title: A case of bilateral middle-ear squamous cell carcinoma.
abstract: Only eight cases of bilateral middle-ear squamous cell carcinoma (SCC) have been reported to date. We present the case of a 75-year-old male with bilateral middle-ear SCC and review the previously reported cases. The patient was diagnosed as having moderately-differentiated SCC in the left middle ear in February 1995 and well-differentiated SCC in the right middle ear in September 1997. He initially received radiation therapy with (60)Co pendulum (64 Gy) in the left ear and was subsequently treated by Liniac irradiation (50 Gy) in the right ear. He has now been followed up at our ENT clinic for 29 months without vertigo or facial nerve palsy since the second radiation therapy. Although he has a residual tumour in the right middle ear invading the middle cranial fossa dura, no sign of recurrence has been detected in the left ear.
