Cryptotia Repair Using a Modified V-Y Advancement Flap with Helix Rounding Technique.

[BACKGROUND] Cryptotia is a common congenital auricular malformation seen in Asian people. To date, multiple surgical procedures have been described for correcting cryptotia. However, the deformity often recurs, presenting as an unclear auriculotemporal sulcus and a malformed helix. The present study aimed to introduce a novel surgical approach to obtain a stable and aesthetic auricular correction in cryptotia patients and to acquire an understanding toward improved surgical management of cryptotia.

[METHODS] Twenty-four cryptotia patients (28 ears), who were operated between April 2018 and November 2021, were included in this study. All patients underwent surgical correction for cryptotia using a modified V-Y advancement flap with helix rounding technique, performed by a senior surgeon.

[RESULTS] Patients were followed for an average period of 9.4 months (6 to 18 months). Twenty-one patients (87.5%) were satisfied, three (12.5%) were partially satisfied, and none were unsatisfied. Most patients experienced temporary edema as a postsurgical complication, which resulted in a swollen auricle appearance lasting for three to four weeks postoperatively. One patient experienced skin necrosis in one ear on the anterior portion of the upper helix and this was solved by skin grafting.

[CONCLUSIONS] The method of surgical correction utilizing a modified V-Y advancement flap with helix rounding technique proved to be a reliable option in cryptotia patients. It can provide stable aesthetic results after cryptotia correction in clinical practice.
