Sleep Subdomain of the Sinonasal Outcome Test as a Potential Screening Tool for Sleep Apnea in Chronic Rhinosinusitis.

OBJECTIVES: Approximately 20% of patients with chronic rhinosinusitis (CRS) have comorbid obstructive sleep apnea (OSA). Patients with undiagnosed OSA are at high risk for perioperative complications. The Sinonasal Outcomes Test (SNOT-22) Questionnaire is commonly administered to CRS patients, whereas OSA screening tools are less routinely employed. This study compared SNOT-22 sleep subdomain (Sleep-SNOT) scores among non-OSA CRS versus OSA-CRS patients undergoing ESS, and assessed sensitivity, specificity, and diagnostic accuracy of the Sleep-SNOT for OSA screening. METHODS: Retrospective review of patients that underwent endoscopic sinus surgery (ESS) for CRS from 2012 to 2021. Patients either carried a reported OSA diagnosis and completed the SNOT-22, or had undocumented OSA status and completed both STOP-BANG and SNOT-22. Demographics, questionnaire scores, and OSA status were collected. A receiver operating characteristic (ROC) curve assessed cutoff scores, sensitivity, and specificity of the Sleep-SNOT for OSA screening. RESULTS: Of 600 patients reviewed, 109 were included. 41% had comorbid OSA. OSA patients had a higher BMI (32.1 ± 7.7 vs. 28.35 ± 6.7 kg/m2 ; p = 0.02), Sleep-SNOT (21.96 ± 12.1 vs. 16.8 ± 11.2; p = 0.021) and STOP-BANG (3.1 ± 1.44 vs. 2.06 ± 1.27; p = 0.038) scores. A Sleep-SNOT score of 17.5 had a sensitivity of 68.9%, specificity of 55.7%, and diagnostic accuracy of 63% for OSA detection (p = 0.022). CONCLUSIONS: Sleep-SNOT scores are greater for CRS-OSA patients. The Sleep-SNOT ROC curve demonstrates a high sensitivity, specificity, and accuracy for OSA screening in CRS patients. A Sleep-SNOT score of ≥17.5 should prompt further OSA evaluation. The Sleep-SNOT may be considered as a surrogate OSA screening tool when other validated tools are not employed.

Volumetric Analysis of the Sinus and Orbit in Silent Sinus Syndrome After Endoscopic Sinus Surgery.

OBJECTIVE: The term "silent sinus syndrome" (SSS) describes spontaneous enophthalmos secondary to subclinical maxillary sinus atelectasis. Debate remains on whether treatment with endoscopic maxillary antrostomy alone is adequate in reversing atelectasis and globe displacement. This study aims to determine the degree of volume change of the diseased sinus and orbit as well as the change in orbital height in patients treated with endoscopic antrostomy without orbital floor augmentation. STUDY DESIGN: Retrospective review with image analysis. SETTING: Single tertiary care institution. METHODS: Three-dimensional (3D) analysis of computed tomographic imaging data was performed using 3D Slicer. 3D models of the maxillary sinus and orbit of the diseased and normal sides were created, and volume measurements were calculated using the segmentation program. RESULTS: Thirteen patients with SSS who underwent endoscopic sinus surgery (ESS) and had follow-up computed tomographic imaging were analyzed. After endoscopic antrostomy, the mean volume of the diseased maxillary sinus significantly increased by 9.82%, from 6.37 to 7.00 cm3 (p = .0302). There was no significant change in mean orbital volume; however, the mean orbital height decreased by 5.67%, from 38.09 to 35.93 mm from pretreatment to posttreatment samples (p = .0101). All patients had resolution of clinical or radiographic enophthalmos and orbital displacement with ESS alone. CONCLUSION: Endoscopic maxillary antrostomy alone in the treatment of SSS significantly increased maxillary sinus volume and decreased diseased orbital height. These changes were associated with clinical and radiographic improvement in globe displacement. These findings support performing ESS alone, reserving orbital augmentation for patients who do not exhibit adequate clinical improvement.

Orbital resection by intranasal technique (ORBIT): A new classification system for reporting endoscopically resectable primary benign orbital tumors.

