Objective To analyze middle ear dysfunction and hearing loss among children with cleft palate and to offer evidences for clinical treatment. MethodsThirty-two children with cleft palate and 20 normal children accepted acoustic impedance and auditory evoked potential examination simultaneously and then statistically analyzed the test results.ResultsAs compared with the control group,cleft palate children had significantly difference in the threshold of acoustic impedance audiometry(P0.05) and auditory brainhem response(P0.01).There was no significant difference in dysfunction of middle ear and hearing loss between complete and incomplete cleft palate.In children with cleft palate aged 0～6 years,middle ear dysfunction of different age groups showed no significant differentce.The difference of hearing loss level between 6～18 months and 19 months～6 years was statistically significant(P0.05).Conclusions Most cleft palate children had middle ear dysfunction with secretory otitis media,and led to hearing loss,however,it had nothing to do with kinds of cleft palate.The younger the age,the worse the hearing loss.Cleft palate children necessitate early surgery intervention to cure the co-morbid secretory otitis media.
