Audiologic and Tympanometric Findings in Children with Cleft Lip and Palate

Abstract

Objective To evaluate the otologic and audiologic status of 50 children with repaired cleft lip, cleft palate, or both in Hacettepe University, Ankara, Turkey. Design Audiometric and tympanometric evaluation of 100 ears in 50 children were performed. Hearing levels ≤ 15 dB and middle ear pressures between −50 to +50 decaPascals were considered to be normal. Results were examined according to cleft type and laterality. The least and most affected frequencies were calculated. A simple evaluation of speech characteristics including nasal resonance, nasal air escape, and errors of articulation was also performed. Results Sixty-three of the 100 ears had normal hearing status, whereas 40 had normal middle ear pressures. No evidence was found to suggest that individual cleft type and laterality of the ear had any effect on hearing loss or middle ear disease. Two-thirds of the patients had normal or acceptable degree of language skills. Conclusion The final hearing status of patients with cleft palate is a result of a combination of surgical correction, developmental factors, and treatment of middle ear disease. Early and aggressive ventilation tube placement is the standard of cleft care in many countries. Our long-term hearing outcome is relatively good in a population not treated with routine insertion of ventilation tubes. The majority of patients also have satisfactory speech. Patients with cleft palate should have close follow-up for middle ear disease, but further research is warranted to determine the aggressive usage of ventilation tubes.
