Application of free serratus anterior muscle-fascial composite tissue flap and facial lipofilling in repairing progressive hemifacial atrophy

Abstract

IntroductionProgressive hemifacial atrophy (PHA) is a nonnegligible disease, and its treatment currently lacks consensus. We aim to conduct an analysis of PHA patients to summarize the postoperative effect. Moreover, we introduced the free serratus anterior muscle-fascial composite tissue flap as a safe and novelty surgical procedure for moderate-severe PHA. MethodsThis clinical study included four patients who received a free serratus anterior muscle-fascial composite tissue flap and 19 patients who received Coleman fat transplantation. Preoperative (preoperative photograph and imageological examination) and postoperative (postoperative photograph, complications, therapeutic effect, and satisfaction) assessments were performed for all PHA patients. Body Image Concern Inventory (BICI), Self-rating Anxiety Scale (SAS), Self-rating Depression Scale (SDS) were performed preoperatively and postoperatively. ResultsAll the cases were cured with a good appearance with two kinds of operations. Free serratus anterior muscle-fascial composite tissue flap could correct face defects in one surgery and achieve good long time and short-time postoperative satisfaction in moderate-severe PHA. Fat transplantation could also enhance appearance in numerous operations for mild-moderate PHA. The volume of free-fat grafts decreased obviously after implantation in many cases. So, many patients (42.11%) accepted a series of operations to achieve satisfied postoperative effect. BICI, SAS, SDS score decreased a year later in all patients. ConclusionFree serratus anterior muscle-fascial composite tissue flap transplantation is an effective and safe treatment for moderate to severe PHA.
