Microskin Grafting for Vitiligo of the Auricle

Vitiligo is an acquired discoloration of skin and mucous membrane of great cosmetic importance affecting 1-4% of the world’s population. The most common variety observed was vitiligo vulgaris (66%), followed by acro-facial (11%), mucosal (10%), focal (7%), segmental (4%), and universalis (2%). Seventynine percent of patients had more than 10% body surface area involvement, 80% had involvement of exposed areas, and 67% had an actively progressive disease.The surgical management of the vitiligo of the auricle is a challenging task due to its uneven surfaces which are difficult to reach for surgical tools. The authors have noticed that most of the patients of vitiligo of the concha of the auricle are of vitiligo vulgaris variety and very few of focal or segmental type. Vitiligo vulgaris is a type of non-segmental, bilateral and usually symmetrical vitiligo while focal vitiligo is a localized form of vitiligo.

Microskin grafting is a tissue grafting technique. For this, we need a small piece of thin split-thickness skin graft (STSG-T) or ultrathin split-thickness skin graft (STSG-UT). The authors prefer to harvest a small graft from the post-auricular area for the surgical management of vitiligo of the Concha.The harvesting of the graft from other hidden areas like gluteal fold, gluteal region or thigh may lead to hindering the patients’ movements and so, are preferably avoided by the authors.