BACKGROUND: The Cavernous Hemangioma Exclusively Endonasal Resection (CHEER) staging system has become the gold standard for outcomes reporting in endoscopic orbital surgery for orbital cavernous hemangiomas (OCHs). A recent systematic review demonstrated similar outcomes between OCHs and other primary benign orbital tumors (PBOTs). Therefore, we hypothesized that a simplified and more comprehensive classification system could be developed to predict surgical outcomes of other PBOTs. METHODS: Patient and tumor characteristics as well as surgical outcomes from 11 international centers were recorded. All tumors were retrospectively assigned an Orbital Resection by Intranasal Technique (ORBIT) class and stratified based on surgical approach as either exclusively endoscopic or combined (endoscopic and open). Outcomes based on approach were compared using chi-squared or Fisher's exact tests. The Cochrane-Armitage test for trend was used to analyze outcomes by class. RESULTS: Findings from 110 PBOTs from 110 patients (age 49.0 ± 15.0 years, 51.9% female) were included in the analysis. Higher ORBIT class was associated with a lower likelihood of gross total resection (GTR). GTR was more likely to be achieved when an exclusively endoscopic approach was utilized (p < 0.05). Tumors resected using a combined approach tended to be larger, to present with diplopia, and to have an immediate postoperative cranial nerve palsy (p < 0.05). CONCLUSION: Endoscopic treatment of PBOTs is an effective approach, with favorable short-term and long-term postoperative outcomes as well as low rate of adverse events. The ORBIT classification system is an anatomic-based framework that effectively facilitates high-quality outcomes reporting for all PBOTs.

Effect of p16 Status on Survival Outcomes in Sinonasal Squamous Cell Carcinoma.

OBJECTIVE: Evaluate the effect of p16 status on disease-free survival (DFS) and overall survival (OS) in patients with sinonasal squamous cell carcinoma (SCC) undergoing treatment with curative intent; and to assess how p16 status may affect patterns of recurrence. STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary medical center. METHODS: Patients with sinonasal SCC treated with curative intent from 2012 to 2018 were identified. Independent variable of interest was p16 status, which was assessed using immunohistochemistry (IHC) with a 70% staining cutoff for positivity. Kaplan Meier survival curve was plotted to assess correlation between p16 status and DFS and OS. Association between recurrence patterns and p16 status was conducted using chi square and fisher's exact tests. Multivariable Cox proportional hazard analysis was conducted to assess association between independent variables and DFS. RESULTS: Fifty patients with sinonasal SCC met inclusion criteria. Patients were p16 positive in 28/50 (56%) of cases. Kaplan Meier survival curve revealed no statistically significant association between p16 status and DFS or OS survival (P = .780, P = .474). There was no difference in recurrence patterns in patients with p16 positive versus negative tumors. CONCLUSION: p16 status did not have prognostic value on DFS and OS in our cohort of patients with sinonasal SCC undergoing treatment with curative intent. There was no difference in recurrence patterns between the 2 populations. Based on the results of this study, p16 status should not impact counseling of patients as it relates to their prognosis from SNM.

Perioperative Outcomes of a Hydrocortisone Protocol after Endonasal Surgery for Pituitary Adenoma Resection.

Introduction In pituitary adenomas (PAs), the use of postoperative steroid supplementation remains controversial, as it reduces peritumoral edema and sinonasal complaints but disrupts the detection of adrenal insufficiency (AI). It is unclear whether postoperative cortisol supplementation has a measurable effect on improving outcomes in patients with pituitary adenoma undergoing endoscopic transsphenoidal surgery (ETS). The objective of the study was to evaluate a postoperative steroid treatment protocol on various surgical outcomes in patients with PA undergoing ETS. Methods A retrospective cohort study was performed for patients undergoing ETS from 2005 to 2020 for PA at a single tertiary academic center. Patients were divided into two groups: those managed by a routine postoperative glucocorticoid supplementation protocol (steroid protocol) and those who received supplementation based on postoperative cortisol laboratory assessment (steroid sparing protocol). Management was otherwise the same between groups. Evaluation of length of stay (LOS), sinonasal outcomes, 30-day readmission, and perioperative complications, including AI, were performed. Results Among 535 patients, 21% ( n = 111) received postoperative steroids, while the remainder ( n = 424) did not. There were no differences in mean LOS (3 vs. 3 days, p = 0.72), sinonasal complaints (27 vs. 19%, p = 0.12), 30-day readmission (5% vs. 5%, p = 0.44), and perioperative complications (5 vs. 5%, p = 0.79) between both the groups. A multivariate model supported that both groups were comparable in predicting LOS, 30-day readmission, and complications. No reduction in readmission for AI was seen. Conclusion Routine administration of postoperative glucocorticoids did not significantly improve patient outcomes in patients with PA who underwent ETS.

