Abstract

In cleft palate patient, characteristic of speech disorder is the resonance disorder result from velopharyngeal incompetence. Clinically VPI caused by congenital factor as congenital palatal incompetence, submucosal cleft palate, and caused by acquired factor as CNS damage, tumor, palatal palsy. The clinicians more concerned about the speech disorders after cleft palate surgery rather than language pathologist. The resonance disorder devided for hypernasality, hyponasality and nasal emission, but as a rule, hypernasality is typical phenomenon of the resonance disorder. Traditionally clinicians and language pathologists evaluated four-stage or five-stage of hypernasality by subjective assessment. Although language pathologist is well-trained, results of the language level should be different. In late 1980s, Kay Elemetrics Corp. developed nasometer that objective nasalance identified with well-trained language pathologist and originate from nasometer Tonar I and II were developed by Fletcher. Therefore objective nasalance test was possible, the nasometer used in hospital, collage and speech clinic both and home and abroad. Standardization of the cleft palate speech assessment must be settled without delay because of different character result in different language and different assessment results by dialect in same language. In our study, we provide the data base for the standardization of cleft palate speech assessment which through report of objective assessment method, speech therapy effects and problems result in interdisciplinary teamwork by nasometer use in treatment of cleft palate patient.
