Finally, the abscess was filled with a free greater omentum flap, accompanied by microvascular anastomosis.

For the whole defect of scalp with skull exposure the authors consider the free anterior-lateral femoral flap more appropriate and suggest that the free omentum flap be avoided as far as possible.

Experience on 108 cases of clinical application of microsurgery is reported in flaps transfer, myocutanous flap transfer, fascia grafting, great omentum grafting and microlymphangiovenous anastomosis.
