Abstract
To derive optimal thyroid cartilage window for medialisation thyroplasty in Indian population and comparision of the same with standard parameters including Isshiki's thyroplasty type I. Along with comparision it is also attempted to bring out difference if any, to provide a better guidelines of medialisation thyroplasty in Indian population. A total No of 52 (35 male and 17 female) cadaveric laryngeal samples (formalin fixed) taken into study. Cartilage window over thyroid lamina is created and increased gradually. Endoscopic examination of medialisation by appropriate silastic block of true vocal cord noted at each level. Relevant thyroid anatomy at window corners also taken into consideration. In Indian set up, dimensions of window required for medialisation thyroplasty are slightly lesser than the average size quoted by premier study of Isshiki when compared in male population. The window size of males which produced ideal medialisation was 12-14 mm in length and 5 mm in height. In females it was 10-11 mm in length and 4 mm in height.
