RESUMEN
Background Understanding the genetic basis for the molecular classification of sinonasal undifferentiated carcinoma (SNUC) based on SMARCB1 may improve our understating regarding the nature of the disease. The objective of the study was to compare the genetic profile of SMARCB1-retained (SR-SNUC) and SMARCB1-deficient SNUC (SD-SNUC). Methods Formalin-fixed, paraffin-embedded tissue from treatment-naive patients with SNUC were selected. Three cases of SR-SNUC, four cases of SD-SNUC, and four samples of nontumor tissue (control samples) were selected. Ribonucleic acid (RNA) sequencing was performed. Results SR-SNUC had a higher number of variants (1 variant for every 15,000 bases) compared with SD-SNUC (1 variant every 29,000 bases). The ratio of missense to silent mutation ratio was higher for SR-SNUC (0.8) as compared with SD-SNUC (0.7). Approximately 1,500 genes were differentially expressed between SR-SNUC and SD-SNUC. The genes that had a higher expression in SR-SNUC included TPD52L1, B3GNT3, GFY, TJP3, ELL3, CYP4F3, ALDH3B2, CKMT1B, VIPR1, SLC7A5, PPP2R2C, UPK3B, MUC1, ELF5, STY7, and H2AC14. The gene that had a higher expression in SD-SNUC was ZFHX4. Most of these genes were related to either protein translation or immune regulation. The most common ( n = 3, 75%) mechanisms of loss of SMARCB1 gene in SD-SNUC was loss of heterozygosity. Conclusion RNA sequencing is a viable and informative approach for genomic profiling of archival SNUC samples. Both SR-SNUC and SD-SNUC were noted to have distinct genetic profiles underlying the molecular classification of these diseases.
RESUMEN
The goal of this American Rhinologic Society expert practice statement (EPS) is to summarize the best available evidence regarding postoperative precautions for patients following endoscopic skull base surgery for intradural pathology. These topics include the administration of postoperative nasal hygiene; patient mobilization and activity level; the resumption of continuous positive airway pressure in patients with obstructive sleep apnea; and the timing and capacity with which a patient may be subjected to barotrauma, such as air travel postoperatively. This EPS was developed following the recommended methodology and approval process as previously outlined. Given the diverse practices and limited agreement on the accepted principles regarding postoperative precautions for patients following skull base surgery, this EPS seeks to summarize the existing literature and provide clinically relevant guidance to bring clarity to these differing practice patterns. Following a modified Delphi approach, four statements were developed, all of which reached consensus. Because of the paucity of literature on these topics, these statements represent a summation of the limited literature and the experts' opinions. These statements and the accompanying evidence are summarized below, along with an assessment of future needs.
RESUMEN
KEY POINTS: This follow-up dual-institutional and longitudinal study further evaluated for underlying gender biases in LORs for rhinology fellowship. Explicit and implicit linguistic gender bias was found, heavily favoring male applicants.
RESUMEN
BACKGROUND: Olfactory dysfunction (OD) affects many survivors of COVID-19. Prior studies have investigated the use of platelet-rich plasma (PRP) injections for OD. We describe the first randomized controlled trial investigating topical PRP for OD treatment and contribute to existing literature illustrating PRP as an emerging therapeutic. METHODS: This is a single-blinded, randomized controlled trial conducted from July 2022 to December 2023. Adult patients with OD ≥6 months secondary to COVID-19 with Brief Smell Identification Test (BSIT) scores of ≤8/12 or SCENTinel odor intensity of ≤40/100 were included. Patients were randomized to three, monthly PRP or placebo-impregnated Surgifoam treatments into bilateral olfactory clefts. The BSIT, SCENTinel, and Questionnaire of Olfactory Disorders-Negative Statements (QOD-NS) were completed monthly through month 12. RESULTS: Of 104 patients screened, 83 participated. No significant differences in age, OD duration, BSIT, SCENTinel, or QOD-NS scores were found between PRP (n = 42) and placebo (n = 41) patients at baseline. PRP patients experienced a statistically significant increase in BSIT scores from baseline at months 5â9, 11, and 12, while placebo patients did not (p < 0.05). However, total BSIT scores were similar between the two groups throughout the study. Neither the SCENTinel odor intensity scores nor the change from baseline were significantly different between the treatment groups. At month 12, PRP patients experienced minor improvement in OD-related quality-of-life compared with placebo. CONCLUSIONS: This study is the first to describe topical PRP as a safe, experimental treatment for OD in humans. PRP may impact odor identification in post-COVID-19 OD patients, although the lack of difference in total BSIT scores highlights the need for further study.
RESUMEN
BACKGROUND: This is the largest study in North America investigating olfactory outcomes after pituitary surgery to date. OBJECTIVE: Characterize factors associated with subjective olfactory dysfunction (OD) and worsened sinonasal quality-of-life (QOL) after endoscopic TSA. METHODS: Patients undergoing primary TSA for secreting and non-secreting pituitary adenomas between 2017 and 2021 with pre- and post-operative SNOT-22 scores were included. Subjective OD was determined by the smell/taste dysfunction question on the SNOT-22 (smell-SNOT). RESULTS: 159 patients with pre- and post-operative SNOT-22 scores were included. Average total SNOT-22 scores worsened from pre-operative (16.91 ± 16.91) to POM1 (25.15 ± 20.83, P < .001), with no difference from pre-operative (16.40 ± 15.88) to POM6 (16.27 ± 17.92, P = .936) or pre-operative (13.63 ± 13.54) to POM12 (12.60 ± 16.45, P = .651). Average smell-SNOT scores worsened from pre-operative (0.40 ± 1.27) to POM1 (2.09 ± 2.01, P < .001), and pre-operative (0.46 ± 1.29) to POM6 (1.13 ± 2.45, P = .002), with no difference from pre-operative (0.40 ± 1.07) to POM12 (0.71 ± 1.32, P = .100). Female gender had a 0.9-point (95% CI 0.1 to 1.6) P = .021, increase in smell-SNOT at POM1, resolving by POM6 (0.1 [-0.9 to 1.1], P = .800) and POM12 (0.0 [-1.0 to 0.9], P = .942). Septoplasty with tunnel approach had a 1.1 [0.2 to 2.0] out of 5-point (P = .023) increase in smell-SNOT at POM1, resolving by POM6 (0.2 [-1.1 to 1.6], P = .764) and POM12 (0.4 [-0.9 to 1.6], P = .567). Female gender had a 9.5 (4.0 to 15.1)-point (P = .001) increase in SNOT-22 scores at POM1, resolving by POM6 (3.4 [-3.0 to 9.8], P = .292) and POM12 (6.4 [-5.4 to 18.2], P = .276). Intra-operative CSF leak had an 8.6 [2.1 to 15.1]-point (P = .009) increase in SNOT-22 scores at POM1, resolving by POM6 (5.4 [-1.7 to 12.5], P = .135), and POM12 (1.1 [-12.9 to 15.1], P = .873). CONCLUSION: Changes in subjective olfaction and sinonasal QOL after TSA may be associated with gender, operative approach, and intra-operative CSF leak, resolving 6-12 months post-operatively.

