Background:
The purpose of this study was to characterize the outcomes of free gracilis muscle transfer for delayed smile reanimation after radical parotidectomy.
Methods:
A retrospective chart review of patients who underwent free gracilis muscle transfer for smile reanimation after radical parotidectomy between 2003 and 2016 was performed. Patient-reported quality of life (Facial Clinimetric Evaluation Scale [FaCE]), physician-reported facial function ("eFACE" facial grading scale), and oral commissure excursion were compared preoperatively and postoperatively.
Results:
Twelve patients were identified with prior surgery and adjuvant therapy (radiotherapy in 6 cases and chemoradiotherapy in 6 cases). Significant postoperative improvements were demonstrated for ipsilateral commissure excursion with smile (preoperatively: -2.2 mm [SD 2.3 mm] vs postoperatively: 7.9 mm [SD 2.5 mm]; P = .002), with meaningful smile achieved in 11 of 12 cases (91.7%). The average duration of facial paralysis before intervention was 72 months (range 12-204 months).
Conclusion:
Free gracilis muscle transfer is an option for dynamic smile reanimation in select patients who have undergone treatment for advanced parotid malignancy.
