Use of the Lateral Circumflex Femoral Artery Perforator Flap in the Reconstruction of Gunshot Wounds to the Face

Abstract

The reconstruction of large avulsive tissue loss in the head and neck region is one of the most difficult tasks faced by reconstructive surgeons. The advent of free tissue transfer has improved our ability to predictably reconstruct these patients. One of the most recent advances in the field of microvascular surgery is the use of perforator flaps. We have used the lateral circumflex femoral artery perforator (LCFAP) flap for reconstructions in patients who have suffered severe gunshot wounds (GSWs) to the maxillofacial area. A retrospective chart review was conducted of patients treated with a LCFAP flap in our division for large defects of the face resulting from GSWs between July 2005 and July 2006. The patient's age and gender, site and size of defect, and degree of bone and soft tissue loss were recorded. Flap survival and donor site morbidity were noted as outcomes of the reconstruction. Four patients who met the inclusion criteria were identified. The success rate for the flaps was 100%. There was no partial necrosis of the flaps. The size of the defect ranged from 20 x 10 cm to 10 x 10 cm. None of the patients had donor site complications, and all donor sites were closed primarily. Use of the LCFAP flap for the reconstruction of large defects secondary to GSWs to the face is a reliable option for the immediate reconstruction of this patient population. The lateral circumflex femoral artery perforator (LCFAP) flap is at a site not involved in the immediate resuscitation of trauma patients, thus ensuring an intact vascular system. This fact makes the LCFAP flap a reliable source for small to large soft tissues for reconstructing avulsive soft tissue losses in the head and neck.
