Extensive Facial Reconstruction Using Thickness-controlled Perforator Free Flaps

Although small and medium facial defects can be reconstructed with local flaps to ensure skin color and texture matching, extensive facial defects require the application of free flaps, including perforator free flaps. We hereby propose a personalized strategy for facial reconstruction to overcome these limitations, based on the use of free flaps accompanied by local flaps and thickness-controlled perforator flap concept, for extensive facial defects.

A series of consecutive facial reconstructions were performed from 2006 to 2016 in the Plastic and Reconstructive Surgery Department of our institution. Only extensive facial defects greater than 40 cm² were included in this study.

A total of 323 patients underwent reconstruction using free flaps with or without local flaps, from November 2005 to March 2019. Of these, 79 extensive facial surface reconstruction cases were analyzed retrospectively. The size of the defects, their areas (upper, middle, or lower third of the face), and the method of reconstruction were analyzed. This led to the development of a personalized reconstruction procedure for extensive facial defects. These extensive facial reconstruction cases included 24 defects of the upper third of the face, 43 cases of the middle third, and 12 of the lower third. Four cases addressed the middle and lower thirds simultaneously.

The facial surface reconstruction strategy I suggest in this study is based on the flap selection, thickness-controlled perforator flap elevation, and combination of local and free flaps. We expect this procedure will improve the treatment and resolution of extensive facial defects.
