Abstract

Submucous cleft palate (SMCP) is a congenital condition related to abnormal muscle attachments within the soft palate. Even though hypernasality and nasal emission, the primary symptom of SMCP, have been well-documented, research on articulation errors is currently lacking. The object of this study was to examine the consonant articulation in patients with unoperated SMCP and its possible correlation with the velopharyngeal function. This study analyzed the perceptual speech assessment and nasopharyngoscopy data of 338 patients with unoperated SMCP between years 2008 and 2016 retrospectively. The mean age of the patients was 13.27 years. About 125 patients showed velopharyngeal competence (VPC), 174 velopharyngeal incompetence (VPI), and 39 marginal VPI (MVPI). Among the 338 patients, 137 presented normal articulation, 124 consonant omission, 25 compensatory articulation, 36 consonant weakening, 51 consonant substitution, and 36 posterior placement. About 70.40% VPC patients, 17.24% VPI patients, and 48.72% MVPI patients demonstrated normal articulation. About 59.20% VPI patients showed consonant omission. The results demonstrated that consonant articulation varied among patients with unoperated SMCP and was correlated with their velopharyngeal functions, while consonant omission was the most common articulation error. Velopharyngeal closure pattern was not associated with either velopharyngeal function or consonant articulation.
