Abstract: Objective: To investigate the method of modified pudendal thigh flaps transfer for vaginoplasty.Methods: The modified pudendal thigh flaps were formed which the subcutaneous fat of half distal end was clipped and subdermal vascular network was conserved.Results: All five cases of flaps were survived with primary healing.The flaps had no overcrowding and scar.The reconstruction vaginoplasty was spacious which the width was two fingers and the depth was about 10-12 cm after 6 months to 1 year.Conclusions: The modified pudendal thigh flaps used in vaginal reconstruction are thin and have rich blood supply,the contour of the vulva is satisfied.The lacuna is enlarged and not shift outward easily.
