Supraglottic cancer is one of the common head and neck cancer (excluding skin). The incidence rates for laryngeal cancer in Central Europe are among the highest in the world. Approximately 87% of laryngeal cancer cases are attributable to tobacco use, of which 75% and12% are due to current and past smoking, respectively. The occurrence of 12,250 new cases/yr with Male:Female ratio of 4: 1 and it occurs at the peak age of 6th and 7th decades of life.We had conducted a retrospective study on a total of 147 patients of either sex in one year. In these patients, supraglottic cancer was confirmed by histopathological examination of the tissue obtained by direct laryngoscopy and biopsy in the operation theatre.Out of 147 patients, 138 (93.8%) were males and 9 (6.2%) were females. Majority of patients were in the age group of 51–60yrs i.e. 56 patients (38.09%). Smoking was a major risk factor seen in all patients (100%).There was no statistical difference between the two sexes (p>0.05).
