Clinical observations were made of 42 children with bilateral idiopathic progressive sensorineural hearing loss considering hearing loss distribution in relation to age at onset, audiometric features, audiologic characteristics and possible correlation with some haematochemical alterations. Patients were divided into 2 groups on the basis of hearing onset: Group I, 0–6 years; Group II, 7–14 years. A peak in the distribution of onset age was observed in the range of 4–6 years. In most cases a ‘descending’ curve was recognized accompanied by recruitment. The haematochemical tests only suggested a possible correlation between hearing loss and anaemia. Finally, no significant difference of incidence between the sexes was observed.
