Article Abstract
Objective: Critical components of the nasal endoscopic examination have not been definitively established for either the normal examination or for clinical disorders. This study aimed to identify concordance among rhinologists regarding the importance of examination findings for various nasal pathologies.
Study Design: A consortium of 19 expert rhinologists across the United States was asked to rank the importance of findings on nasal endoscopy for 5 different sinonasal symptom presentations.
Setting: An online questionnaire was distributed in July 2023.
Methods: The questionnaire utilized JotForm® software and featured 5 cases with a set of 4 identical questions per case, each covering a common indication for nasal endoscopy. Rankings were synthesized into Normalized Attention Scores (NASs) and Weighted Normalized Attention Scores (W-NASs) to represent the perceived importance of each feature, scaled from 0 to 1.
Results: General concordance was found for examination findings on nasal endoscopy within each case. The perceived features of importance differed between cases based on clinical presentation. For instance, in evaluating postnasal drip, the middle meatus was selected as the most important structure to examine (NAS, 0.73), with mucus selected as the most important abnormal finding (W-NAS, 0.66). The primary feature of interest for mucus was whether it was purulent or not (W-NAS, 0.67). Similar analyses were performed for features in each case.
Conclusion: The implicit framework existing among rhinologists may help standardize examinations and improve diagnostic accuracy, augment the instruction of trainees, and inform the development of artificially intelligent algorithms to enhance clinical decision-making during nasal endoscopy.

Novel hypoglossal stimulation markedly improves airflow and airway collapsibility in OSA.
Chest
September 2025
Flinders Health and Medical Research Institute/Adelaide Institute for Sleep Health, Flinders University, Bedford Park, South Australia, Australia.
Background: Hypoglossal nerve stimulation (HNS) to treat obstructive sleep apnea (OSA) currently requires placement of a cuff or 'saddle' electrode around or adjacent to the hypoglossal nerve(s). Limitations for this therapy include cost, invasiveness, and variable efficacy.
Research Question: Can HNS applied via percutaneous implantation of a linear, multi-pair electrode array restore airflow to airway narrowing and/or obstruction, and improve airway collapsibility in people with OSA?
Study Design And Methods: Participants with OSA undergoing drug induced sleep endoscopy with propofol were instrumented with an epiglottic pressure catheter, nasal mask and pneumotachograph.
Retrospective Study of Pediatric Sinonasal Tumors in a Tertiary Hospital Setting.

BACKGROUND Pediatric sinonasal tumors are rare, accounting for about 4% of all pediatric head and neck neoplasms. Due to their nonspecific symptoms such as nasal obstruction, epistaxis, and facial pain, these tumors often present diagnostic challenges and lead to delays in managment. Early and accurate diagnosis is crucial to optimize clinical outcomes.

Introduction: Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome that is characterized by hypophosphatemia resulting from the leakage of renal phosphate. Due to its diverse and nonspecific clinical manifestations, the diagnosis is often delayed.
Case Report: We present the rare case of a 33-year-old man with TIO who was presented with chronic bilateral hip joint pain and was initially misdiagnosed with osteonecrosis of the femoral head.

With the ongoing advancement of nasal endoscopic surgical techniques, rhinologists are increasingly tasked with addressing not only nasal sinus lesions but also exploring transnasal approaches for managing lesions involving the eyes and skull base. The complex anatomy of the nose, adjacent to the skull base superiorly and the medial orbital walls bilaterally, supports the use of artificial materials during surgical procedures for repair or reconstruction. Furthermore, artificial materials aid in the regeneration of nasal mucous membranes, promoting healing.
