Application of free anterolateral thigh tissue flap in repairation of tissue defects in total or near-total glossectomy

Abstract

Objective To evaluate the functional outcomes of the flaps repaired with free anterolateral thigh tissue flap in patients who had total or near-total glossectomy. Methods From March, 2015 to May, 2018, 15 patients with tongue cancer were treated by total or near total tongue resection. The free anterolateral thigh tissue flaps were used to repair the defects of tongues after radical tumor resection. The size of 15 flaps were 6 cm×10 cm to 8 cm×15 cm. Patient data were retrospectively analyzed. Patients were requested to conduct the postoperative reviews. Results All 15 flaps survived, while 1 occurred vascular crisis which was survived after the exploration and corresponding treatment. As the results of 12 to 48 (average 30) months followed-up by clinic visits, the mouth and chewing function recovered well after 6 months, while the swallowing and pronouncing function were poor. The motion of thigh donor area was good, without numbness, pain and discomfort. Conclusion The defect being left after total or near-total tongue resection is repaired and reconstructed with anterior lateral cutaneous tissue flap, which is able to partially restore the functions and shape of the tongue.
