Scalp Composite Tissue Transplantation for Repairing Upper Lip Defect: A Feasible Clinical Study.

Abstract

The repair of upper lip defects is difficult and can result in asymmetry. The authors have developed a postauricular scalp composite tissue for the repair of upper lip defects. Herein, the authors, present the feasibility of scalp composite tissue grafts for repairing of upper lip defects. The authors conducted a retrospective study of 10 patients who underwent scalp composite tissue transplantation for upper lip repair. The surgical procedure consisted of the excision of skin lesions or scar tissue from the upper lip to prepare the recipient area, and then the scalp composite tissue was excised behind the ear and transplanted to the upper lip defect. The authors reviewed the photographs and clinical notes of these patients. The patients' self-reported satisfaction with the repair effect was assessed. Tissue sections and hematoxylin and eosin staining of the scalp composite tissues were performed. All patients successfully underwent lesion resection and scalp composite tissue transplantation to repair the wound. There was no necrosis of the scalp composite tissue in the early postoperative period. The lip wound healed completely within 2 weeks. The mean follow-up time was 16 months, ranging from 12 to 20 months. Histologic sections and hematoxylin and eosin staining showed that the scalp composite tissue had abundant capillaries and dense fibrous connective tissue. All 10 patients were satisfied with the clinical effect of the procedure. Scalp composite tissue transplantation is a viable method for repairing upper lip defects. The special histomorphological characteristics of the scalp provide the basis for clinical application. IV.
