COMPUTER TOMOGRAPHY IN SURGICAL TREATMENT PLANNING OF CHRONIC STENOSIS OF LARYNX AND UPPER TRACHEA

Abstract

Modern endoscopic and radiologic diagnostics are complementary methods of examination of patients with chronic stenosis of the larynx and trachea, and play an important role in selection of method and surgical treatment stages planning. However, the specificity and sensitivity of CT scan for different types and different localizing stenoses, radialogical methods can't give functional evaluation of the respiratory tract. In the ENT department of PSPSMA named after I.P. Pavlov for the period from 2002 to 2013 83 patients with primary cicatricial stenosis of the larynx and the upper third of trachea of various origins (42 men, 41 women aged 17 to 73 years) were carried. Comparative analysis of CT studies and intraoperative findings was provided in each case. Thin scar membranes and scarring of the trachea above the tracheostomy tube showed varying degrees of divergence of X-ray data with clinical data and fibrolaryngoscopy. Thus, the most informative in the diagnosis of chronic stenosis of the larynx and trachea is CT with slice no more than 1 mm, and only combination of CT-scan and functional endoscopic procedures can give the most complete and accurate picture of the extent and nature of cicatricial stenosis of the larynx and upper trachea.
