Abstract
The authors report four cases of cancer of the external auditory meatus.
One of the cases involved the cartilaginous portion and the other three cases the bony portion in the external auditory meatus.
Two cases had a history of radical mastoidectomy and one had a habit of ear scratching.
In the three cases with cancer in the bony portion, chemotherapy by arterial infusion was performed prior to surgical treatment. In a case that showed some response to the chemotherapy by arterial infusion, although the area of dissection was reduced, a recurrence was observed. In the other cases where dissection was made en block inducing the cartilaginousand bony portions of the external auditory meatus and the middle ear, no recurrence was observed.
The authors concluded that even in cases where preoperative radiation therapy and chemotherapy by arterial infusion were found to be effective, dissection should include a wider area in order to prevent recurrence.
