Association Between Bitter Taste Receptor Phenotype and Clinical Outcomes Among Patients With COVID-19.

Importance: Bitter taste receptors (T2Rs) have been implicated in sinonasal innate immunity, and genetic variation conferred by allelic variants in T2R genes is associated with variation in upper respiratory tract pathogen susceptibility, symptoms, and outcomes. Bitter taste receptor phenotype appears to be associated with the clinical course and symptom duration of SARS-CoV-2 infection.

Objective: To evaluate the association between T2R phenotype and patient clinical course after infection with SARS-CoV-2.

Costal Cartilage Lateral Crural Strut Graft for Correction of External Nasal Valve Dysfunction in Primary and Revision Rhinoplasty.

Objective: To evaluate and compare the costal cartilage lateral crural strut graft's (LCSG) ability to support a weak lateral crus in patients with external nasal valve dysfunction (EVD) undergoing primary versus revision functional rhinoplasty.

Methods: This is a prospective cohort study of 26 patients (mean [SD]: 40.23 [6.

Variability of the Anterior Ethmoid Artery in Endoscopic Sinus Surgery.

Introduction: The anterior ethmoidal artery (AEA) demonstrates anatomic variability relative to its descent from the anterior skull base. Our study's objective was to assess for correlation of AEA descent and laterality, in addition to correlation of AEA descent and the presence of supraorbital ethmoid cells (SOEC) and concha bullosae (CB).

Method: A retrospective study was performed at a tertiary rhinology center from January 2019 to January 2020.

Rhinologic Procedures in the Era of COVID-19: Health-care Provider Protection Protocol.

Introduction: SARS-CoV-2 has been identified as the pathogen causing the outbreak of Coronavirus Disease 2019 (COVID-19) that started in Wuhan, China, in December 2019. SARS-CoV-2 has human-to-human transmission ability and universally contagious to all populations. The main transmission patterns are respiratory droplets transmission and contact transmission.

Impact of Draf III, Draf IIb, and Draf IIa frontal sinus surgery on nasal irrigation distribution.

Background: Delivery of topical pharmacotherapy to the paranasal sinuses remains integral to the management of chronic rhinosinusitis. The frontal sinus remains a difficult access site for irrigations, often limited by its position relative to the nostril and ethmoid sinus. In view of the previous demonstration of improved frontal sinus irrigation with Draf III vs Draf IIa, in this work we sought to evaluate topical access of Draf IIb relative to Draf IIa and Draf III modification of the frontal sinus outflow tract.
