Research Abstract

Hypernasality and the velopharyngeal insufficiency after the maxillary resection become the major stress for the patients. Obturator prosthesis is used to restore a normal language. So we associate the function precisely, and treat the disorders appropriately. Generally, a perceptual assessment is important to an evaluation of the nasopharyngeal function, however unevenness is found in an evaluation by a difference of the clinical experience. Therefore it is necessary to raise the reliability of the evaluation by putting the testing using the instrument including nasalance scores (NS) and the fiberscope finding. These instruments are expensive, and the purchase is difficult, and there is the fault that we cannot use in all institutions, and we are noninvasive, and reliable technique is demanded, but there is not the report of these technique so far. We assumed these data and technique a base and thought whether we could not establish a new assessment method. A viewpoint is to link a characteristic frequency region to NS, and it is to be able to assess the hypernasality which we determined at a glance. The subject is ten patients who wear obturator prostheses after maxillary resection. We conducted NS measurement after wearing if before obturator prostheses wearing and recorded an utterance sound to a digital recorder and measured a characteristic frequency region by a sound analysis software Multi-Speech. NS were reduced after wearing the prostheses. The characteristic frequency region level compared F1, F2 before wearing prpstheses together, and a value decreased after wearing.
