Extended high-frequency hearing loss in children with cleft palate.
Hearing sensitivity for frequencies 250 through 20 000 Hz was compared between children with repaired cleft palate and a history of otitis media, and children without cleft palate or middle ear disease. All subjects were clear of middle ear effusion during the evaluation. Although children in the cleft palate group had consistently poorer hearing throughout the auditory range, statistical analysis demonstrated significant differences in hearing levels above 9 000 Hz only. No statistical difference was observed for the standard clinical audiometric frequencies. Extra-high-frequency hearing loss appears to be associated with cleft palate and its sequelae.
