology allows scientists to simulate how air moves through the nose and understand how changes in the structure of the nose can affect breathing.

One of the main findings was that ENS patients had a different airflow pattern compared to healthy individuals. Even though ENS patients had a higher total airflow, the way the air moved through their noses was not normal. The airflow was directed more towards the middle part of the nasal cavity, which is not where it should ideally go. This abnormal airflow can lead to less interaction between the air and the nasal tissues, which may explain some of the symptoms that ENS patients experience.

Understanding the Symptoms

The study also looked at how these airflow changes related to the symptoms reported by the patients. The researchers used a questionnaire called the Empty Nose Syndrome 6-item Questionnaire (ENS6Q) to assess the severity of symptoms. They found that patients who reported feeling suffocated or that their nose felt too open had more significant changes in their nasal airflow. This suggests that the way air moves through the nose is closely linked to how patients feel.

Lessons Learned

From this study, several important lessons can be drawn:

Nasal Structure Matters: The way the nasal passages are structured plays a crucial role in how air flows through them. If the structure is altered too much, it can lead to uncomfortable symptoms.

Airflow Patterns: Understanding airflow patterns in the nose can help explain why some patients feel symptoms even when their nasal passages are open. It’s not just about how much air can get in, but how that air moves.

Need for Better Diagnosis: The study highlights the need for better diagnostic tools and methods to assess ENS. Currently, diagnosis often relies on patients describing their symptoms, which can be subjective.

Conclusions

In conclusion, the research provides valuable insights into the relationship between nasal aerodynamics and the symptoms experienced by ENS patients. It emphasizes that abnormal airflow patterns can significantly impact how patients feel, even if their nasal passages appear clear. The findings suggest that future treatments for ENS should consider not just the physical opening of the nasal passages but also how air moves through them. This could lead to better management strategies for patients suffering from this challenging condition.

Overall, this study is a step forward in understanding ENS and could help improve the quality of life for those affected by it. By using advanced technology to study nasal airflow, researchers are paving the way for more effective treatments and a deeper understanding of how our bodies work.

Computational fluid dynamics and trigeminal sensory examinations of empty nose syndrome patients

The research report titled "Computational Fluid Dynamics and Trigeminal Sensory Examinations of Empty Nose Syndrome Patients" explores a condition known as Empty Nose Syndrome (ENS). This syndrome can occur after nasal surgeries, leading to a feeling of nasal obstruction despite having an open nasal airway. The study aims to understand how changes in airflow and sensory functions in the nose contribute to the symptoms of ENS.

What is Empty Nose Syndrome?

Empty Nose Syndrome is a condition that some people experience after undergoing surgeries on their nasal passages, such as turbinate reduction or septoplasty. Patients with ENS often feel like they cannot breathe properly, even though their nasal passages are physically open. This feeling can be very distressing and can significantly affect their quality of life.

The Purpose of the Study

The researchers wanted to investigate two main aspects of ENS:

Nasal Airflow: How air moves through the nasal passages of ENS patients compared to healthy individuals.

Sensory Function: How well the sensory nerves in the nose are working, particularly those that detect irritants and temperature changes.

Methods Used in the Study: To conduct the study, the researchers used several methods:

Questionnaires: Patients filled out surveys to report their symptoms and medical history. The questionnaires included the SNOT-22, NOSE score, and the ENS6Q, which help assess the severity of nasal symptoms.

CT Scans: Patients underwent CT scans to create detailed images of their nasal anatomy. This helped the researchers understand the physical structure of the nasal passages.

Computational Fluid Dynamics (CFD): This is a computer simulation technique that models how air flows through the nasal passages. By using CFD, the researchers could visualize and analyze airflow patterns in patients with ENS.

Sensory Testing: The researchers tested how well patients could detect certain smells and irritants, which is important for understanding the sensory function of the nose.

Key Findings

Airflow Patterns: The study found that patients with ENS had altered airflow patterns in their nasal passages. This means that the way air moves through their noses is different from that of healthy individuals. These changes in airflow can contribute to the sensation of nasal obstruction.