Surgical Outcomes of Endoscopic Transsphenoidal Pituitary Adenoma Resection in Elderly Versus Younger Patients.

Introduction Pituitary adenomas (PAs) are one of the most common types of intracranial neoplasm with increased incidence in elderly patients. The outcomes of endoscopic transsphenoidal surgery (ETS) specifically on elderly patients remain unclear. Methods We performed a retrospective cohort study to compare elderly patients (age ≥65 years) with nonelderly patients (age <65 years) who underwent ETS for PA from January 2005 to December 2020. Surgical outcomes, including extent of resection, complication profile, length of stay, and endocrinopathy rates, were compared between elderly and nonelderly patients. Results A total of 690 patients were included, with 197 (29%) being elderly patients. Elderly patients showed higher rates of hypertension ( p < 0.05), myocardial infarction ( p < 0.01), and atrial fibrillation ( p = 0.01) but not other comorbidities. Elderly patients also had more frequent optic nerve involvement (72 vs. 61% of cases, p = 0.01). Tumor characteristics and other patient variables were otherwise similar between younger and elderly patients. Postoperative cerebrospinal fluid (CSF) leaks (2 vs. 2%, p = 0.8), 30-day readmission, reoperation, postoperative complications, and postoperative endocrinopathies were similar between younger and older patients. Subdividing patients into age <65, 65 to 79, and >80 years also did not demonstrate a worsening of surgical outcomes with age. Conclusion For well-selected elderly patients in experienced endoscopic skull base centers, good surgical outcomes similarly to younger patients may be achieved.

A Single Layer Synthetic Dural Substitute Inlay is an Effective Sellar Reconstruction Technique in Endoscopic Transsphenoidal Pituitary Surgery.

Objectives A variety of endonasal sellar repair techniques have been described; many are complex, multilayered, and carry potential morbidity. We propose an effective, technically simple single-layer repair for select sellar defects, including those with an intraoperative cerebrospinal fluid (CSF) leak. Our technique utilizes only a synthetic dural substitute inlay and dural sealant glue without packing or lumbar drainage. Design This is a retrospective review-based study. Setting This study was conducted at tertiary care center. Participants Patients who underwent endoscopic transsphenoidal surgery for pituitary adenoma and sellar reconstruction with the aforementioned inlay technique. Patients were selected for this technique if they had an identified intraoperative CSF leak, a patulous diaphragm (expanded and thinned diaphragma sella), or a comorbidity excluding them from a simpler onlay only reconstruction. Outcome Measures Postoperative CSF leak and sinonasal morbidity included in the study. Results A total of 409 subjects were identified; 368 were initial resections. Gross total resection of the pituitary adenoma was achieved in 356 (87.0%) cases. Average tumor size was 2.6 ± 1.1 cm. Average tumor volume was 10.8 ± 12.1 cm 3 . There were 135 intraoperative CSF leaks and 196 patulous diaphragms. There were five postoperative CSF leaks (1.2%), all of which occurred in the first half of our series. Pre- and postoperative sino-nasal outcomes test-22 scores were 19.2 ± 18.2 and 18.8 ± 21.3 ( p = 0.492), respectively. Conclusion A synthetic dural substitute inlay and dural sealant glue is an excellent single-layer repair for sellar defects, even those with an intraoperative CSF leak. This technique is highly effective in preventing postoperative CSF leaks and does not utilize packing or lumbar drainage. It also avoids the potential cost and morbidity associated with more complex and multilayered closures.

