ADENOMA OF THE MIDDLE-EAR

Adenomas, although the most common benign tumors in the middle ear, ar e of low incidence. They may arise in a previously normal adult ear, c ausing a conductive deafness and later an aural discharge. Histologic definition may be difficult in these tumors, which are assumed to aris e from middle ear epithelium. Fairly extensive surgery may be required for their eradication. Two cases are described.
