[A review of 545 consecutive free flap transfers for head and neck reconstruction in a new microsurgery unit].

Objective: To analyze the value of free flap transfers in head and neck reconstruction.

Methods: Five hundred and forty-five consecutive free flap transfers performed in 507 patients from May 1999 to September 2002 were reviewed. Data concerning the operation included date of surgery, defect description and site, stage and histology of tumor, flap type, recipient vessel and complications.

Results: The free fibula flap was most commonly used, followed by free radial forearm flap, rectus abdominis flap, jejunum flap, scapular flap, illiac crest flap, latissimus dorsi flap, and anterolateral thigh flap. The overall success rate of flap was 98.2% (535/545). The overall complication rate was 25.2% (128/507). The vessel thrombosis rate was 4.8% (26/545), and the flap salvage rate was 61.5%(16/26).

Conclusion: Free flap transfer in head and neck region is safe and reliable. It is superior to the conventional pedicled flap technique.
