舌部分切除後の舌前方欠損に対してsliding tongue flapを用いて再建した1例

抄録

Surgery is the standard treatment for early tongue cancer. After a partial glossectomy, primary closure, skin grafting, or covering with artificial materials is performed. However, these methods may result in distortion, shortening, or narrowing of the tongue and functional impairment. We report a case involving reconstruction using the sliding tongue flap for an anterior tongue defect after a partial glossectomy. A 48-year-old woman with a tongue mass was referred to our department. A 23 × 22 mm tumor was present in the left anterior tongue. A biopsy was performed, and the radiological/pathological diagnosis was squamous cell carcinoma (T2N0M0). The patient underwent a partial glossectomy and sentinel lymph node biopsy under general anesthesia. After the partial glossectomy, reconstruction using the sliding tongue flap was performed. Since histopathological findings showed left cervical lymph node metastasis, a neck dissection was performed. Although the patient’s tongue was shortened slightly after the operation, its movement was generally good. There was no recurrence nor metastasis seven years and seven months after the surgery.