An algorithm for sellar reconstruction following endoscopic transsphenoidal surgery for pituitary adenoma: A review of 582 cases.

BACKGROUND: Several sellar reconstruction algorithms stratify patients based on risk of postoperative cerebrospinal fluid (CSF) leak. Many proposed algorithms employ techniques that are overly complex and confer morbidity. We review our experience with sellar reconstruction following transsphenoidal pituitary surgery and propose a highly effective, yet simple and low morbidity, algorithm. METHODS: A retrospective review of 582 patients who underwent transsphenoidal surgery for pituitary adenoma by a single neurosurgeon between 2005 and 2020 was performed. Patients without an intraoperative CSF leak and without a patulous diaphragm were repaired with an oxidized cellulose onlay (group 1). Patients with a low-flow intraoperative CSF leak or a patulous diaphragm were repaired with a synthetic dural substitute inlay (group 2). Patients with a persistent leak around the inlay repair or a high-flow leak were reconstructed with a synthetic dural substitute inlay and a nasoseptal flap onlay (group 3). RESULTS: There was an overall leak rate of 1.5% (9/582) to 1.0% (2/197) in group 1, 1.7% (6/347) in group 2, and 2.6% (1/38) in group 3. Group 3 had the highest rate of postoperative morbidity, including sinusitis (23.7% vs. 8.6% and 15.0% in groups 1 and 2, p = 0.018) and crusting (42.1% vs. 4.6% and 6.3% in groups 1 and 2, p < 0.001). All techniques healed equally well radiographically. CONCLUSION: The proposed algorithm for sellar reconstruction is highly effective and minimizes complexity and morbidity, primarily utilizing single-layer reconstructions without the addition of packing material or lumbar drainage.

Evaluation of early postoperative day 1 discharge after endoscopic endonasal pituitary adenoma resection.

OBJECTIVE: While multiple studies have evaluated the length of stay after endonasal transsphenoidal surgery (ETS) for pituitary adenoma, the potential for early discharge on postoperative day 1 (POD 1) remains unclear. The authors compared patients discharged on POD 1 with patients discharged on POD > 1 to better characterize factors that facilitate early discharge after ETS. METHODS: A retrospective chart review was performed for patients undergoing ETS for pituitary adenoma at a single tertiary care academic center from February 2005 to February 2020. Discharge on POD 1 was defined as a discharge within 24 hours of surgery. RESULTS: A total of 726 patients (mean age 55 years, 52% male) were identified, of whom 178 (24.5%) patients were discharged on POD 1. These patients were more likely to have pituitary incidentaloma (p = 0.001), require dural substitutes and DuraSeal (p = 0.0001), have fewer intraoperative CSF leaks (p = 0.02), and have lower postoperative complication rates (p = 0.006) compared with patients discharged on POD > 1. POD 1 patients also showed higher rates of macroadenomas (96.1% vs 91.4%, p = 0.03) and lower rates of functional tumors (p = 0.02). POD > 1 patients were more likely to have readmission within 30 days (p = 0.002), readmission after 30 days (p = 0.0001), nasal synechiae on follow-up (p = 0.003), diabetes insipidus (DI; 1.7% vs 9.8%, p = 0.0001), postoperative hypocortisolism (21.8% vs 12.1%, p = 0.01), and postoperative steroid usage (44.6% vs 59.7%, p = 0.003). The number of patients discharged on POD 1 significantly increased during each subsequent time epoch: 2005-2010, 2011-2015, and 2016-2020 (p = 0.0001). On multivariate analysis, DI (OR 7.02, 95% CI 2.01-24.57; p = 0.002) and intraoperative leak (OR 2.02, 95% CI 1.25-3.28; p = 0.004) were associated with increased risk for POD > 1 discharge, while operation epoch (OR 0.46, 95% CI 0.3-0.71; p = 0.0001) was associated with POD 1 discharge. CONCLUSIONS: This study demonstrates that discharge on POD 1 after ETS for pituitary adenomas was safe and feasible and without increased risk of 30-day readmission. On multivariate analysis, surgical epoch was associated with decreased risk of prolonged length of stay, while factors associated with increased risk of prolonged length of stay included DI and intraoperative CSF leak. These findings may help in selecting patients who are deemed reasonable for safe, early discharge after pituitary adenoma resection.

