RESUMO
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.
