Reliability of the superficial venous drainage of the radial forearm free flaps in oral and maxillofacial reconstruction.

Abstract

The aim of this article is to compare the superficial venous drainage system versus dual venous drainage system of radial forearm free flaps (RFFF) and its impact on flap survival. A total of 136 consecutive patients undergoing RFFF reconstruction for oral and maxillofacial surgical defects were reviewed retrospectively. In group l, both the superficial and deep veins were anastomosed to the neck recipient veins. In group 2, only the superficial vein was used for anastomosis. There were no statistical differences in venous problems between two groups (6/68 in group 1 vs. 5/68 in group 2, P = 0.75). The flap survival rate was 98.5% (66/68 in group 1 vs. 68/68 in group 2, P = 0.15). Although there are many theoretical advantages to dual venous drainage system anastomoses, they seem not to impact on flap survival in our experience.
