title: [Application of free anterolateral thigh flap in head and neck surgery].
abstract: OBJECTIVE
  To evaluate the results of reconstruction by free anterolateral thigh flaps (ALT) after operation of head and neck tumors.
  
  
  METHODS
  Forty-three cases underwent the reconstruction of postoperative defects with free anterolateral thigh flaps after head and neck cancer surgeries between November 2007 and June 2010 were reviewed. Ages of the patients ranged from 40 to 81 years, with a median of 56 years; 32 males and 11 females; 23 cases of oral carcinoma, 7 cases of tonsil carcinoma, 11 cases of hypopharyngeal carcinoma, and 2 cases of head skin cancer. TNM classified as follows: no case of distant metastasis; T1 9 cases; T2 17 cases; T3 11 cases; T4 6 cases. All patients were applied with ALT to restore swallowing and respiratory functions. The mean length of blood vessel pedicles of the ALT free flaps was 12.5 (8 - 18) cm. The flaps were 4 - 15 cm in width, 5 - 25 cm in length.
  
  
  RESULTS
  In the 43 cases applied with ALT free flaps, 40 cases were successful and 3 cases unsuccessful. Two of the failed cases were reconstructed with pectoralis major flap. In 11 cases of hypopharyngeal carcinoma, except 3 cases with total laryngectomy, 8 cases (72.7%) had their laryngeal function been preserved.
  
  
  CONCLUSIONS
  The successful rate of ALT free flaps is perfect. There were no serious complication in offered areas. The flap could be shaped into various forms. ALT free flap is an ideal flap to reconstruct the defect after surgery in some head and neck tumors.
