Observation on Hearingloss and Language Development in Atresia Auris Congenita

Abstract

We examined the hearingloss of 31 cases in 4-7 years old children who had congenital malformation of the external ear.
In case of congenital malformation of bilateral. external ears, two cases were diagnosed as sensorineural hypoacusis and the others conductive hypoacusis. The hearingloss of the bilateral microtia was found to be more severe than that of the unilateral microtia combined no other deformity.
Characteristically, 6 out of 31 cases were seemed to be concerned with salidmide.
Regarding to language development, children showed congenital conductive hypoacusis were favourable in development of vocabulary, articulation, language comprehension, discrimination score and special training, in comparison with children showed sensorineural hypoacusis with the same grade of hearingloss as above conductive hypoacusis.
