INTRODUCTION, MATERIAL AND METHODS, AIM OF THE STUDY: Evaluation of the methods and results of treatment of 19 cases of malignant tumors of the external auditory meatus and/or temporal bone was performed.

RESULTS: In 10 cases planoepithelial carcinoma was diagnosed; in 7 cases basocellulare carcinoma; in 1 case rhabdomyosarcoma; and in 1 case malignant peripheral nerve sheath tumor were histopathologically established. In stage T1 were 8 cases, in T2 - 7, in T3 - 1 and in T4 3 patients were stated based upon clinical and radiological (HRCT and MRI) examination. Three patients in T4 stage were qualified to palliative therapy. In 2 cases radical mastoidectomy was performed, 8 patients underwent partial temporal bone resection. In 6 cases removal of cartilaginous and osseous external auditory meatus was done. In 9 cases local recurrence of tumor was observed during 2 years after surgery. The last 7 cases are under oncological observation.

CONCLUSIONS: In conclusion we stressed that patients with malignant tumors of this region are treated in late stages of the disease; it is a main cause of poor diagnosis.
