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.
为得出印度人群中用于喉内移术的最佳甲状软骨窗口，并将其与包括石木一期甲状软骨成形术在内的标准参数进行比较。除了比较之外，还试图找出其中存在的差异，以便为印度人群的喉内移术提供更好的指导方针。共选取52个（35例男性和17例女性）尸体喉样本（福尔马林固定）进行研究。在甲状软骨板上创建软骨窗口并逐渐增大。通过在每个水平用合适的硅橡胶块对真声带进行内镜检查来观察内移情况。同时也考虑窗口角处的相关甲状腺解剖结构。在印度人群中，与石木的主要研究中引用的平均尺寸相比，喉内移术所需的窗口尺寸略小。产生理想内移效果的男性窗口尺寸为长12 - 14毫米、高5毫米。女性的窗口尺寸为长10 - 11毫米、高4毫米。
