Clinical application of thoraco-umbilical skin flap

Since 1987 we have successfully used thoraco-umbilical skin flaps as free transplants to repair 8 cases of severe burn scar deformities of jaw-neck and hand regions, thoraco-umbilical insular skin flaps to each case of congenital vaginal atresia, severe vulval scar due to sulfuric acid burn and large penal tissue defect accompanied with severe urethral leakage. This flap has the following advantages: namely definite anatomical position, larger vascular diameter, fight large skin flap area, and similar skin completion as that of the jaw-neck region. Therefore they are the ideal substitute for the repair of soft tissue defects of jaw-neck region as well as extremities. The flap has long vascular pedicle, abundant vascularization, easy transportation and it is suitable to be a retrograde insular flap for repairing of vulval tissue defect, reformed penal vaginoplasty.
