Reconstrucción con doble colgajo libre del piso anterior de la boca: informe de tres casos / Reconstruction of the floor of the mouth with double free flap: report of three cases

ABSTRACT

BACKGROUND: We undertook this study to describe three cases of reconstruction of the floor of the mouth with two simultaneous free flaps. METHODS: Three patients with cancer of the anterior floor of the mouth were subjected to segmental resection of the mandible and resection of the floor of the mouth with subsequent reconstruction using two simultaneous osseous and fasciocutaneous free flaps. RESULTS: All patients had a satisfactory evolution. Two patients underwent adjuvant radiotherapy, one due to the initial clinical stage and the other due to positive surgical margins. The third patient had neoadjuvant postoperative radiotherapy and concomitant chemoradiotherapy. CONCLUSIONS: If a tumor involves osseous structures of the anterior floor of the mouth, it is best to perform surgery with wide margins with segmental resection of the mandible. Surgical technique is the decision of the surgeon how many and which types of flaps will be used for reconstruction of the anterior floor of mouth. When there is necrosis of a free flap in the head and neck region, attempt with another free flap is recommended.
