Experience of 73 free groin flaps.

The free groin flap has gradually lost its popularity due to the disadvantages relating to the pedicle and the plethora of new donor sites. The purpose of this article is to re-evaluate this time-honoured free flap and to demonstrate its reliability and versatility through a review of 73 free groin flaps performed between 1985 and 1990. 7% of free transfers (total 1096 cases) in our institution were free groin flaps. The complication rate was 8% (three complete failures and three partial failures). This result is acceptable and not so high as other reports have described. The artery discrepancy is the main cause of the complication rate. Two special techniques to gain additional diameter of vessel size to overcome the pedicle disadvantages are stressed. The groin flap has proved to be useful and still deserves consideration in reconstructive procedures.
