The purpose of this study was to evaluate speech production ability of congenitally deaf children with cochlear implant. Forty children were participated in the study. The results are following: (1) mean of speech intelligibility score was 3.05 in 5 point scale, (2) mean of percent of correct vowels was 86.19%, and mean of percent of correct consonants was 74.89%, and (3) voice profiles showed their voice were high pitched, hypernasal, and breathy. But 12.5% of the children were evaluated as having normal voice quality. Overall speech production abilities of children with cochlear implant were superior than the deaf children's result reported in literatures.

Velopharyngeal insufficiency (VPI) is a phenomenon that can occur due to anatomical or neurological causes of the soft palate. VPI can make the patient difficult to articulate through hypernasality and nasal emission. There has been needed the customized treatment, as VPI can occur for many causes. We present the case of 21-year-old male who took palate plastic surgery 20 years ago for congenital submucosal cleft palate. As he had poor contraction of both lateral side of velopharynx, he was diagnosed with coronal type VPI. Through sphincter pharyngoplasty, he can obtain improvement of articulation accuracy. We would like to share this challenged case.
