The Role of the Anterolateral Thigh Flap for Pharyngoesophageal Reconstruction

Abstract

To elucidate the advantages and disadvantages of the anterolateral thigh flap (ALTF) for pharyngoesophageal reconstruction, we assessed this donor site and compared it with the radial forearm free flap (RFFF). Retrospective medical chart review. Tertiary care referral center. Twenty-three consecutive patients who underwent pharyngoesophageal reconstruction using an ALTF or RFFF. Pharyngoesophageal reconstruction. Patient medical charts were assessed for age, histopathological diagnosis, preoperative treatment, surgical defect, tracheoesophageal speech, flap survival, donor and recipient site complications, and swallowing function. Twenty-three patients (12 who underwent reconstruction with ALTF and 11 with RFFF) were included in the study. Both donor sites provided adequate tissue for pharyngoesophageal reconstruction; however, the RFFF group demonstrated a higher rate of postoperative donor site complications including skin graft loss and extremity edema and stiffness. Postoperatively, the ALTF group demonstrated no gait disturbance and no donor site complications. All 23 patients in both groups were able to tolerate an unrestricted oral diet; however, 3 patients who underwent reconstruction with an RFFF experienced cervical esophageal stenosis, whereas only 1 patient with an ALTF experienced stenosis. In this preliminary series, the ALTF represents an excellent source of tissue for pharyngoesophageal reconstruction and is associated with a lower rate of donor site morbidity and anastomotic stenosis compared with the RFFF donor site.