Sensory Dysfunction: The researchers observed that ENS patients often had impaired sensory functions. This means that their ability to detect smells and respond to irritants was not as effective as in healthy individuals. This sensory loss can make the experience of nasal obstruction feel even worse.

Impact of Surgery: The study highlighted that previous nasal surgeries could lead to these changes in airflow and sensory function. The researchers noted that the surgical impact, combined with pre-existing airflow patterns and sensory losses, plays a significant role in the development of ENS.

Conclusions Drawn from the Study

The researchers concluded that Empty Nose Syndrome is a complex condition influenced by multiple factors. They emphasized that:

Understanding Airflow and Sensory Function: It is crucial to understand how airflow and sensory functions are affected in ENS patients. This knowledge can help in developing better treatment strategies.

Future Research: The study suggests that combining CFD simulations with sensory testing could provide deeper insights into how surgeries impact nasal aerodynamics and sensory functions. This could lead to improved surgical techniques and better outcomes for patients.

What We Learned

From this study, we learned that Empty Nose Syndrome is not just about having an open nasal passage; it involves a complex interaction between airflow and sensory perception. The findings underscore the importance of considering both physical and sensory aspects when diagnosing and treating ENS. By understanding these factors, healthcare providers can work towards optimizing surgical outcomes and potentially preventing ENS in the future.

In summary, this research provides valuable insights into the challenges faced by ENS patients and highlights the need for a comprehensive approach to treatment that addresses both airflow and sensory function.

Functional Exercise Capacity and Perceived Exertion in Patients with Empty Nose Syndrome

The research study titled "Functional Exercise Capacity and Perceived Exertion in Patients with Empty Nose Syndrome" focuses on understanding how patients with Empty Nose Syndrome (ENS) experience physical activity and how their condition affects their ability to exercise.

What is Empty Nose Syndrome?

Empty Nose Syndrome is a condition that can occur after surgery on the nasal turbinates, which are structures inside the nose that help filter and humidify the air we breathe. Patients with ENS often feel a sensation of nasal obstruction despite having clear nasal passages. This can lead to various symptoms, including difficulty breathing, reduced sense of smell, and feelings of anxiety or discomfort.

Purpose of the Study

The main goal of the study was to assess how patients with ENS perform during physical activities and how they perceive their exertion or effort while exercising. The researchers wanted to see if there were differences in exercise capacity and perceived exertion between patients with mild-to-moderate symptoms and those with severe symptoms.

Key Findings

Participants: The study included 44 patients diagnosed with ENS. They were divided into two groups based on the severity of their symptoms, as measured by a questionnaire called the SNOT-25. One group had mild-to-moderate symptoms, while the other had severe symptoms.

Exercise Testing: The researchers used a 6-Minute Walk Test (6MWT) to measure how far participants could walk in six minutes. They also assessed perceived exertion using the Borg scale, which helps gauge how hard someone feels they are working during physical activity.

Results:

Patients showed significant improvements in their perceived exertion and oxygen levels after surgical treatment with submucosal Medpor implantation.

The study found that even small changes in the Borg scale scores could have important implications for patients, especially those with chronic lung conditions.

Interestingly, while the exercise capacity improved, traditional lung function tests did not show significant differences between the groups, suggesting that these tests might not fully capture the challenges faced by ENS patients during physical activity.

Understanding Perceived Exertion: The researchers noted that changes in Borg scale ratings do not always reflect a straightforward change in how hard patients feel they are working. This means that even if patients report feeling less breathless, it doesn't always mean their physical capabilities have improved in a linear way.

Conclusions

The study concluded that surgical intervention can lead to significant improvements in both exercise tolerance and respiratory efficiency for patients with ENS. It highlighted the importance of personalized exercise programs to help these patients manage their limitations and improve their quality of life. The researchers emphasized the need for further studies with larger groups to confirm these findings and explore additional measures of respiratory health.

Final Thoughts

Overall, this research sheds light on the challenges faced by patients with Empty Nose Syndrome and underscores the potential benefits of surgical treatment and tailored exercise programs. By understanding how ENS affects physical activity, healthcare providers can better support these patients in improving their overall health and well-being.

