Gaines,1 in her study of the problem, postulated that cleft-palate children were prone to middle-ear pathologies because of the exposure of the Eustachian tube to pathological insult or because of irregularities in the tubes. She concluded that there is a greater incidence of hearing loss in cleft-palate children and that the basis for the hearing loss was dysfunction of the Eustachian tube because of anatomical deviations of the related musculature.
