Abstract:

OBJECTIVE: To analyze the audiological findings obtained from children with a non-syndromic cleft lip and palate. METHODS: This is a cross-sectional study comprising 128 children of both sexes between 5-10 years of age who underwent audiological evaluation at the Otitis Media Center in the Hospital de Clinicas de Porto Alegre in Brazil. All the children passed the otorhinolaryngology evaluation tests conducted prior to the audiometry, speech audiometry, and acoustic impedance (acoustic reflexes and tympanometry) tests. RESULTS: No statistical differences were observed between the audiologic findings and the sex (p = 0.421) of the children. In addition, there was no difference in the findings obtained from the right and left ears (p = 0.428). We found that 41.7% of the patients showed a changein the hearing threshold, i.e., values >15dBNA in the audiometric research and conductive hearing loss. Of the 41.7%, the hearing loss was unilateral in 83.5%, mild in 75.2%, and moderate in 24.8%. Of the children who showedchanges in hearing threshold, the tympanometric curveswere type B in 63.6%, type C in 29.1%, and type Ad in 7.3% (according to Jerger's classification, 1970 and 1972). CONCLUSION: Based on the results of the audiological assessment of children with non-syndromic cleft lip and palate, hearing loss was observed. Conductive hearing loss was more frequently mild and unilateral. Therefore, we emphasize the importance of otorhinolaryngological and audiological care for these children.
