OBJECTIVE To measure the working dimensions of the cricothyroid membrane in the adult south Indian population and to establish the association between the working dimensions and the appropriate endotracheal tube size for the purpose of cricothyroidotomy. METHODS Cross-sectional evaluation of 50 fresh adult autopsy cases (35 men, 15 women) in a medical university teaching hospital in South Ind...

Chondrosarcoma (CS) of the larynx was first described in 1935. Cartilaginous tumours of the larynx are largely rare and there is little literature concerning them. Laryngeal CS manifest with a different pathological behaviour to other malignancies of the larynx and as such the treatment of these neoplasias are different. The purpose of this review is to present a detailed report of the laryngea...

Cartilage tissue engineering, with in vitro expansion of autologus chondrocytes, is a promising technique for tissue regeneration and is a new potential strategy to prevent and/or treat cartilage damage (e.g., osteoarthritis). The aim of this study was (i) to investigate and compare the effects of new biotechnological chondroitin (BC) and a commercial extractive chondroitin sulfate (CS) on huma...

Cricoid pressure is considered an integral part of patient safety in rapid sequence tracheal intubation and emergency airway management. Cricoid pressure is applied to prevent the regurgitation of gastric contents into the pharynx and subsequent aspiration into the pulmonary tree. This review analyzes the published evidence supporting cricoid pressure, along with potential problems, including i...

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...

OBJECTIVE To review our experience using posterior cricoid grafts to manage pediatric patients with isolated posterior glottic stenosis (PGS). DESIGN Retrospective review over a 12-year period. SETTING Tertiary care pediatric hospital. PATIENTS All patients with isolated PGS treated between 1990 and 2002, in whom PGS was the dominant airway lesion and laryngotracheoplasty was required. Pa...

We have studied 40 patients to see if cricoid pressure affects the success rate of ventilation through, and the position of, the laryngeal mask and subsequent fiberscope-aided tracheal intubation. Adequate ventilation of the lungs was produced through the laryngeal mask in 19 of 20 patients in the control group, but in only 10 of 20 patients in the cricoid pressure group (P < 0.002). The laryng...

PURPOSE Cricoid pressure is commonly used during rapid sequence induction and intubation to minimize the risk of aspiration. The objective of the study was to evaluate the ease of fibreoptic (WuScope System(TM)) intubation in anesthetized adults receiving cricoid pressure. METHODS The intubation difficulty scale (IDS) was used to measure tracheal intubation difficulties in 33 patients undergo...

OBJECTIVES To demonstrate a novel approach to cricoarytenoid joint (CAJ) injections. STUDY DESIGN Anatomic feasibility study. METHODS Five human cadaveric larynges providing 10 CAJ s were used to obtain trajectory measurements of a 27-gauge 1½-inch needle placed between the CAJ capsule and the contralateral cricothyroid membrane. Ten additional larynges providing 20 CAJ s were then used to ...
