It has a high incidence of occurrence in male subjects (about 80 per cent)1 and has a tendency to occur at a younger age than does cancer in other regions of the upper part of the respiratory and alimentary tracts. Statistical studies indicate that about 7 per cent of all fatal cancers in men originate in the oral region.2 Tumors of the nasal pharynx, roughly speaking, fall into three groups, namely, carcinomas, sarcomas and endotheliomas.
