Abstract:
Objective:To investigate the feasibility of one-stage thinning of latissimus dorsi muscle, rectus abdominis muscle and gracilis flap in reconstruction of the hand and foot defects.
Methods:From June 2009 to April 2015, 24 free muscle flaps were thinned during transfer operation by removing their superficial muscle layers on the basis of their vessel pedicles running in the deep surface of flaps. The surface of the muscle flaps were covered by split-thickness skin grafts. There were 16 latissimus dorsi muscle flaps, 4 gracilis flaps and 4 rectus abdominis muscle flaps. Flap size ranged from 6 cm×4 cm to 20 cm×12 cm. Thinned muscle flaps were used to resurface 7 hand defects and 17 foot defects.
Results:All muscle flaps survived the thinning procedures without any circulation problems except for one case which suffered total flap necrosis due to venous thrombosis. Skins grafts on muscle flaps also took well. One patient experienced partial skin loss. Two patients underwent secondary debridement and thinning procedure for infection and bulkiness. During the 0.3-20 months follow-up, the contour of thinned muscle flaps matched well with the recipient areas. Reconstructed feet are able to wear regular shoes.
Conclusions:Intraoperative immediate thinning of free muscle flaps can be safely accomplished during the primary reconstruction procedure. This procedure prevents the limitations of muscle flap bulkiness and may provide an alternative for surface coverage.
