Abstract: Objective To explore the clinical effect of the expanded neck flap prefabricated by superficial temporal fascia for facial resurfacing. Methods From June 2013 to March 2015, 10 patients with large facial deformity were treated with the expanded neck flap prefabricated by superficial temporal fascia. The superficial temporal fascia was separated, rotated reversely, and located beneath subcutaneous tissue of the planned expanded neck area over a tissue expander. After expansion for 5-6 months to achieve enough volume, the expected resurfacing shape was designed and raised, and an island flap based on superficial temporal fascia was harvested and rotated to resurface the facial defect. Results The expansion volume reached 400-800 ml after prefabrication. The flap size ranged from 8 cm × 9.5 cm to 14 cm × 14 cm, with an average area of 129 cm2. Ten patients were treated by this method, and there were no major complications in the expansion process, such as ischemia and necrosis. All the patients were followed up for 6 months to 1 year, there was an excellent color and texture match with surrounded facial skin. Conclusion The blood supply could increase effectively after being prefabricated with superficial temporal fascia, and more expanded skin could be harvested to repair large facial defect.
