Audiological findings in cleft palate patients attending speech camp

Hearing impairment is one of the associated problems seen particularly in children with cleft palate rather than cleft lip alone. This has received very little attention in the area of cleft care although research shows that hearing impairment affects language development The present study was carried not to find out the type and pattern of audiogram in cases attending a speech camp, average degree of hearing loss and its relation to the side of cleft, and the acoustic immittance findings and its relation to the otological evaluation. The parental awareness about the hearing problem was also assessed.

The study was conducted on cleft palate patients attending a speech camp. In all, there were 43 patients (19 males and 24 females) in the age range of 3-22 yr. All had undergone audiological assessment, speech and language evaluation, and otological evaluation using standard procedures.

Hearing loss was seen in 38 (88.38%) patients. It was the first audiological assessments they ever had. The average pure tone Thresholds revealed a reverse-ski pattern with a wide air-bone gap. The degree of hearing loss ranged from 25 to 68 dB indicating that untreated otitis media resulted in moderate to moderately severe degree of hearing loss. The immittance findings supported the extent of extracranial complications identified on otoscopic examination. There were more patients with unilateral cleft of the left side with greater hearing loss in the ear alongside the cleft.

Hearing loss is prevalent in more than three-fourths of the patients attending the speech camp. There is a need for early identification and intervention of middle ear effusion for all cleft palate cases.
