The malignant tumors of the external auditory canal often invade the middle ear area through the narrow canal, so it is difficult to determine the surgical excisional margin. A patient undergoing external auditory canal reconstruction following excision of a squamous cell carcinoma using a chondrocutaneous flap and fiberscope-assisted preoperative and postoperative diagnoses are described. We obtained good patency of the canal postoperatively. This technique is quite simple and easy to use. We believe fiberscope-assisted surgery is useful for extracting lesions in small areas. In the future, its application will extend to the area of plastic surgery.
外耳道恶性肿瘤常通过狭窄的外耳道侵犯中耳区域，因此难以确定手术切缘。本文描述了1例使用软骨皮瓣切除鳞状细胞癌后进行外耳道重建的患者，以及术前和术后纤维内镜辅助诊断的情况。术后我们获得了良好的外耳道通畅性。该技术非常简单且易于使用。我们认为纤维内镜辅助手术有助于切除小区域的病变。未来，其应用将扩展到整形手术领域。
