Facial functional outcomes analysis after reconstruction by vascularized thoracodorsal nerve free flap following radical parotidectomy with facial nerve sacrifice.

Abstract

Parotid spread tumor may occasion wide defect with facial nerve sacrifice. We report our one time reconstruction experience of this defect using a thoracodorsal artery perforator and nerve flap (TAPN). Eight patients underwent a radical parotidectomy with facial nerve sacrifice between February 2010 and June 2016. A single time reconstruction was performed using a thoracodorsal artery perforator and nerve flap, with skin or fat paddle. The thoracodorsal nerve vascularized was harvested and used to reconstruct the facial nerve from the trunk to four until six distal branches. Patients underwent physiotherapy for 3 months at least. Facial outcomes were assessed using House-Brackmann scale and eFACE application. Mean follow-up was 30 months. No complication occurred on donor site. All patients recovered a complete soft eye closure. No Frey syndrome occurred. TAPN is adapted to wide and complex parotid defects.
