  1. This table shows the percentages of each type of hearing phenotype for patients with and without palatal defect separately. Palatal defects include cleft palate, submucous cleft and high-arched palate. The group of hearing-impaired patients in which the type was not mentioned, was proportionally divided among the three hearing loss groups. Stickler patients with a palatal defect exhibit significantly more hearing loss, and this can be attributed to the higher number of patients with conductive and mixed hearing loss.
