Objective: To determine the appropriate method to use to repair defects after ablation of squamous cell carcinoma (SCC) of the floor of the mouth (FOM).
Methods: A retrospective review of 119 patients who underwent surgical resections of SCC of the FOM and flap reconstructions was conducted. A Student t test was used to examine the statistical differences in operative time, length of hospital stay and complications among groups with different reconstructions.
Results: Advanced-stage patients were repaired with more free flaps than local pedicled flaps that provided more reconstructions for small-to-medium defects. The most common recipient complication was wound dehiscence, and patients in the anterolateral thigh flap group developed a greater number of overall recipient site complications compared with those in other groups. Patients undergoing local flap reconstructions had shorter operative times compared with those with free flap reconstructions.
Conclusion: In contrast to a radial forearm free flap as a more appropriate reconstruction for defects involving the tongue, an anterolateral thigh flap was better suited for defects with dead spaces. A fibular flap was appropriate for massive complex defects involving the mandible, FOM and tongue. A pectoralis major musculocutaneous flap provided the last line of reconstruction for patients with relapsed SCC or high-risk factors for microsurgical reconstructions.