A Simple Onlay Sellar Reconstruction Does Not Increase the Risk of Postoperative Cerebrospinal Fluid Leak in Well-Selected Patients.

Objective A variety of endonasal sellar repair techniques have been described; many of which are complex, expensive, and carry potential morbidity but are felt to be necessary to prevent postoperative cerebrospinal fluid (CSF) leaks. We propose an effective, technically simple repair for select sellar defects utilizing an onlay of regenerated oxidized cellulose. Design Retrospective review of patients from a single neurosurgeon who underwent endoscopic transsphenoidal surgery for pituitary adenoma and sellar reconstruction with only an onlay of regenerated oxidized cellulose. Patients were selected for this repair technique based on the absence of: (1) intraoperative identification of a CSF leak, (2) patulous diaphragm (expanded diaphragm sella herniating to or through sellar floor defect), and (3) other prohibiting comorbidities. Setting The present study was conducted at a tertiary care center. Participants In this study, pituitary adenoma patients were the participants. Outcome Measures Main outcome measure of the study is postoperative CSF leak. Results A total of 172 patients were identified. Of these, 153 were initial resections of pituitary adenomas. Gross total resection was achieved in 142 (82.6%) cases. Average tumor size was 2.2 ± 1.1 cm. Average tumor volume was 10.4 ± 19.8 cm 3 . No patients had intraoperative CSF leaks. All cases were repaired with only an onlay of regenerated oxidized cellulose. There were two postoperative CSF leaks (1.16%). Pre and postoperative SNOT-22 scores were 12.9 ± 11.9 and 14.3 ± 14.9 ( p = 0.796), respectively. Conclusion The use of an onlay of regenerated oxidized cellulose alone is an effective repair technique for select sellar defects. This technique does not result in increased postoperative CSF leak rates and avoids the higher relative cost and potential morbidity associated with more complex, multilayered closures.

Surgery with Post-Operative Endoscopy Improves Recurrence Detection in Sinonasal Malignancies.

OBJECTIVE: The mainstay of treatment in sinonasal malignancy (SNM) is surgery, and when combined with chemoradiation therapy, often leads to the best overall prognosis. Nasal endoscopy is essential for post-treatment surveillance along with physical exam and radiologic evaluation. The ability to directly visualize the sinus cavities after surgery may also improve early detection of tumor recurrence and is another reason to potentially advocate for surgery in these patients. METHODS: A retrospective chart review of medical records of patients with pathologically proven SNM was conducted from 2005 to 2019. RESULTS: The nasal cavity and maxillary sinus were the most common primary tumor sub-sites. The most common pathology was squamous cell carcinoma (42%). The median time to recurrence was 9.8 months. Recurrence was initially detected endoscopically in 34.3% patients, by imaging in 62.7% patients, and by physical exam in 3.0% patients. 67 (29%) total recurrences were detected on follow-up, of which 46 (68.7%) were local. Twenty-three of the local recurrences were identified via nasal endoscopy. Thirteen recurrences were identified via endoscopic surveillance within the surgically patent paranasal sinuses while 13 were identified within the nasal cavity; 5 patients had multiple sites of recurrence. CONCLUSION: Local recurrence of SNM is the most common site for recurrent disease and nasal endoscopy identified half of these cases. 50% of these recurrences were within the paranasal sinuses and would not have been easily identified if the sinuses were not open for inspection. Thus, open sinus cavities aid in the detection of tumor recurrence and is another advantage of surgery in the management of SNM.

Assessment of narcotic use in management of post-op pain after functional endoscopic sinus surgery.

