Nonsurgical repair of perinasal skin defects

Immediate reconstruction of full-thickness skin defects after cancer surgery is a commonly accepted surgical principle used to preserve function and minimize cosmetic deformity. Healing by secondary intention, however, offers the advantages of optimal cancer surveillance, simplified wound management, and avoidance of reconstructive procedures with their associated costs and potential complications. Accurate prediction of the course of wound healing, and thereby the final functional and cosmetic result, would allow a rational approach to selection of patients for surgical or nonsurgical repair. We observed 282 patients with full-thickness perinasal (glabella, medial canthus, dorsum, sidewall, tip, ala, philtrum, alar base, and nasolabial fold) skin defects after Mohs' surgery and documented a variety of parameters affecting wound healing, including location, depth, and size of the wound. Patients were examined at intervals, and a final determination regarding cosmesis and function was made at 6 months or later. We conclude that the most important considerations in predicting the final functional and cosmetic result include location by subunit, followed by size and depth of the wound.
