Total tongue reconstruction with free functional gracilis muscle transplantation: a technical note and review of the literature.
The tongue is one of the most difficult structures of the body to reconstruct if more than 85% to 90% of it has been resected. A functional neotongue requires both soft-tissue bulk and restoration of muscle function. The innervated gracilis muscle flap folded on itself was used to reconstruct a total glossectomy defect. The genioglossus muscle, which makes the greatest contribution to swallowing, and the mylohyoid muscle, which elevates the larynx to prevent aspiration, were simulated with the design and placement of the gracilis muscle. The muscle was placed and secured longitudinally from the remnant of the tongue base and pharynx to the mandible, and then folded on itself and attached to the hyoid bone. The obturator nerve to the gracilis was coapted with the hypoglossal nerve. The patient was able to resume oral feeding without aspiration. Electromyographic results demonstrated reinnervation of the flap with active elevation of the mouth base. The patient died 1 year postoperatively because of recurrence of her disease. This type of design and placement of gracilis muscle transplantation is recommended.
