Abstract:
Buccal mucosal graft represents the gold standard graft material for urethroplasty because of its thick epithelium and a thin lamina propria for maximal graft uptake. There is an ongoing debate whether to close the buccal graft donor site. We show a unique look at buccal donor site healing through serial pictures over a 100-day period. In this patient, the anterior half of the buccal donor site was closed at the time of harvest, allowing real-time observation of wound healing from both the closed and open aspects of the wound.
