Gliederung

Text

Carcinoma of the external auditory canal and the middle ear is a rather rare event. It is especially seen in patients with chronic ear disease and according inflammatory alteration of the epithelial surface. An occasional occurrence of malignant tumors after middle ear operations is described in the literature.

A 65 years old patient with a chronic otorrhoe had been treated with local antibiotics for weeks without improvement. A radical ear operation (canal wall down) with construction a large mastoid cavity had been performed 40 years ago. Suspecting an infectious reason with involvement of the outer ear canal a revision operation was planned. After operative resection of some granulative tissue the typical picture of malignant tissue could be seen under the operation microscope. Via fast histological investigation a squamous-cell carcinoma had been diagnosed. After extensive staging (N2b, M0) a partial resection of the temporal bone, a lateral parotidectomy and a functional neck dissection had been performed. It was followed by adjuvant radiotherapy after completed healing of the sore.

Carcinoma of the temporal bone and the middle ear are tumours considered to have poor prognosis. It depends on extension and stage and for that reason on time of diagnosis.

In this special case a conservative treatment is a fatal prolongation of the diagnostic process. In case of long lasting, therapy-resistant otorrhoea malignant neoplasm should be considered and ruled out by an exploratory excision.
