RESUMO
STUDY OBJECTIVES: Drug-induced sleep endoscopy with positive airway pressure evaluates the collapsibility of the upper airway. It is currently unknown whether body position affects this assessment. We sought to determine whether the collapsibility of the airway may change with head of bed elevation. METHODS: A prospective, consecutive cohort study was performed by 2 sleep surgeons at a tertiary care center. Inclusion criteria included adults 18 years of age and older with obstructive sleep apnea who were intolerant to continuous positive airway pressure therapy. Patients underwent drug-induced sleep endoscopy with positive airway pressure to evaluate them for alternative treatment options. Patients were evaluated in supine position with the head of bed both level and elevated to 30°. The airway was evaluated using the standardized VOTE scoring system in both positions. RESULTS: The 61 patients included in the study were predominantly male (70.5%), middle-aged (51.2 years), and obese (body mass index, 30.2 kg/m2) with moderate-to-severe obstructive sleep apnea (apnea-hypopnea index, 34.1 events/h). The cohort consisted of predominantly positional obstructive sleep apnea (mean supine apnea-hypopnea index 48.7 events/h, nonsupine apnea-hypopnea index 20.8 events/h). All 4 sites of the upper airway demonstrated a significant decrease in airway opening pressures with the head of bed elevated compared to level (P < .01 for all sites). There was no significant difference in VOTE scoring between level and upright positions. CONCLUSIONS: Patients with the head of bed elevated to 30° have a significantly lower degree of airway collapsibility compared to patients in the level position but no significant change in VOTE scoring was observed.

OBJECTIVE: To analyze clinical and radiographic features that may impact the rate of focal hyperostosis (FH) on computed tomography (CT) for primary and recurrent sinonasal inverted papillomas (IPs) as well as highlight factors that may affect concordance between FH and IP true attachment point (TAP). METHODS: All IPs resected between 2006 and 2022 were retrospectively reviewed. CTs were read by a neuroradiologist blinded to operative details. IP with malignancy was excluded. Operative reports and long-term follow-up data were evaluated. RESULTS: Of 92 IPs, 60.1% had FH, 25% had no CT bony changes, and 20.7% were revision cases. The recurrence rate for rhinologists was 10.5% overall and 7.3% for primary IPs. Primary and revision IPs had a similar rate of FH (63% vs. 52.6%; p = 0.646) and FH-TAP agreement (71.7% vs. 90%; p = 0.664). Nasal cavity IPs, especially with septal attachment, were more likely to lack bony changes on CT (57.1%) compared to other subsites (p = 0.018). Recurrent tumors were 16 mm larger on average (55 mm vs. 39 mm; p = 0.008). FH (75.0% vs. 60.9%; p = 0.295), FH-TAP concordance (91.7% vs. 74.4%; p = 0.094), and secondary IP (18.8% vs. 20.3%; p = 0.889) rates were similar between recurrent and nonrecurrent tumors. CONCLUSION: Primary and revision IPs have a similar rate of FH and FH-TAP agreement. Nasal cavity IPs are less likely to exhibit bony CT changes. Lower recurrence was associated with smaller size and fellowship training but not multiple TAPs, revision, FH absence, or FH-TAP discordance. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:1591-1596, 2024.

OBJECTIVES: Endoscopic medial maxillectomy (EMM) is an effective intervention for patients with recalcitrant maxillary sinusitis after previous middle meatal antrostomy. The pathophysiology of refractory maxillary sinusitis is incompletely understood. We aim to identify trends in structured histopathology (SHP) to better understand how tissue architecture changes contribute to refractory sinusitis and impaired mucociliary clearance. METHODS: All patients who underwent EMM or standard maxillary antrostomy for recalcitrant maxillary sinusitis of various forms were included. Retrospective chart review was conducted to collect information on demographics, disease characteristics, comorbid conditions, culture data, and SHP reports. Chi-squared and logistic regression analyses were performed for SHP variables. RESULTS: Forty-one patients who underwent EMM and 464 patients who underwent maxillary antrostomy were included. On average, the EMM cohort was 10 years older (60.9 years vs. 51.1 years; p = 0.001) and more often had a history of prior sinus procedures (73.2% vs. 40.9%; p < 0.001). EMM patients had higher rates of fibrosis (34.1% vs. 15.1%, p = 0.002), and this remained statistically significant when controlling for prior sinus procedures and nasal polyposis (p = 0.001). Cultures positive for pseudomonas aeruginosa (38.2% vs. 5.6%, p < 0.001) and coagulase negative staphylococcus (47.1% vs. 23.5%, p = 0.003) were more prevalent in the EMM group. CONCLUSION: Fibrosis and bacterial infections with Pseudomonas and coagulase negative Staphylococcus were more prevalent in patients requiring EMM. This may contribute to the multifactorial etiology of impaired mucociliary clearance in patients with recalcitrant maxillary sinusitis. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:2646-2652, 2024.

