Abstract

PURPOSE
Accessory tragus is a fairly common congenital malformation and usually located at pretragal area. Surgical removal is a common treatment of accessory tragus irrespective of location and morphology. Most accessory tragi do not have depression site around them, but some do. So in those cases, simple surgical excision was not enough to promote the aesthetic facial appearance. For depression site remodeling, the excess amount of skin and cartilage need to be remained partially instead of total excision. This method can achieve the symmetric contour of pretragal area. The authors excised the epidermis and cartilaginous tissue totally and remained the dermis for reconstruction of the depression site around accessory tragus. The depression site is filled with dermal turnover flap. The purpose of this report is to present new idea to promote cosmetic result in treatment of accessory tragus containing the depression site. METHODS: Two patients had a pair of accessory tragi at pretragal area. One was a common featured accessory tragus, but the other was different. Depression site was found around accessory tragus. After epidermis and cartilaginous tissue were removed from it, dermis component was used as turnover flap for reconstruction of depression site.
RESULTS
After accessory tragus was removed and depression site was reconstructed, facial contour and cosmetic result was achieved. Complication such as flap necrosis and wound dehiscence was not observed.
CONCLUSION
The accessory tragus has variant morphology and degree of invasive depth. And some has a depression site around them. In those cases, simple surgical removal results in morphological distorsion and do not promote facial symmetry. The authors suggest dermal turnover flap as reconstruction method of the depression site. This method improves both surgical outcome and cosmetic result.
