Abstract
To improve the swallowing function of glossectomized patients with dysphagia after glossectomy, we newly fabricated a bolus-transportable palatal augmentation prosthesis (Trans-PAP), which is mounted with a bolus-transporting device to a conventional palatal augmentation prosthesis (PAP). In this paper, the structure of Trans-PAP is described and its clinical effectiveness for dysphagia in a patient undergoing subtotal glossectomy is reported.The patient was a 57-year-old man who underwent surgical reconstruction using a rectus abdominis myocutaneous flap immediately after subtotal glossectomy. Postoperative dysphagia was mainly caused by dysfunction of the pumping movement of the tongue. A Trans-PAP was applied. The bolus-transportation plate of Trans-PAP can press on the reconstructed tongue by spring action. Consequently, it is possible to compensate for tongue pressure and the pumping movement of the tongue. The results of functional examinations showed that swallowing function was restored by Trans-PAP.
