title: Medical profile of the language-delayed child: otitis-prone versus otitis-free.
abstract: Delay in language development may be associated with an underlying anatomical, neurosensory, or psychological disorder such as: deafness, cerebral palsy, cleft palate, autism, or mental retardation. A condition called specific developmental language delay may occur in children devoid of any other identifiable disorder or developmental delay. Language delay associated with early onset, severe-to-profound hearing impairment has been well documented. Controversial studies have also appeared in the communicative disorders' literature suggesting that fluctuating conductive hearing loss in early childhood can significantly affect the development of language and related academic skills. Some authors have claimed that these deleterious effects can be irreversible. This study focuses on 3 groups of preschool children, in whom hearing acuity has been documented: One group with recurrent otitis and language delay; a second group with an equally well documented otitis history but without language delay; and a third group with documented language delay in the absence of any known predisposing conditions, including early-onset, recurrent otitis media. Prenatal, birth and developmental histories of the children in each group were compared in detail to identify any factors which may enhance or ameliorate the effects of fluctuating conductive hearing loss on language development. In a population of 1864 children (ages 9-59 months) referred for otolaryngologic and/or communicative evaluation, 480 otherwise normal children (67.6% males; 32.4% females) were found to have a history of early-onset, recurrent otitis media and/or delayed speech and language development on the basis of an extensive evaluation battery. This population was further subdivided into 3 groups (I = otitis-positive/normal language; II = otitis-positive/language delay; and III = otitis-free/language delay). Among the 329 children with positive histories for early otitis media (Groups I & II), a significantly higher percentage of those demonstrating language delay were from homes in the lower socio-economic category. Race and sex showed no significant relationship to language delay among the otitis-positive groups, although males were twice as numerous as females in the over-all study population. Articulation errors on speech measures and borderline delays in other developmental milestones (standing, walking, and toilet training) were also significantly greater in the language-delayed group when compared with otitis-positive children whose language was age-appropriate.(ABSTRACT TRUNCATED AT 400 WORDS)
