To determine whether the use of tissue spears to remove otorrhoea from Aboriginal children's ear canals improves hearing in the affected ear.
Case series study with controls.
The study comprised 61 Aboriginal children from communities in the remote arid zone of South Australia who had otorrhoea obscuring the tympanic membrane in 1 or both ears. Eighty ears were treated with tissue spears, and hearing was assessed before and after treatment.
Forty-two children had unilateral and 19 had bilateral active disease. An additional 13 ears without otorrhoea served as controls. Improvement by 5 dB HL or greater in a four-frequency pure tone average occurred in 41.3 per cent of treated ears. Subsequently, blinded audiologists made qualitative judgements that a functional improvement in hearing had occurred after tissue spear use in 28.4 per cent of ears.
Tissue spears can improve hearing thresholds in a significant proportion of children with otorrhoea. However, the duration of the effect is unknown.