OBJECTIVES: Pain and analgesic requirements after functional endoscopic sinus surgery (FESS) vary widely. This study aims to quantify pain after routine FESS and determine the most commonly used pain management regimen. METHODS: Retrospective chart review of 100 patients who underwent FESS from Oct 2017 to May 2019. Patients prospectively completed a daily pain diary and reported pain levels that were categorized into no pain (0), mild (1-3), moderate (4-7), or severe (8-10). Patients were categorized into narcotics, non-narcotics, combination, or none based on type of analgesic used. RESULTS: Sixty-nine patients were included. Majority of patients reported either mild (39%) or no pain (28%) during the first 5 PODs. Mean POD1 pain score was 3.98, which decreased with each subsequent POD. On POD1, 37% used opioids (n = 37), 32% used non-opioids (n = 32), 22% used a combination (n = 22), and 9% used no pain meds (n = 9). Mean number of narcotic pills used within the first 5 PODs was 2 pills on any given day. Age was inversely associated with reported POD1 pain scores (P = .003) and use of preoperative steroids in patients with sinonasal polyposis was associated with lower POD1 pain scores (P = .03). CONCLUSIONS: Even on POD1, majority of patients experienced either mild or no pain, and this decreases with each POD. Narcotics are grossly overprescribed and underutilized by patients postoperatively after FESS. We advocate for more judicious prescribing habits of narcotics by Otolaryngologists after FESS, and emphasize relying on non-narcotic alternatives like Acetaminophen or NSAIDS to diminish narcotic use and abuse in the postoperative period.

Straws Don't Suck: Are Straws Dangerous after Endoscopic Skull Base Surgery?

Objective Patients undergoing endoscopic endonasal surgery have historically been restricted from using straws postoperatively, due to the concern that this activity generates negative pressure. The objective of this study is to evaluate the pressure dynamics in the sinonasal cavity associated with the use of a straw. Methods Intracranial pressure catheters were placed in the nasal cavity of 20 healthy individuals. Pressure measurements were then recorded while participants drank liquids of different viscosities from a cup and from a straw. Measurements were recorded with and without subjects occluding their nose to simulate postoperative nasal obstruction. Results The average pressure in the nasal cavity while drinking water from a cup was -0.86 cmH 2 O, from a straw was -1.09 cmH 2 O, and while occluding the nose and using a straw was -0.81 cmH 2 O. The average pressure in the nasal cavity while drinking a milkshake from a cup was -0.98 cmH 2 O, from a straw was -1.88 cmH 2 O, and while occluding the nose and using a straw was -1.37 cmH 2 O. There was no statistically significant difference in pressure measurements when comparing either task or consistency ( p > 0.05). Conclusion Straw use is not associated with the generation of significant negative pressure in the nasal cavity. The pressure generated when drinking from a straw is not significantly different from that of drinking from a cup. This data suggest that straw use may be safe for patients following endoscopic skull base surgery, but further investigation is warranted.

Tolerance of Continuous Positive Airway Pressure After Sinonasal Surgery.

OBJECTIVES/HYPOTHESIS: For patients with obstructive sleep apnea (OSA) undergoing sinonasal surgery, there is a lack of consensus on the risk and appropriate postoperative use of continuous positive airway pressure (CPAP). The aim of this study was to assess the tolerability of restarting CPAP on postoperative day one. STUDY DESIGN: Prospective cohort study. METHODS: A prospective study on patients with OSA on CPAP who required a septoplasty/turbinectomy and/or functional endoscopic sinus surgery (FESS) was performed. Data from the memory card of a patient's CPAP machine and subjective information were obtained on the day of surgery and at scheduled follow-up visits. All subjects were instructed to restart CPAP on the first postoperative night. RESULTS: A total of 14 patients were analyzed; nine underwent FESS and five had a septoplasty/turbinectomy. There were no postoperative complications encountered. The only significant change in the first postoperative week was a reduction in the percentage of nights used over 4 hours (P < .05). By the third postoperative visit, average 22-item Sino-Nasal Outcome Test, Nasal Obstruction Symptom Evaluation, and CPAP tolerance scores improved from preoperative values. CPAP pressures, residual apnea-hypopnea index, and number of hours and mean percentage of nights used remained stable throughout the study period. CONCLUSIONS: Both quality-of-life and CPAP outcomes improved or remained the same when restarting CPAP immediately postoperatively. Combined with a lack of significant complications, this study suggests that CPAP is well-tolerated when restarted the day after a septoplasty/turbinectomy or FESS.

