Clinical outcome of reconstruction of the lateral oropharyngeal wall with an anterolateral thigh free flap

Abstract

The anterolateral thigh (ALT) free flap is widely used for various reconstructions in the head and neck. However, its use in the oropharynx has not been widely evaluated, so we have reviewed our experience. We retrospectively reviewed the medical records of 28 patients with oropharyngeal cancer, who were treated with immediate reconstruction with an ALT free flap after excision. We recorded history, stage of tumour, course of operation, postoperative period, oncological treatment, clinical outcome, and follow-up. The mean age of the patients was 61 years (range 44–83). Ten of the patients had clinically relevant coexisting conditions. Most of the patients had T3-4 tumours and involved neck nodes. The operations included resection of the tumour, neck dissection, and reconstruction of the oropharynx with an ALT free flap. All donor sites were closed primarily. Eight patients (29%) developed early local complications that required reoperation. Ten patients (36%) had postoperative cardiopulmonary problems. Twenty-seven flaps succeeded; one was lost. There were no other complications or late problems of the donor site except one seroma. Twenty-one patients were given postoperative radiotherapy. After the mean follow-up period of 40 months (range 13–68) 20 patients (71%) were disease-free. Three patients required a permanent gastrostomy and one a permanent tracheostomy. We conclude that the ALT free flap can be used successfully for reconstruction of a lateral oropharyngeal defect with manageable postoperative morbidity.
