Reconstruction of severe atresic eye socket with lateral arm free flap / 中华显微外科杂志

ABSTRACT

Objective To study the method and effect of lateral arm free flap in reconstruction of severe atresic eye socket.Methods Forteen cases of severe atresic eye socket,from June,2011 to June,2013,were repaired by lateral arm free flap.The flaps were designed and harvested as drop shape with size about 6 cm × 10 cm and then were removed epidermis except distal 6 cm × 6 cm area which were transferred to orbit for eye socket reconstruction.The remaining fascia and dermis were filled to augment temporal defect.Superficial temporal artery was anastomosed with posterior branch of radial collateral artery in 14 cases and superficial temporal vein was anstomosed with radial collateral vein in 11 cases,with middle temporal vein in 3 cases.Results All 14 cases lateral arm free flaps survived with no donor site morbidity.Followed up for 1 year to 3 years,artificial eye could be fitted satisfactorily and temporal contour improved.Conclusion Lateral arm free flap is a recommendable option for severe atresic eye socket reconstruction because of concealed donor site scar,proper volume,matched vascular caliber and minor donor site morbidity.
