Abstract

ImportanceReconstruction of the facial nerve after radical parotidectomy is commonly performed with cable grafting, which is associated with slow recovery of nerve function and synkinesis.ObjectiveTo describe facial nerve reconstruction after radical parotidectomy using concurrent masseteric nerve transfer and cable grafting.Design, Setting, and ParticipantsThis retrospective medical record review at a tertiary referral hospital included 9 patients who underwent concurrent masseteric nerve transfer and cable grafting for facial nerve reconstruction performed by a single surgeon from January 1, 2014, to October 31, 2015. Final follow-up was completed on March 14, 2016.Main Outcomes and MeasuresImprovement in resting facial symmetry and oral commissure excursion and synkinesis.ResultsNine patients (6 women; mean age, 62.6 years; age range, 51-73 years) underwent immediate facial nerve reconstruction after radical parotidectomy using concurrent cable grafting and masseteric nerve transposition. All patients had return of oral commissure motion within 2 to 7 months after surgery with good excursion and minimal synkinesis.Conclusions and RelevanceMasseteric nerve transposition can be combined with cable grafting to improve outcomes in facial rehabilitation after radical parotidectomy.Level of Evidence4.
