An aetiological survey of 3, 064 deaf children

We have completed a survey of the causes of deafness in 3, 064 children with defective hearing who attend special schools in Southern Africa. Specific genetic or multifactorial syndromes were diagnosed in 7 per cent, familial undifferentiated deafness was recognized in 11 per cent, while in 25 per cent the deafness was acquired. © 1983, JLO (1984) Limited.
