 The temporal bone in a case of squamous cell carcinoma, originating in the external auditory canal and extending into the middle ear and mastoid, was studied histopathologically.

 A 32-year-old male with the advanced cancer of T3N0M0 was treated with the combination of Linac irradiation and radical operation of the middle ear, but lie died of pulmonary metastasis and purulent meningitis.

 The temporal bone findings revealed the extensive destruction of the external and middle ears with tumorous infiltration and osteoradionecrosis. The inner ear showed pictures of purulent labyrinthitis and severe atrophy of the membranous labyrinth due to irradiation. In spite of high dose of irradiation, the tumor mass remained in the internal auditory canal and pyramidal apical cells.

 From these, it is suggested that the control of squamous cell carcinoma, once extending into the middle ear and mastoid, is difficult with irradiation alone, and the subtotal resection of the temporal bone may be required for radical cure.
