Incidence of hearing loss among children presented with speech-language delay.

Infants' first attempts to communicate with their environment begin shortly after birth. However, real words appear by age of 12-15 months. Any delay in expressing their needs verbally beyond this age is defined as speech delay and may be associated with a variety of pathological conditions. The aim of this study is to investigate the incidence of hearing impairment in those children presented with speech delay. Ninety-one speech-delayed children were audiologically assessed between March 1993 and March 1995. In 25 out of 91 children (27.4%) a moderate to severe hearing loss was detected, either sensorineural or conductive. The increased incidence of hearing impairment found in this group mandates a thorough hearing evaluation for any case of speech-language delay.
