Cricoarytenoid joint: histological changes during aging

Aging histological changes in the cartilages of the cricoarytenoid joint1

Purpose: Analysis of ossification, bone marrow formation, perichondrium thickness, muscle fibers, collagen fibers and elastic fibers quantities of cricoid and arytenoid cartilages. Design: Correlation morphologic study. Methods: Twenty-four cricoarytenoid joints were obtained from Caucasian male fresh cadavers divided into three groups with eight specimens in each: group I – adolescents, from 1...

Changes in the cricoarytenoid joint induced by intubation in neonates.

OBJECTIVE To characterize the histopathologic characteristics of the cricoarytenoid joint (CAJ) as a means to understand the mechanisms of vocal cord fixation in children after prolonged intubation. DESIGN Histologic analysis of laryngeal specimens obtained from infants who had died secondary to various causes and who had been intubated from 1 to 30 days. MAIN OUTCOME MEASURE Histopathologi...

Synovial tissue morphology of the cricoarytenoid joint in the elderly: a histological comparison with the cricothyroid joint.

We compared the age-related morphology of the cricothyroid (CT) joint with that of the cricoarytenoid (CA) joint using 18 specimens from elderly cadavers in terms of their elastic fiber contents as well as the cells composing the joint capsule and synovial tissues. In contrast to an almost flat-flat interface in the CT joint, the CA joint was similar to a saddle joint. The CA joint capsule was ...

Surgical-anatomical Aspect of the Cricoarytenoid Joint

An often overlooked joint in rheumatoid arthritis: cricoarytenoid joint

Purpose: The aim of this study was to assess the prevalence of laryngeal involvement in RA patients, and thus, to increase the awareness of this condition among rheumatologists and otolaryngologists. Method: A total of 82 subjects with non-smoker, consisting of 42 patients with RA and 40 non-RA patients in the control group, were enrolled in this study. The laryngeal symptoms such as dysphonia,...
