Deafness is the most frequent form of sensorial deficit. In the vast majority of cases, the deafness is termed nonsyndromic or isolated and the hearing loss is the only clinical anomaly reported. The majority of cases presenting at birth concern perceptive deafness (with a neurosensory origin associated with the inner ear) rather than conductive deafness (anomalies in the amplification of sound waves between the middle ear and the outer ear).
