Histopathology of Recalcitrant Maxillary Sinusitis Necessitating Endoscopic Medial Maxillectomy.

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.

Histopathology of Allergic Fungal Rhinosinusitis Versus Chronic Rhinosinusitis with Nasal Polyps.

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.

Histopathologic features of biologic therapy nonresponders in chronic rhinosinusitis with nasal polyposis.

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.

Computed Tomography Imaging Patterns of Sinonasal Inverted Papillomas: Comparison of Primary and Recurrent Disease.

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.

The effect of head of bed elevation on upper airway collapsibility during drug-induced sleep endoscopy.

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.

Histopathologic Features of Chronic Rhinosinusitis in Diabetic Patients.

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.

Patient safety and quality improvements in parotid surgery.

Parotidectomy is the mainstay treatment for tumors of the parotid gland. In an effort to improve clinical outcomes, several modern surgical techniques and perioperative interventions have been evaluated and refined. This review discusses current and actively debated perioperative interventions aimed at improving patient safety and the quality of parotidectomy.

Laryngeal Chondrosarcoma Characteristics and Survival Analysis in the National Cancer Database.

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).

Analysis of Sinus Balloon Catheter Dilation Providers Based on Medicare Provider Utilization and Payment Data.

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.

Upper Pole Access for Prone Percutaneous Nephrolithotomy: Advantage or Risk?

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).

Trends in urinary calculi composition from 2005 to 2015: a single tertiary center study.

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.
