Utility of Digastric Muscle Flap in Reconstruction of Floor of Mouth Defects.

In the era of free flaps, we propose a simple yet effective local flap, the digastric muscle flap, to reconstruct floor of the mouth defects and to repair an orocervical fistula that is created during excision of tongue and/or floor of the mouth malignancies. The digastric muscle flap was used in 15 patients who were diagnosed with oral squamous cell carcinoma of the tongue and/or floor of the mouth. Partial glossectomy was performed in 4 cases, hemiglossectomy in 4 cases, and wide local excision in 7 cases.