NASAL NITRIC OXIDE IN RELATION TO PSYCHIATRIC STATUS OF PATIENTS WITH EMPTY NOSE SYNDROME

Summary of the Study on Nasal Nitric Oxide (nNO) and Psychiatric Status in Empty Nose Syndrome (ENS) Patients

This study explored the relationship between nasal nitric oxide (nNO) levels and psychiatric health in patients with Empty Nose Syndrome (ENS). ENS is a rare but severe condition often caused by excessive removal of nasal tissue during surgery. Symptoms include a paradoxical sensation of nasal blockage despite an open airway, dryness, difficulty breathing, sleep issues, anxiety, and depression. The study focused on whether nNO, a molecule produced in the nasal passages that plays a role in immune defense and ciliary function, could be a useful indicator for monitoring the condition and its associated mental health impacts.

Background

Nasal nitric oxide (nNO) is typically used as a biomarker for various airway conditions. For example, nNO levels are known to increase after surgeries for sinusitis, reflecting improved sinus function. However, the role of nNO in ENS, particularly how it changes after surgical treatment and how it relates to psychiatric symptoms like anxiety and depression, had not been previously explored. This study aimed to fill that gap.

Methods

The study involved two groups of patients: 19 with ENS and 12 with chronic hypertrophic rhinitis (CHR), a condition characterized by the thickening of nasal tissue, who served as a comparison group. All patients underwent surgical treatments—submucosal implantation for ENS patients and turbinoplasty for CHR patients. The researchers measured nNO levels and assessed psychiatric symptoms using standardized questionnaires (SinoNasal Outcome Test-22, Beck Depression Inventory-II, and Beck Anxiety Inventory) before surgery and at 3, 6, and 12 months after surgery.

Key Findings

Lower nNO Levels in ENS Patients: Before surgery, ENS patients had significantly lower nNO levels compared to CHR patients. This finding was consistent with the fact that ENS is associated with disrupted nasal physiology.

Post-Surgery Increase in nNO for ENS Patients: After undergoing submucosal implantation surgery, ENS patients showed a significant increase in nNO levels by the third month, which then plateaued and remained stable at 6 and 12 months. This suggests that the surgery helped restore some of the nasal functions in these patients.

Improvement in Psychiatric Symptoms: Alongside the increase in nNO levels, ENS patients experienced significant reductions in symptoms of depression and anxiety, as measured by the Beck Depression Inventory-II and Beck Anxiety Inventory. These improvements were not observed in CHR patients, who had normal psychiatric scores before surgery.

Correlation Between nNO and Psychiatric Health: The study found a significant correlation between the increase in nNO levels and the improvement in psychiatric symptoms in ENS patients. This suggests that nNO could potentially be used to monitor not only the physical recovery of ENS patients but also their mental health.

Different Responses in CHR Patients: CHR patients, who had higher nNO levels to begin with, did not show significant changes in nNO levels after their surgery, and their psychiatric symptoms remained stable, indicating a different mechanism of disease and recovery compared to ENS.

Conclusions

The study concluded that nNO levels are significantly lower in ENS patients compared to those with CHR, and that these levels increase following surgical intervention, paralleling improvements in anxiety and depression. This suggests that nNO could serve as an important biomarker for both the physical and psychological health of ENS patients. The findings offer new insights into the complex relationship between nasal physiology and mental health in ENS, highlighting the potential of nNO as a tool for monitoring patient outcomes post-surgery. Future research could explore this further and determine whether nNO measurements could become a standard part of ENS treatment protocols.

Evaluation of Depression and Anxiety in Empty Nose Syndrome After Surgical Treatment

The research report titled "Evaluation of Depression and Anxiety in Empty Nose Syndrome" investigates the psychological effects of Empty Nose Syndrome (ENS) and how surgical treatment can improve the mental health of patients suffering from this condition. ENS is a condition that can occur after nasal surgery, leading to a feeling of excessive nasal emptiness, which can cause various physical and psychological symptoms.

