Defective speech due to velopharyngeal insufficiency occurs from various causes such as cleft palate. In determining treatment for such defects and evaluating the outcome, diagnosis of velopharyngeal insufficiency is important. Though various diagnostic methods have been reported, none seems to be objective and accurate. We have performed audiometry and hydrodynamic examination as well as electroacoustic examination. Recently, nasopharyngeal fiberscope added for comprehensive evaluation. In this study, comparison was made between the findings obtained by hydrodynamic examination and those with a nasopharyngeal fiberscope in patients with velopharyngeal insufficiency following cleft palate repair and controls, and the following results were obtained. 1. A correlation was suggested between the amount of velopharyngeal insufficiency (open area) and that of intranasal breath exhalation. These factors affected the intraoal pressure and the degree of asaphia. 2. This comprehensive method may be useful in detemining the applicability of speech aid or pharyngeal flap operation as well as evaluating outcome.
