Suturethese two flaps in the middle line. Close the skin wound with mattress suturesso that there is eversion and the thin skin is so approximated that leakage andnecrosis is not likely to occur. Some surgeons have recommended that the osseous defect be closed bymeans of a flap of bone obtained from the crest of the ilium and provided witha pedicle.