OBJECTIVE: To explore how diabetes mellitus impacts chronic rhinosinusitis clinically and on structured histopathology to provide insights on new potential chronic rhinosinusitis endotypes. STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary academic center. METHODS: A retrospective study of chronic rhinosinusitis patients who underwent functional endoscopic sinus surgery from 2015 to 2020 was performed. Structured 13-variable histopathology reports were generated from intraoperative sinonasal specimens. These variables were compared against demographic factors, comorbidities, culture data, and preoperative Lund-Mackay and SNOT-22 scores using logistic regression. RESULTS: There were 411 patients, including 52 diabetics. Diabetes was associated with higher mean body mass index (34.9 vs 29.2; p < .001), age (57.8 vs 48.0; p < .001), and Gram-negative (40.2% vs 22.7%; p < .030) and coagulase-negative Staphylococcus (49.0% vs 28.5%; p = .008) culture rates. Black (23.1% vs 18.7%) and Hispanic (23.1% vs 8.6%) races were more common with diabetes (p = .026). Gender, smoking, polyp status, and Lund-Mackay and SNOT-22 scores did not differ between groups. Diabetics had more fungal elements (13.5% vs 3.3%, p = .018); no other histopathological differences were seen. When controlling for demographic variables and comorbidities, diabetes independently predicted the presence of fungal elements (HR 4.38, p = .018). CONCLUSION: Diabetic chronic rhinosinusitis patients demonstrated increased fungal elements on structured histopathology. Other histopathological features were unaffected by diabetes. These findings may have important implications on the medical and surgical management of diabetic chronic rhinosinusitis patients in which early fungal disease assessment is paramount.

OBJECTIVE: Structured histopathology (SHP) is a method of analyzing sinonasal tissue to characterize endotypes of chronic rhinosinusitis with nasal polyps (CRSwNP). Allergic fungal rhinosinusitis (AFRS) shares several features with certain endotypes of CRSwNP. Our objective was to compare the histopathology of AFRS and eosinophilic CRSwNP to further understand whether they are separate endotypes or disease entities altogether. METHODS: A retrospective review of AFRS and CRSwNP patients undergoing endoscopic sinus surgery was performed. Data were collected on demographics, comorbidities, subjective and objective severity scores, and 13-variable SHP reports. CRSwNP patients with >10 eosinophils per high-power field (eCRSwNP) were included. Chi-squared and t-tests were used for statistical analysis. RESULTS: A total of 29 AFRS and 108 eCRSwNP patients were identified. AFRS patients were younger and more often Black. Symptom severity scores (SNOT-22, Lund-MacKay, and Lund-Kennedy) were uniform between groups. AFRS patients had a higher rate of Charcot-Leyden crystals (41.4% vs. 10.2%; p < 0.001). Severe degree of inflammation, eosinophilic inflammatory predominance, eosinophil aggregates, subepithelial edema, and basement membrane thickening were common in both groups, and their rates were not statistically significantly different between groups. Metaplasia, ulceration, fibrosis, and hyperplastic/papillary change rates were low (<30%) and similar between groups. CONCLUSION: The SHP of eCRSwNP and AFRS are highly consistent, which suggests AFRS is a severe subtype of CRSwNP overall rather than a separate disease entity. This also lends credence to AFRS belonging on the endotypic spectrum of CRSwNP. LEVEL OF EVIDENCE: 3 Laryngoscope, 2023.
RESUMO
BACKGROUND: Biologics are effective for chronic rhinosinusitis with nasal polyposis (CRSwNP) by reducing type 2 inflammation. Nonresponders often require functional endoscopic sinus surgery (FESS) and represent a challenging population potentially due to non-type 2 pathophysiology. This study characterizes the histopathologic features of biologic nonresponders. METHODS: A retrospective review of 257 CRSwNP patients undergoing FESS was conducted. The biologic nonresponder group included patients with prior biologic therapy who exhibited persistent symptoms and polyp burden. Those with CRSwNP not prescribed biologic therapy were selected as controls. Demographics, comorbidities, and structured histopathology consisting of 13 variables were collected. RESULTS: Of 257 CRSwNP patients, 20 were on biologics prior to FESS. Fourteen patients (70.0%) received dupilumab, one (5.0%) received mepolizumab, one (5.0%) received omalizumab, and four (20.0%) tried multiple biologics. The mean age for the biologic nonresponder group was 45.8 years compared to 50.4 years for the controls. Nonresponders had a significantly increased incidence of reduced tissue eosinophilia, defined as <5 per high power field (55% vs. 31.2%, p = 0.044) and increased basement membrane thickening (100% vs. 78.1%, p = 0.019). The remaining 11 variables did not reach statistical significance. CONCLUSION: Histopathologic analysis of biologic nonresponders demonstrates decreased eosinophilia and thickened basement membranes. These findings, particularly low tissue eosinophils, are consistent with a non-type 2 CRSwNP that may be recalcitrant to biologic therapies. Histopathologic analysis done in conjunction with FESS may aid clinicians in understanding response to biologic therapies in patients with CRSwNP who have persistent symptom burden necessitating FESS.

