Modified Reconstruction of Brown II Defects With Anterolateral Thigh Flaps Following Tumor Resection.

Abstract

Maxillary defects reconstructed with flaps usually cause nasalomaxillary fistula, discomfort oral lining, and poor function of denture. To resolve these problems, this study introduces a modified method of anterolateral thigh flap (ALTF) with skin and myofascial paddles to reconstruct nasal and oral lining of maxillary defects. This study retrospectively reviewed 66 consecutive patients of Brown II maxillary defects following tumor resection reconstructed with ALTFs of modified or conventional methods. In modified group, oral lining was reconstructed with myofascial paddle and nasal lining was reconstructed with skin paddle. The functional and aesthetic outcomes, and the scores based on the University of Washington quality of life questionnaire were assessed. All flaps were successful in reconstruction of Brown II maxillary defects. No nasalomaxillary fistula and obstruction of the nasal cavity were found in modified ALTFs group. The functions of removable denture were better in modified ALTFs group. There was no significant difference about tumor recurrence, range of mouth opening, and aesthetic outcomes between the 2 groups. The modified method of ALTF with skin and myofascial piddle to reconstruct Brown IIa and IIb defects following tumor resection is simple and reliable, which improves the oral comfortability and function of denture, and avoids obstruction of the nasal cavity.