Quality of Life Outcomes in Patients With Sinonasal Malignancy After Definitive Treatment.

OBJECTIVES/HYPOTHESIS: To describe multidimensional quality of life (QOL) outcomes in patients with sinonasal malignancies (SNM). To elucidate factors predicting worse QOL in this population. STUDY DESIGN: Retrospective chart review at tertiary institution. METHODS: A retrospective chart review on patients treated for SNM from 2006 to 2019 at a tertiary medical center was conducted. QOL outcomes were measured using the Hospital Anxiety and Depression Scale (HADS) and the Functional Assessment Cancer Therapy - Nasopharynx (FACT-NP) score. A stepwise multiple linear regression analysis was conducted to assess factors predicting worse QOL. RESULTS: Eighty-one patients met inclusion criteria. Twelve (14.8%) patients had a subscale score >11 for anxiety (HADS-A) or depression (HADS-D) indicating significant anxiety or depression, at a median of 24 (8-68.5) months post treatment. The median FACT-NP total score was 136 (110-152). On multivariable analysis, advanced T classification, single status, and worse social support survey score were significant predictors of worse HADS score. Worse social support survey score was a significant predictor of worse total FACT-NP score. CONCLUSION: After adjusting for confounders, at a median of 24 months after completion of definitive therapy for SNM, advanced T classification and single relationship status were found to be significant predictors of anxiety and depression (based on HADS). A worse social support survey score was associated with worse anxiety, depression, and QOL (based on HADS and FACT-NP). Identifying these factors early may help to guide treatment and psychiatric referral to at-risk individuals after the treatment of SNM. LEVEL OF EVIDENCE: 3 Laryngoscope, 131:E2212-E2221, 2021.

Effect of Benralizumab in Patients With Severe Eosinophilic Asthma and Chronic Rhinosinusitis With Nasal Polyps: A Case Series.

OBJECTIVE: To analyze the effect of benralizumab in severe eosinophilic asthma (SA) and chronic rhinosinusitis with polyps (CRSwP). METHODS: Retrospective review of patients with both SA and CRSwP that were treated with benralizumab. Asthma controlled test (ACT), pulmonary function metrics (FEV1), Meltzer endoscopic polyp scores, SNOT-22 scores, were collected before and after at least 4 months of benralizumab therapy. RESULTS: 23 patients were included. The mean age at the time of enrollment into benralizumab therapy was 50.47 ± 17.3 years and majority (65.2%, n = 15) were males.Pulmonary Effects: In comparison to baseline ACT, scores at four months showed significant improvement (p = 0.03). In those with pre and post spirometry measurements, mean FEV1 showed significant increase following benralizumab therapy (p = 0.04) with a mean increase of 547 mL ± 597 mL following therapy.Sinonasal Effects: 78.5% of subjects on benralizumab had a significant improvement in sinonasal symptoms (p = 0.009) based on their SNOT-22 scores. Additionally, there was an improvement in endoscopic polyp scores, although not statistically significant, following benralizumab therapy (p = 0.2) with 54.5% patients showing improvement. CONCLUSION: Usage of benralizumab in patients with SA and CRSwNP can lead to significantly improved asthma control, lung function, and sinonasal quality of life. Additionally, in this patient population, there was a subset of patients that showed a significant reduction in polyp burden.

Loss of SMARCB1 Expression Confers Poor Prognosis to Sinonasal Undifferentiated Carcinoma.

