A Strategy for Integrative Reconstruction of Midface Defects Using an Extended Forehead Flap.

Background: Midface reconstruction is challenging because the structures and deformities involved are complicated. In this study, we present a strategy for integrally reconstructing nasal and midface defects, including hair-bearing defects, using extended forehead-expanded flaps. Methods: From 2015 to 2018, a total of 22 patients with midface defects underwent reconstruction with extended forehead-expanded flaps. The far end of the expanded flap, which included scalp hair, was used to cover the upper lip defect (Type 1). In cases with large perioral defects (Type 2), we designed two separate supratrochlear artery flaps, one with a shorter pedicle for nasal reconstruction and the other with a longer pedicle for partial reconstruction. The pedicle of the longer flap was saved for upper lip recovery after pedicle interruption. Results: Among the 22 patients (13 male and 9 female), 17 were caused by burns and 5 by trauma. Nineteen patients had Type 1 defects, and three had Type 2 defects. The average postoperative follow-up was 17.6 ± 4.3 months. Patient satisfaction was excellent in most patients. Conclusions: Our extended forehead flap strategy can achieve aesthetic recovery of nasal and perioral defects with a single expansion treatment. The expanded flap can be flexibly designed to fit diverse midface defects.
