A cross sectional study of 154 cases of laryngeal carcinoma was carried out in the in-patient department of Bangabandhu Sheikh Mujib Medical University and Dhaka Medical College during the period of two years with an aim to find out the frequency of site and subsite involvement of carcinoma of the larynx. The age range is 33-80 years and the over all male to female ratio is 29.8:1. Smoking and chewing habit are the most important associated factors. Majority of growths are found to be exophytic and most of the patients present at advanced stage.
