Application of superficial iliac island flap in wound repair after resection of mons pubis hypertrophic scar / 中国医师杂志

ABSTRACT

Objective To explore the repair effect of the superficial iliac island flap for the hypertrophic scar of mons pubis after burned.Methods From July 2013 to July 2016,the author had treated 26 patients with mons pubis hypertrophic scar after burned.There were 19 males and 7 females among them.The age was from 1 year and 5 months to 10 years old.The scar area was of 6 cm ×5 cm-15 cm ×8 cm.Some of the patients had external genital malformations caused by scar contracture.Surgery removed the scar and completely released the basic shape of the vulva.It had to expand the superficial iliac island flap of 1 cm according to the size of the wound,and sufficient length of vascular pedicle according to the distance from the wound to the flap.The flap was cut in the superficial of the deep fascia,and reserved about 2cm wide fat along the superficial iliac artery.The superficial vein was located in the fat.The wound was covered by the flap,which was rotated directly or through a subcutaneous tunnel.Results Twenty six patients were treated with a single operation and no vascular crisis occurred.All the flaps survived.One patient delayed incision healing due to the high incision tension,and the remaining patients were in primary healing.The postoperative follow-up found that all the flaps had thin thickness,similar color to the surrounding skin,soft texture and feeling.Conclusions There are obvious signs of scarring in the mons pubis area after deep burns,and scar contracture can cause vulvar deformity.The superficial iliac island flap,which has a thin thickness,soft texture,similar color,and can be sutured directly for the donor site,is a good choice to repair the mons pubis hypertrophic scar.
