title: A functional speech impression used to fabricate a maxillary speech prosthesis for a partial glossectomy patient.
abstract: Surgery for cancer of the floor of the mouth often results in alteration of the muscles of the tongue and floor of the mouth. Both primary and secondary surgical procedures often result in scar formation with reduced mobility of the tongue during speech and deglutition. Speech is often used as a diagnostic tool in the placement of the anterior teeth during fabrication of a prosthesis. Speech can similarly be used to help determine the proper placement of a speech portion of the prosthesis. The prosthetic rehabilitation approach described lowers the palatal vault with a false palate to enable the tongue to function against it during speech (Fig. 15). Group studies have shown that the design and fabrication of speech prostheses for partial glossectomy patients have significantly improved speech and swallowing for these patients. A speech pathologist is helpful during diagnosis, and speech therapy is necessary for significant speech improvement. Prosthetic rehabilitation alone cannot be expected to improve speech.
