Because the anterior wall of the oropharynx plays a very important role in speech intelligibility and swallowing function, the treatment of patients with tongue base cancer remains controversial. The purpose of this study was to investigate surgical approaches for tongue base cancer and postoperative swallowing function. In the period from 1993 until 2006, 23 patients who had undergone resection of the base of the tongue and subsequent reconstruction in our hospital were reviewed. The patients consisted of 18 males and 5 females, and the mean age was 56.7 years old. Four patients were in T1, 3 were in T2, 6 were in T3 and 10 were in T4. In all of the T1 and T2 patients and 3 of the T3 patients it was possible to preserve the larynx, but for the other T3 and all of the T4 patients laryngectomy was performed. In 3 of the T1 cases the larynx was removed by a suprahyoidal approach, and primary closures were performed. These patients had satisfactory postoperative swallowing function. It was a very useful approach for early tongue base cancer. More advanced cases were resected by a mandible swing approach or pull-through method and free flap reconstruction was necessary for these cases. Functional results of those cases were similar to those of patients who underwent microsurgical reconstruction after radical surgery for advanced tongue cancer. It is thought that laryngeal preservation was decided by the surgical defect of epiglottis. When total epiglottectomy was performed, laryngeal preservation was very difficult.
