Characteristics of the Hearing Loss in Unilateral Cleft Lip and Palate-Influence on Communication

Etiology of otitis media with effusion (OME) is still unclear and often described as multi-factorial. It is very usual finding in cleft palate population. We tested relationship between the hearing level, audiometric frequencies, aging and ear side in unilateral cleft lip and palate 101 children (UCLP) and subgroups of left (UCLP)(L) and right cleft side (UCLP)(R). Group of left ears is prone to higher frequency and more severe hearing disturbances than groups of right ears, with less chance of normalizing hearing level with aging. Characteristics of hearing loss level and its improvement, in UCLP children depend of cleft type, ear side and age group
