OBJECTIVE The purpose of this study was to determine whether or not patients with pectus excavatum (PE) exhibit costal cartilage overgrowth compared to normal subjects. MATERIALS AND METHODS The computed tomography acquisitions of 32 patients with PE and 35 normal controls were analyzed. On axial images the length of the 4th-7th costal cartilages was measured to calculate the Haller index. Th...

Does overgrowth of costal cartilage cause pectus excavatum? A study on the lengths of ribs and costal cartilages in asymmetric patients. Jr et al. Outcome analysis of minimally invasive repair of pectus excavatum: review of 251 cases. eComment. Is overgrowth of costal cartilages the unique cause of pectus deformities? In their recent article, Park and coworkers hypothesized that 'if overgrowth ...

Abstract Purpose: Skeletal staining is a way to study the effect of many chemical or herbal substances on development of bones and cartilages in order to record the level of probable deformity.This article aimed to present a modified protocol to make all skeletal studies on laboratory animals possible. Materials and Methods: The important notes about skeletal staining were fixing by ethan...

Objective: Nasal alar retraction deformities occasionally require both soft tissue release and large cartilage grafts. The structure between the upper lateral cartilage and the lateral crus of the lower lateral cartilage has been described as fibrous tissue, intercartilaginous ligament, ligament-like arrangement or connective tissue. Despite its importance, no anatomical and histological examin...

A case of endotracheal tuberculosis with expectorations of the lateral one-third of the multiple tracheal cartilages is reported. Fibreoptic bronchoscopy revealed caseous materials and loosening of the tracheal cartilages. The patient expectorated cartilaginous material several times before and after fibreoptic bronchoscopy. In spite of the loss of tracheal cartilages, tracheal lumen was mainta...

speakerʼs phonation at two fundamental frequencies were analyzed with a 3D pattern matching method to obtain displacement and angular changes of the thyroid and cricoid cartilages. Results show displacement of the two cartilages relative to each other in 3D. The largest difference between 110 Hz and 165 Hz was found to be 1.2 mm horizontally and 0.6 mm vertically with respect to the translation...
