Background: Head and neck cancer is the eighth most common cancer (1-2%) as estimated from worldwide data. Laryngeal malignancy is the second most common malignancy in head neck region worldwide. There are variety of malignant tumour arising in larynx. Carcinoma of the larynx interferes with most vital functions in the sufferers like voice, respiration and swallowing by virtue of its anatomical location, local infiltration and direct extension. Objectives: The aim of the study was to evaluate the laryngeal carcinoma: topographical distribution. Methods: This cross-sectional observational study was carried out in the Department of Otolaryngology & Head-Neck Surgery, Dhaka Medical College Hospital during January 2019 to July 2020. Purposive consecutive sampling method was used to collect data. After taking detailed history, clinical examination including indirect laryngoscopy, fiber optic layngoscopy CT scan of neck & direct laryngoscopic evaluation under general aneasthesia was done. Statistical analyses of the results were be obtained by using window-based Microsoft Excel and Statistical Packages for Social Sciences (SPSS-24). Results: Total 93 patients of different age, sex, socioeconomic status was taken. Hoarseness of voice (87.1%), dysphagia (58.1%), difficulties in breathing (57%) and neck lump (50.5%) were the common presenting complaints. 87.1% patients were smoker. Most of patients were attended with stage-III disease. Supraglottis (63.4%) was the most common site of laryngeal cancer followed by glottic (34.4%) and subglottic (2.2%). Aryepiglottic fold (23.73%) and epiglottis (20.74%) are commonly involved in supraglottic carcinoma. Single vocal cord commonly involved in glottic carcinoma. Most supraglottic carcinoma involved more than one sub site (52.34%). Supraglottic carcinoma is the most common site of laryngeal carcinoma. Combined sub site is more involved in supraglottic carcinoma. Conclusion: The topographical distribution of laryngeal carcinoma play
