The degree of lingual tonsil hypertrophy was examined in 197 patients by lateral radiographs of the throat. Two parameters were designed on the radiograph: 1) the relationship between the lingual tonsil and the epiglottis, which was classified into three types, free (no touching), tip touching and total touching; 2) the percentage of the pharyngeal cavity occupied by the lingual tonsil. Patients were divided into two groups: with or without abnormal sensation in the throat. In those without abnormal sensation, tip touching and total touching types were found in only 18.1 and 7.2%, respectively. Of those with abnormal sensation more than 50% had tip or total touching tonsils. In females with abnormal sensation in the throat 42.4±14.5% of the pharyngeal cavity was occupied by the lingual tonsils, while in those without abnormal sensation 35.3±10.6% was occupied by the lingual tonsils. The figure was a significant difference. In the males no significant difference was found between the groups with and without abnormal sensation. It is concluded that the touching of the epiglottis and the lingual tonsil and the hypertrophy of the lingual tonsil, especially in females, may play a role in the incidence of abnormal sensation of the throat.