Summary of the Study

Background: ENS is not just about physical changes in the nasal cavity; it also involves psychological aspects. Patients often report feelings of anxiety and depression, which can significantly affect their quality of life. The study aimed to evaluate these psychological symptoms and see if surgical intervention could help.

Methods: The researchers used two main psychological assessment tools: the Beck Depression Inventory-II (BDI-II) and the Beck Anxiety Inventory (BAI). These tools help measure the levels of depression and anxiety in patients. The study involved patients who underwent a specific surgical procedure called endonasal submucosal implantation, where a material (Medpor) or bone grafts were placed in the nasal cavity to improve airflow and reduce symptoms.

Surgical Procedure: The surgery was performed under local anesthesia. The surgeons created a pocket in the nasal wall to insert the implant, aiming to restore a more normal nasal structure and function. The goal was to alleviate the symptoms of ENS and improve the patients' overall well-being.

Findings: After the surgery, patients showed significant improvements in both their depression and anxiety scores. The results indicated that many patients felt less anxious and depressed after the procedure. For example, specific symptoms like feelings of fear, nervousness, and difficulty relaxing were notably reduced.

Conclusions: The study concluded that surgical treatment for ENS not only helps with physical symptoms but also leads to significant improvements in psychological health. This suggests that addressing the physical aspects of ENS can have a positive ripple effect on mental health, providing a better quality of life for patients.

Key Takeaways

ENS is a complex condition that affects both the body and mind. Surgical intervention can effectively reduce symptoms of depression and anxiety in ENS patients. The study highlights the importance of considering psychological health when treating patients with ENS. Overall, this research emphasizes the need for a holistic approach to treating ENS, where both physical and psychological aspects are addressed to improve patient outcomes.

Användning av blodplättsrikt fibrin (PRF) tillsammans med finfördelat brosk vid behandling av Empty Nose Syndrome.

Empty Nose Syndrome (ENS) är ett tillstånd som kan uppstå hos patienter som genomgått operationer i näsan där för mycket av näsmusslan tagits bort. Detta syndrom leder till allvarliga symtom som torr näsa, smärtsam andning genom näsan, paradoxal nästäppa, skorpbildning och sömnproblem. Målet med kirurgisk behandling är att återställa volymen av näsmusslan för att återfå normalt motstånd i näsan. En metod som används är endonasal mikroplastik, där broskimplantat placeras på näsans sidovägg för att skapa en ny näsmussla. I denna artikel presenteras två fall där patienter med ENS behandlades med endonasal mikroplastik, där man använde en platta av blodrikt fibrin (PRF) tillsammans med finfördelat brosk. PRF-plattan hjälpte till att återbilda näsmusslan effektivt. Detta kroppsegna material visade sig vara lämpligt för att behandla ENS.

Introduktion

Empty Nose Syndrome (ENS) är en sällsynt och försvagande sjukdom som kännetecknas av torr näsa, smärtsam andning genom näsan, paradoxal nästäppa, skorpbildning och sömnproblem. ENS beskrevs första gången 1994 av Eugene Kern och är en sjukdom som orsakas av att för mycket av näsmusslan har tagits bort under en operation i näsan. Förutom fysiska symtom kan patienter med ENS uppleva ångest och depression, vilket ibland kan leda till självmordstankar. Det är svårt att diagnostisera ENS eftersom inte alla patienter upplever dessa symtom efter en radikal operation av näsmusslan. Diagnos ställs ofta baserat på patientens beskrivning av symtomen. Ett nytt verktyg, "Empty Nose Syndrome 6-item Questionnaire" (ENS6Q), har utvecklats för att hjälpa till att identifiera patienter som misstänks ha ENS.

Syftet med kirurgisk behandling för ENS är att återuppbygga näsmotståndet genom att smalna av luftvägen med ett implantat. Detta implantat placeras i en submukosal ficka i näsväggen, vilket leder till återbildning av nässlemhinnan, bättre fuktbevarande i näshålan och en ökning av luftflödet genom näsan. För detta ändamål har olika material använts, såsom injicerbara fyllmedel, syntetiska implantat, allograftmaterial och kroppsegna material som brosk.

