To investigate the potential impact of a history of cleft lip and/or palate (CL/P) on medial olivocochlear (MOC) efferent system modulation in children.DesignCross-sectional study.SettingUniversity-affiliated audiology research laboratory under controlled acoustic conditions.ParticipantsFifty-two children aged 9 to 15 years with typical hearing participated, including 26 children with surgically repaired,...
Children with a history of cleft lip and/or palate show measurable differences in medial olivocochlear efferent function; audiologists managing this population should consider including TEOAE contralateral suppression testing as part of comprehensive audiological assessment.
Understanding efferent auditory system differences in cleft lip and palate populations may explain listening difficulties beyond standard audiogram results and help tailor audiological management in this at-risk group.
