Vascularized free fibular flap for the reconstruction of mandibular defects: clinical experience in 42 cases.
OBJECTIVE
Since the advent of modern microvascular techniques, the fibula has become a reliable method for the reconstruction of partial or total mandibular defects. The purpose of this study is to evaluate our experience with the use of the vascularized free fibular flap for the reconstruction of mandibular defects following surgical resection.


METHODS
During a 5-year period, 102 consecutive patients were treated in our department for reconstruction of oral and maxillofacial defects, using microvascularized free flaps. Forty-two patients were reconstructed by means of the free vascularized fibular flap with or without a skin paddle. Patients underwent resection for benign (n = 15) and malignant (n = 27) entities. Fourteen patients received preoperative radiotherapy and only 1 patient received preoperative chemotherapy. The donor site was closed primarily in 7 cases, whereas an abdominal full-thickness skin graft was used in 35 cases.


RESULTS
Thirty-eight patients were treated by means of an osteocutaneous flap, whereas only 4 developed an osseous flap. Five patients developed complications related to the vascular anastomosis and needed a second surgical look. One patient died in the immediate postoperative period. The skin island flap was completely viable in 37 cases (88%). Considering bone survival as the main objective, an overall flap survival rate of 92.85% was achieved in the whole series. Endosseous dental implants were placed in 11 patients with adequate outcome. In 5 of these cases the double-barrel technique was performed.


CONCLUSIONS
Our results reveal that the vascularized free fibular flap is a reliable method for reconstructing mandibular defects with an acceptable low morbidity rate. The use of the osteocutaneous flap provides good reconstruction of composite mandibular defects. It constitutes an adequate support for dental implants.