The goal of this American Rhinologic Society expert practice statement (EPS) is to summarize the best available evidence for technical factors that optimize outcomes in skull base reconstruction following endoscopic skull base surgery for intradural pathologies. These topics include the use of free mucosal grafts versus vascularized pedicled nasoseptal flaps; the use of autologous versus synthetic grafts; and the roles of lumbar drains, dural sealants, and nasal packing. This EPS was developed following the recommended methodology and approval process as previously outlined. As there are a myriad of techniques and limited agreement on the accepted principles of skull base reconstruction, this EPS aims to summarize the existing evidence and provide clinically meaningful guidance on these divergent practices. Following a modified Delphi approach, five statements were developed, four of which reached consensus and one of which reached near consensus. These statements and the accompanying evidence are summarized along with an assessment of future needs.
RESUMEN
KEY POINTS: Silent sinus syndrome (SSS) and chronic maxillary atelectasis (CMA) represent an overlapping clinical entity, both likely lying on the spectrum of one disease process. There is widespread inconsistency of diagnosis in the literature of reported cases of SSS and CMA. We propose a novel, comprehensive staging system to simplify diagnosis and inform management.

BACKGROUND: Post-COVID parosmia may be due to dysautonomia and sympathetic hyperresponsiveness, which can be attenuated by stellate ganglion block (SGB). This study evaluates SGB as a treatment for post-COVID olfactory dysfunction (OD). METHODS: Retrospective case series with prospective data of patients with post-COVID OD undergoing unilateral (UL) or bilateral (BL) SGB. Patients completed Brief Smell Identification Tests (BSIT) (12 points maximum) and post-procedure surveys including parosmia severity scores on a scale of 1 (absent) to 10 (severe). Scores were compared from before treatment (pre-SGB) to after first (SGB1) or second (SGB2) treatments in overall, UL, and BL cohorts. RESULTS: Forty-seven patients with post-COVID OD underwent SGB, including 23 UL and 24 BL. Twenty patients completed pre- and post-SGB BSITs (eight UL and 12 BL). Twenty-eight patients completed postprocedure surveys (11 UL and 17 BL). There were no differences in BSIT scores from pre-SGB to post-SGB1 or post-SGB2 for the overall (p = 0.098), UL (p = 0.168), or BL (p = 0.230) cohorts. Parosmia severity for the overall cohort improved from pre-SGB (8.82 ± 1.28) to post-SGB1 (6.79 ± 2.38) and post-SGB2 (5.41 ± 2.35), with significant differences from pre-SGB to post-SGB1 (p < 0.001) and pre-SGB to post-SGB2 (p < 0.001), but not post-SGB1 to post-SGB2 (p = 0.130). Number of parosmia triggers decreased for overall (p = 0.002), UL (p = 0.030) and BL (p = 0.024) cohorts. Quality of life (QOL) improved for all cohorts regarding food enjoyment, meal preparation, and socialization (p < 0.05). CONCLUSION: SGB may improve subjective parosmia and QOL for patients with post-COVID OD, however it may not affect odor identification. Further placebo-controlled studies are warranted.

