    Abstract: Subglottic stenosis (SGS) represents a constellation of diverse pathologic processes that ultimately lead to narrowing of the subglottic region and can produce significant morbidity. Existing endoscopic and radiographic assessments may not be consistent in practice. Methods: Severity of stenosis was evaluated and reported using the Cotton-Myer classification system from 33 endoscopic procedures from 32 unique subjects. Radiographic imaging within the preceding 3 month period was subsequently reviewed and narrowing was measured by a blinded radiologist. Degree of stenosis was reported as a percentage in 30 out of 33 endoscopic evaluations and subsequently compared to radiographically determined percentage of stenosis. Statistical analyzes were conducted to evaluate concordance between endoscopic and radiographic assessments. Results: About 45.5% (15/33) of the evaluations were in agreement using Cotton-Myer scoring, while 27.3% (9/33) were discrepant by 1 grade and 27.3% (9/33) by 2 grades. Correlation of degree of stenosis as a percentage using Spearman (coefficient: 0.233, P-value: .214) and Pearson (coefficient: 0.138, P-value: .466) methods demonstrated very weak relationships. Radiographic scoring did not predict endoscopic classification to a significant degree using mixed effects regression. Conclusions: Radiographic and endoscopic grading of subglottic stenosis may not be reliably concordant in practice.

    Characterization of Trapezial Pommel in Relation to Radiographic and Wear Patterns in Carpometacarpal Osteoarthritis
    SAGE Publications ; 2022

    Abstract: Trapezial pommel, or ulnar osteophyte positioned at the vertex of the saddle-shaped facet, is a consistent structural appearance in osteoarthritis (OA) of the first carpometacarpal. This study investigates its relation to radiographic measures (modified Eaton staging and thumb OA [ThOA] index) and wear patterns (trapezial surface morphology and cartilaginous eburnation). Methods: In all, 137 whole trapezia were explanted from 116 patients and evaluated for Eaton staging, morphology (saddle, cirque, or dish), and eburnation (degree of cartilaginous effacement) of the articular surface of the trapezium. In total, 131 Robert’s views and 126 stress views were reviewed by 2 blinded senior surgeons for ThOA index and pommel size. Statistical analyses included Spearman correlation and linear regression. Results: Standardized pommel size achieved good intrarater reliability (correlation coefficient: 0.80-0.98) and moderate interrater reliability (correlation coefficient: 0.60-0.67). The ThOA index and pommel size were significantly correlated across Robert’s ( r s = 0.51) and stress views ( r s = 0.64). The ThOA index better distinguished between stages compared with pommel size. All the radiographic measures inversely correlated with preserved cartilage and varied across morphologies. Pommel size differed significantly between dish and saddle, and the ThOA index was significantly different between all morphologies when using stress views. Conclusions: We reliably quantified the pommel feature and demonstrated significant correlations with other radiographic and topologic measures of arthritic disease. If future studies can demonstrate that the pommel is a pathogenic process in ThOA and its correction can curb disease progression, the identification of the pommel feature may help guide targeted intervention.