Ny forskning inom vävnadsteknik och regenerativ medicin har fokuserat på att utveckla kostnadseffektiva biomaterial för att reglera inflammation och förbättra läkningsprocesser. PRF (blodrikt fibrin) är ett kroppseget biokemiskt och biophysikaliskt produkt som levererar tillväxtfaktorer, cytokiner och immunceller för att stödja immunmodulation och vävnadsläkning. Användningen av PRF har nyligen blivit en lovande strategi för att förbättra broskets återbildningsprocess. Detta är den första studien som undersöker den kliniska tillämpningen av PRF och finfördelat brosk för att återställa den saknade näsmusslan.

Kirurgisk teknik

Operationerna utfördes under narkos på ett operationsrum. Brosk hämtades från patientens öra och finfördelades för att skapa en klibbig broskmassa. Ett blodprov togs och centrifugerades för att separera PRF, som sedan blandades med det finfördelade brosket. Efter att blandningen hade stabiliserats placerades den i en ficka under nässlemhinnan. Såret täcktes med Hemopatch® för att hålla broskimplantatet på plats.

Fallbeskrivningar

Fall 1: En 32-årig man som hade genomgått en näsoperation fem år tidigare, klagade på ihållande andningsproblem, nästäppa, torrhet i munnen, dålig sömn och huvudvärk. Efter operationen kände han att hans andning förbättrades avsevärt, och andra symtom som huvudvärk och torrhet försvann. Ett år efter operationen fanns broskimplantatet fortfarande kvar på sin plats.

Fall 2: En 55-årig man som hade genomgått flera operationer för sju år sedan upplevde ansiktsvärk, huvudvärk, kvävningskänslor och oro. Efter en ny operation rapporterade han förbättrad sömn, mer energi och minskad huvudvärk. Broskimplantatet var fortfarande på plats efter ett år.

Diskussion

Att behandla ENS är en utmaning, och det är svårt att lindra alla patientens symtom. Målet med medicinsk behandling är att fukta näshålan genom sköljning och använda fuktgivande salvor. Men kirurgiska behandlingar som återställer näsmusslans volym kan ge bättre resultat. PRF har visat sig vara ett lovande material för att hjälpa till med broskåterbildning, och det har använts framgångsrikt i de presenterade fallen.

Slutsats

Resultaten i denna studie tyder på att kombinationen av PRF och finfördelat brosk är lämplig för behandling av ENS genom endonasal mikroplastik. Ytterligare studier behövs för att utveckla mer effektiva protokoll och jämföra effektiviteten av denna metod med andra behandlingar.

The Degree of Stress in Patients With Empty Nose Syndrome, Compared With Chronic Rhinosinusitis and Allergic Rhinitis

The research titled "The Degree of Stress in Patients With Empty Nose Syndrome, Compared With Chronic Rhinosinusitis and Allergic Rhinitis" aimed to investigate the psychological burden, specifically the prevalence and severity of depression, in patients diagnosed with Empty Nose Syndrome (ENS) compared to those with chronic rhinosinusitis (CRS) and allergic rhinitis (AR).

Study Overview

The study involved a cohort of patients diagnosed with ENS at Kosin University Hospital between January 2015 and May 2017. The diagnosis of ENS was based on a history of previous nasal surgery, subjective symptoms such as excessive nasal crusting, paradoxical nasal congestion, and a positive cotton test. The researchers excluded patients with a prior diagnosis of depression to focus on the psychological impact of ENS specifically.

To assess depression levels, the Beck Depression Inventory (BDI) was utilized, which categorizes depression into normal, mild, moderate, and severe based on total scores. Additionally, the Sino Nasal Outcome Test-22 (SNOT-22) was employed to evaluate the severity of nasal symptoms.

