Objective: This study aimed to investigate the efficacy and success rate of the anterolateral thigh flap (ALT) in reconstructing total maxillectomy defects.
Methods: This retrospective study involved patients with total maxillectomy defects, who underwent free ALT reconstruction from June 2005 to October 2014.
Results: The study included 72 patients (43 males and 29 females; age range, 7-77 years; mean age, 43 years). Four patients experienced major complications related to surgery: total flap loss in one patient, partial flap necrosis requiring reoperation in one patient, hematoma requiring operative evacuation in 1 patient, and diplopia requiring reoperation in 1 patient. Two patients experienced minor complications: partial flap loss healed by secondary intention with local wound care, and donor site suture rupture in 1 patient healed by secondary intention. Six patients died because of cancer-related death (after local recurrence or metastatic disease). The defects in 5 patients involved the facial skin for which the ALT was segmented into three parts to reconstruct the facial skin, nasal lining, and oral lining. The defects in 4 patients involved the orbital floor for which a segment of tensor fascia lata was included with the flap on the same pedicle and used to repair the orbital floor. In the remaining patients, the free ALT flap, including a segment of vastus lateralis, was used to repair the maxillary defect and fill the dead space. All but one of the surviving patients were satisfied with their final appearance postoperatively.
Conclusion: The free ALT flap with or without fascia lata to repair the orbital floor is safe, reliable, and acceptable for reconstructing total maxillectomy defects.
