[Acoustic impedance measurement in the diagnosis of hypoacusis in children].

In 1986-1988, we examined 1105 children no older than 15 years with various forms of hypoacusis. It was found that measurement of acoustic impedance can help topical diagnosis at any age, especially in children younger than 3 years. In 1988, we examined 350 children with conductive hypoacusis. The specific features of tympanography and acoustic reflexes allow early and accurate diagnosis of middle ear abnormalities. It is stressed that measurement of acoustic impedance may play an important role in examinations of patients with middle ear pathologies.
