BACKGROUND Knowledge of the influence of age on laryngeal dimensions is essential for all practitioners whose interest is the pediatric airway. Early cadaver studies documented that the larynx is conically shaped, with the apex of the cone caudally positioned at the nondistensible cricoid cartilage. These dimensions change during childhood, as the larynx assumes a more cylindrical shape. The au...

conclusions in summary, there is a lack of consensus about the use of neuromuscular blockers in patients with ibm. the authors avoided these drugs and were able to easily secure the patient’s airway and maintain adequate muscle relaxation using a balanced sevoflurane-remifentanil anesthetic. clinical trials are necessary to define the pharmacology of neuromuscular blockers in patients with ibm ...

Dysphagia in the post-cricoid region is usually found in middle-aged women and may be associated with anaemia (Jacobs and Kilpatrick, 1964). Patients with this condition sometimes have a post-cricoid web which can be seen radiologically. Although cases may occasionally be seen in women below the age of 30, no cases occurring during adolescence have been reported before in the literature. The pr...

The manoeuvre consists in temporary occlusion of the upper end of the oesophagus by backward pressure of the cricoid cartilage against the bodies of the cervical vertebrae. In the cadaver it was found that when the stomach was filled with water and firm pressure was applied to the cricoid, as described below, a steep Trendelenburg tilt did not cause regurgitation of fluid into the pharynx. More...

BACKGROUND AND PURPOSE Supracricoid horizontal partial laryngectomy (SCPL) is increasingly used to treat endolaryngeal carcinoma. However, few radiologic reports of these procedures exist. Our purpose was to evaluate the normal CT appearance of the neolarynx after surgery. METHODS SCPL includes cricohyoidopexy (CHP), cricohyoidoepiglottopexy (CHEP), and tracheocricohyoidoepiglottopexy (TCHEP)...

The tracheas of 12 patients who had undergone autopsies after percutaneous dilatational tracheot¬ omy (PDT) were analyzed macroscopically and microscopically. The puncture site of the trachea varied from just below the cricoid cartilage (two patients) to below the third ring (three patients). A fracture of one or more tracheal rings was present in 11 patients, ofwhom 2 had a fractured cri¬ coid...
