Fluoroscopy and nasoendoscopy in designing palatal lift prostheses.
Prosthodontists frequently provide prostheses for the management of speech disorders related to palatopharyngeal dysfunction. Optimal prosthetic management of the palatopharyngeal port requires close interaction between the prosthodontist and speech pathologist in the use of videofluoroscopy and videonasoendoscopy for design, placement, and modification of the prosthesis. Function of the palatopharyngeal port during production of controlled samples of connected speech can be observed from multiview fluoroscopy, including lateral and frontal projections. Like fluoroscopy, nasoendoscopy can be used to observe and record function of the palatopharyngeal port during speech. This article provides an overview of the procedures suggested for diagnosing palatopharyngeal disorders. A method for designing and placing a prosthesis to aid in obturating the nasopharynx is also suggested.
