Abstract

The purpose of this study was to investigate whether CPAP therapy was effective for reducing the degree of hypernasality in individuals with repaired cleft palate and whether the efficacy of CPAP therapy was maintained. Five individuals with cleft palate participated in an 8-week home-based CPAP program. Results from perceptual evaluation of hypernasality and nasalance scores before and after CPAP therapy and at the follow-up speech evaluation were compared. The results of the study showed that the responses of the CPAP therapy were various among individuals. Three individuals exhibited reductions in the degree of perceived hypernasality, while nasalance scores in all individuals decreased after the therapy. The results showed that the effect of CPAP therapy was generally maintained until approximately three months after the completion of CPAP therapy.