This is the first study to examine chronic rhinosinusitis (CRS) outcomes after starting immunoglobulin (Ig) replacement therapy for patients with primary (PID) and secondary immunodeficiency (SID). This is a retrospective review of patients diagnosed with CRS from 2018 to 2022 prior to initiating Ig therapy for the treatment of PID or SID. Outcomes included medication use and Sinonasal Outcome Test (SNOT-22) scores. Ten patients met the inclusion criteria. PID and SID patients had a decrease in antibiotics (PID: 9.40 to 3.20, P = .05, SID: 8.20 to 2.00, P = .04) and steroids (PID: (5.40 to 0.60; P = .06; SID: 2.20 to 0.20, P = .047) prescribed in the year after Ig compared to the year prior. Patients with SID had a decrease in mean SNOT-22 scores by 12 months after Ig (47.50 to 20.50, P = 0.03). Patients receiving Ig for PID and SID showed decreased medication use and SID patients experienced subjective improvement in CRS symptoms in year-over-year comparison.

OBJECTIVE: Encephaloceles of the lateral sphenoid sinus are rare. Originally believed to be due to defects in a patent lateral craniopharyngeal canal (Sternberg canal), they are now thought to originate more commonly from idiopathic intracranial hypertension, not unlike encephaloceles elsewhere in the skull base. A new classification of these encephaloceles was recently introduced, which divided them in relation to the foramen rotundum. Whether this classification can be applied to a larger cohort from multiple institutions and whether it might be useful in predicting outcome is unknown. Thus, the authors' goal was to divide a multiinstitutional cohort of patients with lateral sphenoid encephaloceles into four subtypes to determine their incidence and any correlation with surgical outcome. METHODS: A multicenter retrospective review of prospectively acquired databases was carried out across three institutions. Cases were categorized into one of four subtypes (type I, Sternberg canal; type II, medial to rotundum; type III, lateral to rotundum; and type IV, both medial and lateral with rotundum enlargement). Demographic and outcome metrics were collected. Kaplan-Meyer curves were used to determine the rate of recurrence after surgical repair. RESULTS: A total of 49 patients (71% female) were included. The average BMI was 32.8. All encephaloceles fell within the classification scheme. Type III was the most common (71.4%), followed by type IV (16.3%), type II (10.2%), and type I (2%). Cases were repaired endonasally, via a transpterygoidal approach. Lumbar drains were placed in 78% of cases. A variety of materials was used for closure, with a nasoseptal flap used in 65%. After a mean follow-up of 47 months, there were 4 (8%) CSF leak recurrences, all in patients with type III or type IV leaks and all within 1 year of the first repair. Two leaks were fixed with ventriculoperitoneal shunt and reoperation, 1 with ventriculoperitoneal shunt only, and 1 with a lumbar drain only. Of 45 patients in whom detailed information was available, there were 12 (26.7%) with postoperative dry eye or facial numbness, with facial numbness occurring in type III or type IV defects only. CONCLUSIONS: Endoscopic endonasal repair of lateral sphenoid wing encephaloceles is highly successful, but repair may lead to dry eye or facial numbness. True Sternberg (type I) leaks were uncommon. Failures and facial numbness occurred only in patients with type III and type IV leaks.