This review discusses current and actively debated perioperative interventions aimed at improving patient safety and the quality of parotidectomy. Relevant high-impact literature pertaining to preoperative diagnostic modalities, intraoperative surgical techniques, and postoperative care will be described.
RESUMO
OBJECTIVE: To highlight various patient, tumor, diagnostic, and treatment characteristics of laryngeal chondrosarcoma (LC) as well as elucidate factors that may independently affect overall survival (OS) for LCs. STUDY DESIGN: Retrospective cohort study. SETTING: National Cancer Database (NCDB). METHODS: All LC cases from 2004 to 2016 were extracted from the NCDB. Several demographic, diagnostic, and treatment variables were compared between LC subgroups using χ2 and analysis of variance tests. Univariate and multivariate survival analyses were performed for LCs using univariate Kaplan-Meier analysis and Cox proportional hazards regression models. RESULTS: There were 348 LCs included in the main cohort. LCs were predominantly non-Hispanic white males with similar rates of private and government insurance (49.4% vs 45.4%). Most LCs (81.6%) underwent primary surgery, particularly partial and total laryngectomy. The 1-, 5-, and 10-year survivals for LC were 95.7%, 88.2%, and 66.3%, respectively. On multivariate analysis, lack of insurance (P = .019; hazard ratio [HR], 8.21; 95% CI, 1.40-48.03), high grade (P = .001; HR, 13.51; 95% CI, 3.08-59.26), and myxoid/dedifferentiated histological subtypes (P = .0111; HR, 10.74; 95% CI, 1.71-67.33) correlated with worse OS. No difference in OS was found between partial and total laryngectomy. CONCLUSION: This is the first multivariate survival analysis and largest single cohort study of LCs in the literature. Overall, LCs enjoy an excellent prognosis, with insurance status, grade, and histology as the main predictors of survival.

