A modified groin flap for reconstruction of oral cavity defects after tumour resection

21 patients, suffering from carcinoma in the lower part of the oral cavity, were operated on by in-continuity resection of the mandible. The removed bone was replaced by a metal plate. The soft tissue defect was completely repaired by a modified free groin flap, transplanted with microsurgical techniques. 19 patients had a complete flap take, two flaps became necrotic. No metal plate was lost during a follow up period of 1-20 months. The functional results in respect of tongue mobility were in all cases quite favourable. Techniques of flap raising and transplantation are outlined in detail.