Background Due to the diverse histopathologic features and variable survival rates seen in sinonasal undifferentiated carcinoma (SNUC), it is likely that this diagnostic entity is comprised of a heterogonous group of morphologically undifferentiated tumors. As advancements in molecular testing have led to a better understanding of tumor biology, it has become increasingly evident that SNUC may actually encompass several tumor subtypes with different clinical behavior. As a result, it is also likely that all SNUC patients cannot be treated in the same fashion. Recent investigations have identified loss of the tumor suppressor SMARCB1 (INI1) expression in a subset of undifferentiated sinonasal tumors and extrasinonasal tumors and, studies have suggested that this genetic aberration may be a poor prognostic marker. The objective of this study was to identify differential expression of SMARCB1 in SNUC and to analyze and compare the survival outcomes in SNUC patients with and without SMARCB1 expression. Methods All cases of undifferentiated or poorly differentiated neoplasms of the sinonasal tract treated between 2007 and 2018 at a single tertiary care institution were selected. All cases of SNUC were tested for SMARCB1 status by immunohistochemistry (IHC). Clinical parameters were analyzed using Student's t -test and Fischer's test. Kaplan-Meier methods were used to estimate survival durations, while comparison between both the subgroups was done using the log-rank test. Statistical analysis was performed with the use of SPSS software, Version 25 (IBM, New York, NY, United States). Results Fourteen cases of SNUC were identified. Approximately two-thirds (64%; n = 9) of patients were male and the majority (79%; n = 11) were between fifth to seventh decade. Skull base and orbital invasion were seen in 79% ( n = 11) and 93% ( n = 13) of cases, respectively. Fifty-seven percent of tumors ( n = 8) retained SMARCB1 expression by IHC (SR-SNUC), while the remaining 43% ( n = 6) showed loss of SMARCB1 expression and, thus, were considered as SMARCB1 -deficient (SD-SNUC). Although clinicopathological features and treatment modalities were similar, SD-SNUC showed poorer (OS: p = 0.07; disease free survival [DFS]: p = 0.02) overall survival (OS) and DFS on Kaplan-Meier curves. Additionally, SD-SNUC showed higher recurrence (75 vs. 17%) and mortality (67 vs. 14%) (hazard rate = 8.562; p = 0.05) rates. Both OS (28.82 ± 31.15 vs. 53.24 ± 37.50) and DFS durations (10.62 ± 10.26 vs. 43.79 ± 40.97) were consistently worse for SD-SNUC. Five-year survival probabilities were lower for SD-SNUC (0.33 vs. 0.85). Conclusion SNUC represents a heterogeneous group of undifferentiated sinonasal malignancies. Based on the status of SMARCB1 expression, the two subgroups SD-SNUC and SR-SNUC appear to represent distinct clinical entities, with loss of SMARCB1 expression conferring an overall worse prognosis.

Preoperative Screening for Obstructive Sleep Apnea Prior to Endoscopic Skull Base Surgery: A Survey of the North American Skull Base Society.

BACKGROUND: Obstructive sleep apnea (OSA) is a commonly seen comorbidity in patients undergoing endoscopic skull base surgery and its presence may influence perioperative decision-making. Current practice patterns for preoperative screening of OSA are poorly understood. OBJECTIVE: The objective of this study was to assess how endoscopic skull base surgeons screen for OSA, and how knowledge of OSA affects perioperative decision-making. METHODS: Seven question survey distributed to members of the North American Skull Base Society. RESULTS: Eighty-eight responses (10% response rate) were received. 60% of respondents were from academic centers who personally performed >50 cases per year. Most respondents noted that preoperative knowledge of OSA and its severity affected postoperative care and increased their concern for complications. Half of respondents noted that preoperative knowledge of OSA and its severity affects intraoperative skull base reconstruction decision-making. 70% of respondents did not have a preoperative OSA screening protocol. Body mass index and patient history were most frequently used by those who screened. Validated screening questionnaires were rarely used. 76% of respondents agreed or somewhat agreed that a preoperative polysomnogram should ideally be performed for patients with suspected OSA; however, 50% of respondents reported that <20% of their patients with suspected OSA are advised to obtain a preoperative polysomnogram. CONCLUSION: This study reveals that most endoscopic skull base surgeons agree that OSA affects postoperative patient care, but only a minority have a preoperative screening protocol in place. Additional study is needed to assess the most appropriate screening methods and protocols for OSA patients undergoing endoscopic skull base surgery.