Results

The findings revealed that patients with ENS exhibited a significantly higher prevalence of depression compared to those with CRS and AR. Specifically, the study reported that 71% of patients with ENS experienced some degree of depression, with 13% showing mild depression, 33% moderate depression, and 25% severe depression. In contrast, the rates of depression in the CRS groups were lower, with 19% in CRS with polyps and 15% in CRS without polyps.

The study also highlighted that while the BDI scores were higher in the ENS group, there was no statistically significant correlation between the BDI scores and the SNOT-22 scores. This suggests that the severity of nasal symptoms does not directly correlate with the level of depression, indicating that other factors may contribute to the psychological distress experienced by ENS patients.

Conclusions

The research concluded that the degree and severity of depression in patients with ENS are notably higher than in those with other sinonasal diseases. This underscores the importance of recognizing and addressing the psychological aspects of ENS, as mental health issues may significantly impact the quality of life for these patients. The authors emphasized that the psychological burden associated with ENS should not be overlooked, advocating for a comprehensive approach to treatment that includes mental health assessments.

Overall, the study provided valuable insights into the mental health challenges faced by patients with ENS, highlighting the need for further research and consideration of psychological support in the management of this condition.

Identifying Residual Psychological Symptoms after Nasal Reconstruction Surgery in Patients with Empty Nose Syndrome

The study titled "Identifying Residual Psychological Symptoms after Nasal Reconstruction Surgery in Patients with Empty Nose Syndrome" investigates the psychological impact of nasal reconstruction surgery on patients diagnosed with Empty Nose Syndrome (ENS). ENS is a condition that can occur after nasal surgeries, leading to a range of debilitating symptoms, including a sensation of nasal obstruction despite having a patent airway, which can significantly affect patients' quality of life.

The researchers aimed to evaluate the psychological symptoms experienced by ENS patients both preoperatively and postoperatively, utilizing validated assessment tools such as the SNOT-25 (Sinus and Nasal Quality of Life Survey), ENS6Q (Empty Nose Syndrome 6-Questionnaire), BDI-II (Beck Depression Inventory-II), and BAI (Beck Anxiety Inventory). The study included 40 patients with ENS and a control group of 40 age- and sex-matched individuals.

Results indicated that both the BDI-II and BAI scores significantly improved six months and one year after surgery compared to preoperative scores. However, the postoperative scores for ENS patients remained significantly higher than those of the control group, suggesting that while surgery alleviated some psychological symptoms, residual symptoms persisted. Notably, a BDI-II score greater than 28.5 was identified as the optimal cutoff for predicting postoperative residual psychological symptoms.

The study concluded that a comprehensive psychological evaluation is crucial for ENS patients undergoing surgery. It highlighted the importance of recognizing individuals at risk for postoperative psychological distress and suggested that a multimodal approach, including both surgical and psychiatric interventions, is essential for achieving optimal therapeutic outcomes. This research underscores the significant psychological burden faced by ENS patients and the need for ongoing support even after surgical interventions.

What drives depression in empty nose syndrome? A Sinonasal Outcome Test-25 subdomain analysis

The study titled "What Drives Depression in Empty Nose Syndrome? A Sinonasal Outcome Test-25 Subdomain Analysis" investigates the relationship between disease-specific quality of life impairments and the severity of anxiety and depression in patients with Empty Nose Syndrome (ENS). The primary goal of the research was to determine how various aspects of ENS impact psychological distress and to evaluate how these associations change following surgical intervention.

Study Design and Methods

The study included 68 patients diagnosed with ENS, a condition characterized by paradoxical nasal obstruction following excessive surgical removal of nasal tissues. To address ENS symptoms, patients underwent submucosal Medpor implantation, a surgical procedure aimed at improving nasal airflow and function. The impact of ENS on patients' quality of life and psychological status was assessed using the Sinonasal Outcome Test-25 (SNOT-25), the Beck Depression Inventory-II (BDI-II), and the Beck Anxiety Inventory (BAI). Evaluations were conducted one day before surgery and again six months after the procedure.

