Abstract
Background
Progressive hemifacial atrophy often causes lip vermilion defects in patients. In this study, we described a one-stage repair method for lip defects in progressive hemifacial atrophy using a lip vermilion mucosal flap or combined dermal fat flap graft.
Patients and Methods
Patients diagnosed with progressive hemifacial atrophy with lip vermilion defects from 2010 to 2022 were included in this study. Based on the severity and location of the patient's lip defect, a lip vermilion mucosal flap was designed and transferred to the lip defect or combined with a hip dermal fat flap for one-stage repair of the lip morphology. Lip morphology and function of patients were followed up after surgery.
Results
A total of 22 patients were enrolled in this study, including 15 patients with lip defects on the upper lip alone and 7 patients with both upper and lower lip defects. Follow-up six months to two years postoperatively, all patients recovered uneventfully without complications. The repaired lips of the patient had a full and symmetrical morphology with no visible scarring. Two patients experienced transient dysesthesia of the lips postoperatively and both returned to normal after three months. All patients had good lip closure with normal dietary and speech function.
Conclusions
The method we described for repairing lip defects in progressive hemifacial atrophy can achieve satisfactory aesthetic and functional lip results. The distinct advantage of this approach is that the patients undergo only one-stage operation and it can be used to repair both upper and lower lip defects.
