Lateral temporal bone resection for extensive pinnal malignancy. Has anything changed in forty years?

Abstract

AbstarctThis paper offers an account of the contemporary surgical approach to advanced tumours of the external ear based on a series of 11 patients. There were eight squamous, two basal cell carcinomas and one mucoepidermoid tumour. The traditional method of excision was slightly modified by performing microsurgical dissection of the lateral part of the temporal bone rather than chisel osteotomies, and then including it en bloc with the involved soft tissues. The defect was then closed using a scalp or myocutaneous flap and this combination of otological and reconstructive expertise has proved satisfactory. Four patients are alive with no evidence of disease a mean of 4.2 (range 1.0–7.0) years from surgery: two patients who remained free of disease have subsequently died of unrelated conditions 12 and 24 months post-operatively, and in three cases death from recurrent disease occurred a mean of 1.4 (range 0.9–2.1) years after our surgery. There were two postoperative deaths. Based on the actuarial survival of 36 per cent and a successful disease clearance rate of 54 per cent, our conclusion is that the outlook of this condition has not dramatically improved since the original descriptions of the management of this problem first appeared, although intervention remains justifiable because of the potential curability and relief of symptoms.