Results

The study found significant correlations between the severity of anxiety and depression (as measured by BDI-II and BAI scores) and various domains of the SNOT-25, which includes measures of total score, ear/facial symptoms, psychological dysfunction, sleep dysfunction, and empty nose symptoms. Improvements in ENS symptoms were associated with reductions in depression and anxiety. Notably, changes in BDI-II scores post-operatively were correlated with improvements in the SNOT-25’s total score, as well as in the sleep dysfunction and empty nose symptoms domains.

Furthermore, the study identified specific SNOT-25 scores as predictors of moderate-to-severe depression. Scores exceeding 60 on the total SNOT-25, above 18 in the sleep dysfunction domain, and greater than 14 in the empty nose symptoms domain were strong indicators of significant depressive symptoms.

Conclusions

The findings indicate that ENS symptoms significantly affect psychological well-being, and specific quality of life impairments can predict moderate-to-severe depression. The study highlights the importance of addressing both physical and psychological aspects of ENS. Improvements in ENS symptoms, particularly related to sleep dysfunction and empty nose symptoms, were associated with reductions in depression and anxiety. This suggests that targeted management of these symptoms could substantially reduce the psychological burden experienced by ENS patients.

In summary, the research provides important insights into the relationship between ENS and mental health, demonstrating that effective treatment of ENS symptoms can lead to significant improvements in psychological outcomes. The study underscores the need for comprehensive treatment approaches that address both the physical and psychological dimensions of ENS to enhance overall patient well-being.

IMPACT OF SLEEP DYSFUNCTION ON PSYCHOLOGICAL BURDEN IN PATIENTS WITH EMPTY NOSE SYNDROME

The study titled "Impact of Sleep Dysfunction on Psychological Burden in Patients with Empty Nose Syndrome" aimed to explore the relationship between sleep disturbances and psychological symptoms in patients diagnosed with Empty Nose Syndrome (ENS). The research involved 46 patients who had undergone nasal reconstruction surgery using submucosal Medpor implantation between 2016 and 2021.

Study Design and Methods

Patients included in the study were diagnosed with ENS, characterized by paradoxical nasal obstruction following inferior turbinate surgery. The diagnosis was confirmed through symptoms, endoscopic findings, and a positive cotton test. Patients with other sinonasal conditions or psychiatric disorders were excluded. The study utilized the Empty Nose Syndrome 6-item Questionnaire (ENS6Q), Beck Depression Inventory-II (BDI-II), Beck Anxiety Inventory (BAI), Epworth Sleepiness Scale (EpSS), and Modified Sleep Quality Index (MSQI) to evaluate sleep quality, psychological burden, and symptom severity before and 6 months after surgery.

Results

The study revealed significant improvements in ENS symptoms, sleep quality, and psychological distress following surgery. Scores on the ENS6Q, EpSS, MSQI, BDI-II, and BAI all showed significant reductions post-operatively. Specifically, the ENS6Q score decreased from 16.7 to 7.5, EpSS from 11.1 to 7.5, MSQI from 27.9 to 16.9, BDI-II from 20.0 to 7.3, and BAI from 20.1 to 9.7, with all changes being statistically significant (p < 0.001).

The study also identified a strong association between sleep dysfunction and psychological symptoms. Notably, 41.3% of patients experienced moderate-to-severe depression preoperatively. The study used receiver operating characteristic (ROC) curves to determine the sensitivity and specificity of the EpSS and MSQI in detecting moderate-to-severe depression. The ROC analysis revealed that the EpSS and MSQI were effective in identifying depression, with significant areas under the curve (AUC) indicating their utility in clinical settings.

Conclusions

The research underscored the significant impact of sleep dysfunction on psychological symptoms in ENS patients. The findings highlight the importance of addressing sleep issues as part of the management plan for ENS. Improved sleep quality post-surgery was associated with reduced psychological burden, indicating that effective management of sleep disturbances could enhance overall mental health outcomes. The study advocates for integrating sleep evaluation into the care of ENS patients to address and mitigate associated psychological distress.

Overall, this study provides valuable insights into the interplay between sleep and psychological health in ENS patients and supports the need for comprehensive approaches to managing both sleep dysfunction and psychological symptoms in this population.
