Primary Free Flaps for Coverage and Reconstruction in Acute Facial Trauma.

Background Acute facial trauma in motor vehicle accident defects may be associated with skeletal, neuromuscular, or mucosal losses. Simultaneous repair of the critical structures in these defects mandates the use of flap cover; paucity of local tissues necessitates the use of free skin flaps. Materials and Methods Six free flap reconstructions for acute facial trauma defects over a 10-year period were reviewed. The defect location, associated injuries, flap choice, additional reconstructive procedures, and flap outcomes were analyzed. Results There were four males and two females with ages between 18 and 63 years. Four defects were located in the lateral face and scalp, and two in the lower central face. Defect size ranged between 96 and 346 cm 2 . There were fractures in three, facial nerve injuries in two, and loss of facial muscles in one. Five free flaps were anterolateral thigh flap; simple and composite, one was a radial artery forearm flap. Recipient pedicles were the superficial temporal vessels in two and facial vessels in four cases. There were no re-explorations but one flap necrosed on 7th postoperative day on account of invasive aspergillosis. Discussion Use of free flaps for ballistic wounds is common. In uncommon nonballistic traumatic facial defects, the location, nature of the defect, and type of associated injuries and need for simultaneous reconstructions may dictate the use of free flaps and permit a one stage debridement, flap coverage, and a simultaneous reconstruction of lost functional units. Conclusion Free flap coverage in high velocity acute facial trauma defects offers a better possibility for primary reconstruction of associated facial injuries and helps in achieving better functional outcomes.

Dual Venous Drainage for the Free Latissimus Dorsi Muscle Flap-Using the Serratus Vein Tributary-Making Virtue of a Necessity.

Background Most flap failures in the lower limb are on account of venous congestion. Literature shows a decrease in the incidence of venous failure when two veins are anastomosed. The thoracodorsal pedicle of the latissimus dorsi free flap affords the possibility of a single venous anastomosis. The lack of a second venous outflow could result in venous congestion in the distal limits of the flap, particularly when long flaps are required for large defects or when the recipient veins are smaller in diameter. Methods We describe a consecutive series of 11 cases of latissimus dorsi flaps for leg and foot defects with a mean defect size of 310 cm 2 , where the serratus anterior vein was used as a second venous outflow channel to ensure maximal venous drainage. Results There were no re-explorations for anastomotic causes. Only one case had partial distal muscle necrosis. There was a delayed anastomotic blowout due to infection resulting in amputation in one case. There was no partial distal muscle necrosis in nine of the ten cases. Conclusion Using the serratus vein as a second venous outflow is of use in reducing incidence of venous occlusion and distal muscle necrosis and can be specially indicated for large flaps and venous diameter discrepancy.
