We herein present a technique of using the umbilical stalk for reconstruction of the external auditory meatus. A 49-year-old female presented with locally aggressive melanoma affecting her mastoid region. She underwent radical excision including the skin and soft tissues around the external ear with simultaneous lymph node clearance. The resultant defect measured 15 cm × 8 cm in diameter and was 2.5 cm deep. This was reconstructed with a similarly sized microvascular paraumbilical perforator flap that included the umbilical stalk. In the post-operative course there was complete flap survival but a prolonged wound dehiscence near the auditory meatus that required revision surgery. At 15-months follow-up, the patient was melanoma-free and the auditory meatus was patent. Hearing was also preserved. The umbilical stalk is one of the few skin covered tubed structures in the human body that may be used without major donor morbidity to "replace like with like," the auditory channel.
我们在此介绍一种利用脐带来重建外耳道的技术。一名49岁女性,患有侵犯乳突区的局部侵袭性黑色素瘤。她接受了根治性切除,包括外耳周围的皮肤和软组织,并同时进行了淋巴结清扫。术后形成的缺损直径为15厘米×8厘米,深2.5厘米。使用一块大小相似的包含脐带的微血管脐旁穿支皮瓣进行了重建。术后过程中皮瓣完全存活,但外耳道附近伤口裂开时间延长,需要进行修复手术。在15个月的随访中,患者无黑色素瘤复发,外耳道通畅,听力也得以保留。脐带是人体中少数几个有皮肤覆盖的管状结构之一,可以在供体无严重并发症的情况下用于“以类似结构替代类似结构”,即替代听觉通道。
