Abstract
MATERIALS AND METHODS
The research has been carried out with the cooperation of Department of Otorhinolaryngology of the "Ospedale S.S. Trinita" in Cagliari, on 294 patients suffering from oral malignant tumours between 1984 and 1994. This kind of disease was studied in relation to age, sex, histological type, and afterwards the examination results were compared to other researchers' studies. All the 294 patients were recorded in the operating theatre's registers. Oral malignant tumours amount to about 45% of the neoplastic systemic pathology. Use and misuse of alcohol, smoking, repeated blows resulting in pre-cancerous lesions including leukoplakia, might be considered the main causes of the origin of oral tumours.
RESULTS
Male patients (237) amount to 80.7% of the examined sample, while female ones (57) reach only 19.3%. The part most frequently involved is the tongue (97 cases, 33%), then the area of the lower lip (69 cases, 23.5%), and finally the lower part of the oral space (47 cases, 15.58%).
CONCLUSIONS
From the histological point of view, the squamous carcinoma is found more often in the tongue, in the lower oral space and in the lips, while the basal carcinoma in the lower lip rather then in the upper one. A remarkable increase in the squamous carcinoma and a grow in the areas of the tongue has been observed.
