In the repair of prominent ear deformities, the main objectives are to recreate the antihelical fold, reduce projection in patients with a large concha, and normalize the distance between the ear and the cranium. This study evaluated the efficacy of the adipo-perichondrial flap-assisted posterior auricular muscle complex (PAMC) flap technique, which involves a new approach to the repair of prominent ear deformities.
A medially based PAMC flap and a laterally based adipo-perichondrial flap were elevated in 22 patients with prominent ear deformities. In order to shape the ear, the PAMC flap was sutured to the transition zone between the helix and antihelix, and the adipo-perichondrial flap to the periosteum of the mastoid bone. The ear-cranium distances were measured preoperatively and at postoperative first and sixth months.
Thirteen patients were female and 9 were male. The mean age of the patients was 19.4 years, and the mean follow-up period was 10.6 months. The ear-cranium distance significantly decreased in the postoperative first-month and sixth-month evaluations compared to the preoperative values (P < .05). No relapse, suture exposition, hematoma, keloid scar, or infection was observed.
Posterior auricular muscle complex is a strong anatomical structure that includes the trapezius muscle, occipital muscle, extrinsic ear muscles, temporal fascia, and sternocleidomastoid fascia. By elevating this structure as a flap and combining it with an adipo-perichondrial flap, successful results can be achieved in the repair of prominent ear deformities, which prevents relapses and maintains the shape of the ear in the long term.
在修复招风耳畸形时，主要目标是重建对耳轮，减少大耳甲腔患者的突出度，并使耳与颅骨之间的距离正常化。本研究评估了脂肪软骨膜瓣辅助耳后肌复合（PAMC）瓣技术的疗效，该技术涉及修复招风耳畸形的新方法。
在 22 例招风耳畸形患者中，我们采用了一种基于内侧的 PAMC 皮瓣和一种基于外侧的脂肪软骨膜瓣。为了塑造耳朵，我们将 PAMC 皮瓣缝合到耳轮和对耳轮之间的过渡区，将脂肪软骨膜瓣缝合到乳突骨的骨膜上。术前和术后第一个月和第六个月测量耳颅距离。
13 例患者为女性，9 例为男性。患者的平均年龄为 19.4 岁，平均随访时间为 10.6 个月。与术前相比，术后第一个月和第六个月的耳颅距离显著减小（P<0.05）。未观察到复发、缝线暴露、血肿、瘢痕疙瘩或感染。
耳后肌复合是一种强大的解剖结构，包括斜方肌、枕肌、耳外肌、颞筋膜和胸锁乳突筋膜。通过将该结构作为皮瓣抬起，并与脂肪软骨膜瓣结合，可成功修复招风耳畸形，防止复发，并长期保持耳朵的形状。
