Many techniques have been introduced to correct cryptotia. The previous methods are releasing the constricted cartilage and changing the mechanical fulcrum partly to the right position. However, some patients are still not satisfied with the treatment results, due to cryptotia recurrence and insufficient superior 1/3 width. This study aimed to develop a new method for completely changing the mechanical direction of constricted cartilage for correcting cryptotia.
From 2007 to 2020, twenty-four cryptotia patients were treated. During surgical reconstruction, the retroauricular skin flap was elevated, the posterior aspect of the upper auricular cartilage was completely exposed, and the abnormal insertion of the auricular intrinsic muscles detached. The sharply curved antihelical cartilage was cut and overturned, and the scalp skin flap was undermined and advanced toward the postauricular sulcus. The edge of the retroauricular scalp flap is fixed on the mastoid periosteum. The incision was closed.
Eighteen patients had unilateral cryptotia, and six had bilateral cryptotia. Relatively favorable results were obtained in the follow-up period (range, 6-48 months). There were no cases of skin necrosis, complications, or revision surgery.
The main advantages of this technique are the surgically reproducible results, and that it can be applied to most cases. The method described in this paper could potentially increase the width of the upper third of the auricle and reduce recurrence rate, while also leaving an inconspicuous scar and a satisfactory auricular contour. It is suggested that this technique could be an alternative method of cryptotia correction.

许多技术已被引入以纠正隐耳。以前的方法是释放受限制的软骨，并部分改变机械支点到正确的位置。然而，由于隐耳复发和上 1/3 宽度不足，一些患者对治疗结果仍不满意。本研究旨在开发一种新的方法，通过完全改变受限制的软骨的机械方向来纠正隐耳。
2007 年至 2020 年，24 例隐耳患者接受了治疗。在手术重建过程中，掀起耳后皮瓣，充分暴露耳上软骨的后上部分，并分离耳内固有肌的异常附着。锐弯的对耳轮软骨被切断并翻转，头皮瓣被掀起并向耳后沟推进。耳后头皮瓣的边缘固定在乳突骨膜上。关闭切口。
18 例患者为单侧隐耳，6 例为双侧隐耳。在随访期（6-48 个月）获得了相对良好的结果。没有皮肤坏死、并发症或再次手术的病例。
该技术的主要优点是手术结果可重现，且适用于大多数病例。本文描述的方法可以增加上 1/3 耳的宽度，降低复发率，同时留下不显眼的疤痕和满意的耳轮廓。建议该技术可作为隐耳矫正的替代方法。