INTRODUCTION: Chronic rhinosinusitis with nasal polyposis (CRSwNP) is often treated with endoscopic sinus surgery (ESS); however, patients may require revision surgery due to recurrence. To date, no studies have compared outcomes for combined surgery and biologic therapy for CRSwNP compared with biologic therapy alone. METHODS: Retrospective case-control study of CRSwNP patients who underwent ESS while on dupilumab or mepolizumab (ESS-biologic cohort) compared with CRSwNP patients on biologic therapy (biologic-only controls). Cohorts were matched according to indication, aspirin-exacerbated respiratory disease (AERD), sinonasal outcome test-22 (SNOT-22), and total polyp scores. RESULTS: Sixteen patients underwent ESS while on biologic therapy (13 dupilumab and 3 mepolizumab). Sixteen patients were biologic-only controls. There were no significant differences between indication, baseline SNOT-22 scores, polyp scores, and AERD status between cohorts. Patients underwent surgery a median of 33 days after starting biologic therapy. After 12 months of follow-up, the total polyp score for the ESS-biologic cohort decreased from 4.73 to 0.09 compared with a decrease from 5.22 to 3.38 for the biologic-only controls (95% confidence interval [CI] of difference: -5.37 to -1.38, Cohen's d: 2.40, p = 0.005). In the ESS-dupilumab subanalysis, the ESS-dupilumab cohort had a significant reduction in polyp burden from 4.85 to 0.00 compared with 4.88 to 3.50 for the controls (95% CI of difference: -5.68 to -1.32, Cohen's d: -1.69, p = 0.009). CONCLUSION: In CRSwNP patients, combined ESS and biologic therapy results in a significant and sustained decrease in polyp burden compared with biologic therapy alone. Larger studies are warranted to further examine the impact of combined therapy.

Objectives Cerebrospinal fluid (CSF) leaks of the anterior cranial base are frequently repaired with endonasal, multilayered reconstructions. Vascularized tissue flaps are superior to free mucosal grafts and biomaterials in many cases. Limitations of previously described flaps include reach, rotation, pedicle availability, and postoperative sinonasal morbidity. The objective of this study is to describe the superiorly based middle turbinate flap, a novel vascularized mucosal reconstruction option, and to present a case series demonstrating flap utility. Design Cadaveric feasibility study with technical description and illustrative case series. Setting Tertiary medical center. Participants Three silicone-injected cadaveric specimens (6 sides); 7 patients with CSF rhinorrhea from bony dehiscence of the anterior cranial fossa repaired with a superiorly based middle turbinate flap. Outcome Measures Cadaveric feasibility, in vivo repair outcomes, sinonasal symptoms, and postoperative healing. Results Cadaveric dissection demonstrated a consistent vascular plexus arising from the anterior and posterior ethmoid arteries, originating at the superior attachment of the middle turbinate and traveling inferiorly to supply the mucosa of the middle turbinate. Mean surface area of the flap was 776.67 ± 114.60 mm 2 . The clinical series of 7 patients involved leaks around the cribriform plate and fovea ethmoidalis. There were no instances of repair failure. All cases showed rapid and complete remucosalization without significant sinonasal morbidity. Conclusion The superiorly based middle turbinate flap is a reliable, versatile, and effective option for a vascularized mucosal flap onlay that can be used in anterior skull base reconstruction. This flap is particularly useful in the repair of defects involving the cribriform plate and fovea ethmoidalis.
RESUMEN
OBJECTIVES: Among the transsphenoidal (TSS) approaches to pituitary tumors, the microscopic approach (MA) has historically been the predominant technique with the increasing adoption of the endoscopic approach (EA). This study investigates national trends in TSS approaches and postoperative outcomes for MA and EA through 2021. METHODS: The TriNetX database was queried for patients undergoing TSS (MA and EA) between 2010 and 2021. Data were collected on demographics, geographic distribution of surgical centers, postoperative complications, stereotactic radiosurgery (SRT), repeat surgery, and postoperative emergency department (ED) visits. RESULTS: 8644 TSS cases were queried between 2010 and 2021. MA rates were highest until 2013 when rates of EA (52%) surpassed MA (48%) and continued to increase through 2021 (81%). From 2010 to 2015 EA had higher odds of a postoperative CSF leak (OR 3.40) and diabetes insipidus (DI (OR 2.30)) versus MA (p < 0.05); from 2016 to 2021 differences were not significant. Although there was no significant difference among approaches from 2010 to 2015 for syndrome of inappropriate antidiuretic hormone (SIADH), hyponatremia, or bacterial meningitis, from 2016 to 2021 EA had lower odds of SIADH (OR 0.54) and hyponatremia (OR 0.71), and higher odds of meningitis (OR 1.79) versus MA (p < 0.05). EA had higher odds of additional surgery (either EA or MA) after initial surgery from 2010 to 2021. From 2010 to 2015 EA had lower odds of postoperative SRT compared to MA, whereas in 2016-2021 there was no statistical difference among approaches. CONCLUSION: This study demonstrates increasing EA adoption for TSS in the United States since 2013. Complication rates have overall improved for EA compared to MA, potentially as a result of improving surgeon familiarity and experience. LEVEL OF EVIDENCE: 4 Laryngoscope, 133:2135-2140, 2023.

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.

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.

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.

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.
