Cryptotia correction by V-Y advancement of a temporal triangular flap was introduced in 2005. However, despite the several advantages of V-Y advancement, visible scars at the donor site are problematic. As a result, a Z-plasty technique was considered for skin deficiency in mild cases. Therefore, we introduce a new surgical scheme for cryptotia correction based on considerations of techniques and complications that arose in our clinic.
Between 2000 and 2013, 26 patients (35 cases) of cryptotia were treated. Seventeen patients had unilateral cryptotia and nine had bilateral cryptotia. Two corrective methods were used, Z-plasty or V-Y advancement, based on the severity. In mild cases, Z-plasty was used for correction and in severe cases, V-Y flap advancement was used for more skin supplement.
Follow-up periods ranged from 6 months to 1.5 years. The results obtained were relatively favorable. Nine cases of mild deformity were corrected by Z-plasty, and the other 26 cases with mild or severe deformities were corrected by V-Y advancement. In Z-plasty cases, there was one hypertrophic scar and in V-Y advancement cases, seven resulted in visible scarring and three in skin sloughing.
The main advantage of Z-plasty is a lower likelihood of visible scarring at the donor site. In mild cases, Z-plasty may be a good alternative, but in severe cases, V-Y advancement is probably the best option for more skin supplement.
2005年引入了通过颞部三角形皮瓣V-Y推进法矫正隐耳。然而，尽管V-Y推进法有诸多优点，但供区可见瘢痕仍是个问题。因此，对于轻度病例的皮肤缺损，考虑采用Z成形术。在此，我们基于对本诊所出现的技术和并发症的考量，介绍一种新的隐耳矫正手术方案。
2000年至2013年期间，对26例（35耳）隐耳患者进行了治疗。其中17例为单侧隐耳，9例为双侧隐耳。根据严重程度采用两种矫正方法，即Z成形术或V-Y推进法。轻度病例采用Z成形术矫正，重度病例采用V-Y皮瓣推进法以补充更多皮肤。
随访时间为6个月至1.5年。结果相对良好。9例轻度畸形采用Z成形术矫正，另外26例轻度或重度畸形采用V-Y推进法矫正。Z成形术病例中有1例出现增生性瘢痕，V-Y推进法病例中有7例出现可见瘢痕，3例出现皮肤脱屑。
Z成形术的主要优点是供区出现可见瘢痕的可能性较低。在轻度病例中，Z成形术可能是一个不错的选择，但在重度病例中，V-Y推进法可能是补充更多皮肤的最佳选择。
