Single perforator based anterolateral thigh flap for reconstruction of large composite defects of oral cavity.

Composite defects of oral cavity are a reconstructive challenge. Anterolateral thigh flap provides large and pliable tissue for reconstruction of these defects. However, wide variations in the vascular anatomy, variable perforator number and location are reported. The aim of this study was to evaluate the reliability of single perforator based large anterolateral thigh for reconstruction of complex oral cavity defects following ablative surgery. We report a series of 25 consecutive patients who underwent reconstruction of oral cavity defects with anterolateral thigh flap based on single perforator between August 2009 and August 2010. The mean flap dimension was 261cm(2) (range 80-540cm(2)). In 21 patients the flap was bi-paddled and used for inner and outer lining for cheek. None of the flaps developed perforator insufficiency. Two flaps were lost due to delayed neck wound sepsis after 7th post operative day. This study establishes safety and reliability of using a large and/or bi-paddled anterolateral thigh flap based on single perforator for reconstruction of complex oral cavity defects.
