The present paper deals with the qualitative and quantitative distribution of tumour patients treated at the Budapest Clinic Maxillofacial Surgery in the east 30 years. These patients suffered from: odontogenic tumours, 135 cases: non-odontogenic benign tumours, 1219; and malignant tumours, 1238. Compared to previous data, the present findings evidence the upward trend of the frequency of tumours and of the malignant ones among them.
