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.
迄今为止，仅报告了8例双侧中耳鳞状细胞癌（SCC）。我们报告一例75岁男性双侧中耳SCC病例，并回顾先前报道的病例。该患者于1995年2月被诊断为左中耳中度分化SCC，1997年9月被诊断为右中耳高分化SCC。他最初左耳接受（60）钴摆位放疗（64 Gy），随后右耳接受直线加速器放疗（50 Gy）。自第二次放疗以来，他在我们的耳鼻喉科门诊随访了29个月，无眩晕或面神经麻痹。虽然他右中耳有残留肿瘤侵犯中颅窝硬脑膜，但左耳未发现复发迹象。
