Background:
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.
Methods:
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.
Results:
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.
Conclusion:
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.