BACKGROUND: The use of balloon catheter dilation (BCD) to treat chronic rhinosinusitis has increased dramatically since its conception, necessitating further characterization of BCD providers and trends in its usage. Medicare data on BCD providers have made it possible to study recent demographic patterns. There has also been an increase in mid-level providers' scope of otolaryngologic practice that is not well defined. OBJECTIVE: To better understand BCD adoption by studying volume of BCD procedures as well as training, geography, and practice socioeconomic characteristics of BCD providers for Medicare beneficiaries. METHODS: We reviewed Medicare Provider Utilization and Payment Data Public Use Files for 2014 and 2015 for providers with claims for BCD of the sinuses. We extracted provider zip code, state, gender, and number of services per BCD code. We obtained median household income by zip code and geographic region based on US Census Bureau data. Providers were classified using an Internet search to determine practice setting and type of specialty training/certification. RESULTS: In 2014 and 2015, 428 providers performed 42 494 BCDs billed to Medicare beneficiaries. Among BCD providers, 5.1% were female, 98.1% had Doctor of Medicine/Doctor of Osteopathic Medicine credentials, and 1.9% had nurse practitioner/physician assistant credentials. Over the 2-year period, the median number of BCDs was 63 for physicians and 37 for mid-level providers. Fellowship-trained rhinologists performed a median of 38 BCDs over 2 years. The most common subspecialty certification/training was in facial plastics and reconstructive surgery. The majority of providers (63.8%) performed 1 to 99 BCDs over the 2 years. In the South, there were 21.9 BCD procedures performed per 100 000 people compared to 7.3 in the Northeast, 9.3 in the Midwest, and 8.5 in the West. CONCLUSION: There is a large range in total BCD procedures performed by individual providers, and this varies by certain provider characteristics. Mid-level providers have emerged as a significant population performing BCD.

The goal of this study was to investigate recent changes in stone composition and patient demographics to identify factors influencing stone formation for the purpose of reducing the incidence of urolithiasis and preventing stone recurrence. This retrospective analysis includes patients who underwent percutaneous nephrolithotripsy or ureteroscopy at our institution from 2005 to 2015. Northwestern Medicine Enterprise Data Warehouse was used to retrieve demographic information and stone composition analyses. The composition of mixed stones containing uric acid (UA) and calcium oxalate monohydrate (COM) was analyzed further. Chi-squared tests were used for categorical variables and logistic regression was used to assess trends. From 2005 to 2015, 5268 stones were treated. COM was predominant in 42.2% and only 16.6% were pure. The male/female ratio decreased significantly from 1.8 to 1.08 and patient age increased (p < 0.001) with 45.6% of patients being 60 or older in 2015. Females formed more CO dihydrate (COD; p = 0.008) and struvite (p = 0.001) overall. The incidence of COM (p = 0.007) and UA (p < 0.001) rose significantly in men whereas both sexes saw a decrease in carbonate apatite (CA; p < 0.001). COM increased considerably from 12 to 75% amongst mixed stones with UA over the 11-year span. We concluded that stone formers have become older and more gender-equal. The increase in female patients parallels the increase in female obesity in the US. The rising predominance of COM, including when mixed with UA, and the scarcity of pure stones indicates it may be necessary to develop new approaches to managing and preventing urolithiasis.

OBJECTIVE: To analyze the outcomes of upper pole access during percutaneous nephrolithotomy (PCNL), an option pole often avoided due to the concern for pleural injury. METHODS: We retrospectively collected data on patients undergoing PCNL at our institution. Patients were divided into 3 groups according to access: supracostal upper calyx (group 1), subcostal upper calyx (group 2), and nonupper calyx (group 3). Preoperative imaging was reviewed to assess stone burden, Hounsfield units (HU), location, and Guy's Stone Score. Patients were considered stone-free if residual fragments were 3 mm or smaller on CT scan. RESULTS: We analyzed 329 PCNLs (left: 174; right: 155). Stones had a median size of 32 mm, 800 HU, and Guy's Stone Score of 2. Groups 1, 2, and 3 had 119, 108, and 102 patients, respectively. The 90-day complication rate was 20.4% (7.9% Clavien 3-4). Group 1 patients, with higher BMI and larger stones, had higher SFR than group 3 (89.9% vs 79.4%, Pâ¯=â¯.038), but with a significantly higher risk of complications (Pâ¯=â¯.001). Within group 1, left PCNL (7.0% vs 24.2%, Pâ¯=â¯.016) and BMI ≥30 (6.9% vs 25.0%, Pâ¯=â¯.013) carried a lower risk of chest tube insertion. There was no difference in complications between groups 2 and 3 (1.9% vs 2.9%). CONCLUSION: Upper pole access is safe and effective, particularly if done below the ribs. Supracostal access is an effective option to achieve higher stone-free rates in complex stones, while carrying a risk of significant hydrothorax, particularly on the right side and in nonobese patients.
