Objective: To analyze the results of the use of pectoralis major myocutaneous (PMM) flap in the reconstruction of tongue.
Methods: From 1984 to 1995, PMM flap was applied in 86 cases with cancer of tongue after radical resection for the immediate reconstruction of the lingual defect.
Results: Notwithstanding the advanced lesions in stages T3 and T4, patients had good survival and functional results. The 1-, 3- and 5-year survival rate was 86.0%, 51.2% and 23.3%, respectively. There was complete flap necrosis in one case and partial necrosis in fifteen cases, but the latter spontaneously regressed. The swallowing and speech rehabilitations following surgical treatment for tongue cancer were acceptable, considering the advanced disease status.
Conclusion: The PMM flap with its abundant tissue and excellent blood supply and anatomic proximity provides a reliable method of primary reconstruction of the substance of the tongue. The surgical procedure is simple, easy to perform. Reconstruction of the tongue with PMM flap meets the clinical requirements in the shape, communication and swallowing rehabilitations. The PMM flap is a reliable material for the reconstruction of tongue with major defect following subtotal glossectomy.
