ABSTRACT

Objective@#To investigate the treatment and clinical effect of thin anterolateral thigh perforator flap with sensory nerve in the repair of soft tissue defect of dorsal foot.@*Methods@#During January 2012 to February 2017, 14 cases of soft tissue defect of dorsalis pedis were treated. The flap was designed according to the three-dimensional structure of the defect in the recipient area, and the lateral femoral cutaneous nerve was carried. Free transplantation was performed for repair of soft tissue defect of dorsal foot after fine thinning under microscope. The selected size of the flap ranged from 6 cm×4 cm to 15 cm×9 cm, 10 cases of donor site width is less than or equal to 8 cm with direct suture, 4 cases of donor site wound greater than 8 cm, Free skin graft on the wound surface.@*Results@#After operation, all flaps survived. Meanwhile, superficial necrosis occurred in the distal part of the flap in 1 case due to local infection, and healed after dressing change. All patients were followed up for 6-24 months, the appearance of the flap was pleasant, the texture, color and elasticity of the flap were satisfactory. In addition, Partial skin flap two-point discrimination was 6-10 mm with S2, S3 sensory recovery. During the follow-up, patients were able to walk with normal shoes, no ulcer occurred in the flap, and healed well in donor site.@*Conclusions@#The application of thin anterolateral thigh perforator flap with sensory nerve is safe and reliable in the repair of soft tissue defect of dorsal foot. After the repair, the skin flap has a good appearance and can restore part of the sensation.
