Pre-expanded Local Flaps: Optimal Choice for Repairing Defects Following Extensive Benign Tumor Resection in the Head and Face.

Background: Treating extensive benign tumors of the head and face presents a longstanding challenge, necessitating efficacy at the lesion site, and postoperative esthetic considerations for the donor area.

Objective: This study aims to explore the clinical outcomes of pre-expanded local flap reconstruction for extensive benign tumors of the head and face post resection.

Method: From March 2018 to March 2023, a total of 18 patients with extensive benign tumors of the head and face were admitted, including 13 cases of nevus, 2 cases of hemangioma, 2 cases of neurofibroma, and 1 case of verruca. Based on the location and size of the lesions, suitable local areas were selected for tissue expansion, and expanders were implanted for regular saline injections over 8 to 16 weeks. After reaching the desired expansion, resection of the head and facial tumors and local flap reconstruction were performed. Postoperatively, data on patients' information, tumor types, tumor area, expansion volume, postexpander complications, vascular condition after flap transfer, and donor site condition were collected.

Result: In this series of 18 patients, benign tumors of the head and face were completely repaired through 1 to 2 stages of tissue expansion surgeries. Postimplantation complications included hematoma in 1 case and infections in 2 cases, with one instance of expander infection leading to surgical failure. However, all other patients achieved adequate expansion, successful flap survival post-transfer, and experienced no other complications. Follow-up over 6 to 24 months showed no recurrence at the lesion sites, with flaps maintaining consistent color, texture, and thickness matching surrounding skin tissue. In addition, donor site healing was excellent, with no obvious surgical scars.

Conclusions: Pre-expanded local flap reconstruction is an ideal method for repairing extensive benign tumors of the head and face postresection.
