A study on the hearing of children with non-syndromic cleft palate/lip.
Children with cleft lip/palate often present otitis media as a result of anatomic and/or functional alterations of the Eustachian tube.


OBJECTIVE
To analyze the results of Basic Audiologic Evaluation (BAE) and Auditory Processing Screening (APS) in children with cleft lip/palate.


METHODS
Prospective cross-sectional cohort.


METHODS
Forty-four male and female children, within the 8 to 14 age range with non-syndromic cleft lip/palate, referred by the institution where the study was carried out. The BAE was made up by an interview, otoscopy, threshold tonal audiometry, logoaudiometry and impedance test. The APS was made up of 3 basic tests: Sound Localization Test, Sequential Memory for verbal and non-verbal sounds and Dichotic Listening Test.


RESULTS
The BAE revealed that 77.27% of the children presented normal hearing; 13.6% had conductive hearing loss and 2.2% presented mixed hearing loss. 21.2% of the children had type C tympanometry curve; 7.1% had a type B curve and 3.5% had an Ad curve. The APS was altered in 72.7% of the children and 45.5% of them presented altered results on the Dichotic Listening Test.


CONCLUSIONS
Children with cleft lip/palate had altered results on BAE and APS, which justifies audiological and medical follow-up.
