Abstract:
An intraoral prosthesis with a soft flexible obturator was provided for a patient with a soft palate perforation after surgical and chemoradiotherapy treatments of a soft palate tumor. An obturator composed of movable and flexible silicone was attached to a structure similar to a palatal lift; it was therefore able to move according to the movement of the soft palate, which was confirmed by endoscopic examination. The application of this prosthesis resulted in complete disappearance of hypernasality and food reflux, and the patient was able to eat without particular limitation during daytime wearing. This type of prosthesis represents a potential prosthetic approach to a soft palate nasal-oral fistula.
