Resection of skin cancers of the conchal fossa and anti-helical rim presents a challenging reconstructive problem. A full thickness skin graft is often used following excision of the cartilage underlying the lesion. Colour mismatch, a contour defect and a donor site scar are potential drawbacks to this method of reconstruction. The postauricular trap door flap offers a superior option for these defects.
This study aims to assess the reliability and outcomes of the trap door flap for defects of the anterior surface of the pinna.
A retrospective review of all trap door flaps carried out in Galway University Hospital was carried out. Charts were reviewed in order to examine operative notes and assess for any complications and length of follow up.
45 Patients were operated on by a single surgeon. The age range was 61-93 years. The majority of lesions excised were from the conchal area with 6 defects predominantly involving the scapha. No partial or complete flap loss occurred. 2 patients required further excision due to an incomplete margin and a local recurrence respectively. Follow up ranged from 3 months to 4 years with excellent cosmetic results were achieved in all cases with no scar issues at the flap or donor sites.
The trap door flap is an excellent method of conchal reconstruction. It is reliable and reproducible with no flap loss demonstrated in our series of 45 patients. Large defects can be reconstructed with this flap and the cosmetic result in terms of colour and contour, as well as a hidden donor site scar, make this a superior option to a full thickness skin graft.
切除耳甲腔和对耳轮的皮肤癌会带来具有挑战性的重建问题。在切除病变下方的软骨后，通常会使用全厚皮片移植。颜色不匹配、轮廓缺陷和供区瘢痕是这种重建方法的潜在缺点。耳后活瓣皮瓣为此类缺陷提供了更好的选择。
本研究旨在评估耳后活瓣皮瓣用于修复耳甲前部缺陷的可靠性和结果。
对戈尔韦大学医院进行的所有耳后活瓣皮瓣手术进行了回顾性研究。查阅图表以检查手术记录并评估任何并发症和随访时间。
45 例患者由一名外科医生进行手术。年龄范围为 61-93 岁。切除的大多数病变位于耳甲区域，其中 6 例主要涉及耳甲腔。没有发生部分或完全皮瓣坏死。2 例患者因切缘不完整和局部复发分别需要进一步切除。随访时间为 3 个月至 4 年，所有病例均获得了极好的美容效果，皮瓣和供区均无瘢痕问题。
耳后活瓣皮瓣是一种极好的耳甲重建方法。在我们的 45 例患者系列中，它是可靠且可重复的，没有皮瓣坏死的情况。该皮瓣可重建较大的缺陷，并且在颜色和轮廓方面的美容效果以及隐藏的供区瘢痕，使其成为全厚皮片的更好选择。
