Radial forearm free flap for reconstruction of the oral cavity: clinical experience in 55 cases.

Objective: Since the advent of modern microvascular techniques, the radial forearm free flap (RFFF) has become a reliable method for reconstruction of defects within the oral cavity. The purpose of the present study was to evaluate our experience with the use of the RFFF for the reconstruction of oral cavity defects after tumor resection.

Study Design: During a 9-year period, 103 consecutive patients were treated in our department for the reconstruction of oral defects after tumoral ablation by means of microvascularized free flaps. Fifty-five patients were reconstructed by means of the RFFF. Patients were treated for benign (n = 1) and malignant (n = 54) entities. All the patients underwent an abdominal split-thickness skin graft for the closure of the donor site.

Results: Fifty-five patients underwent reconstruction by means of the RFFF after resection of the oral cavity. Squamous cell carcinoma was present in 54 patients. A mean age of 55.5 years was observed (range 16-78). Thirty-nine patients (70.9%) were men and 16 (29.1%) women. Primary reconstruction was achieved in 52 patients (96.3%). A fasciocutaneous graft was used in all of the cases, with a mean size of 7.39 x 5.17 cm. The mean flap ischemic time was 56.02 minutes. During the immediate follow-up period, revision of the vascular anastomosis was necessary in 18.9% of the cases owing to flap ischemia.

Conclusion: Our results revealed that the RFFF is a reliable method for reconstructing a wide range of oral cavity defects with an acceptable low morbidity rate. It provides adequate bulkiness and pliability, resulting in adequate reconstruction of a wide variety of defects within the oral cavity.
