Aided auditory thresholds in children with postmeningitic deafness.
Postmeningitic hearing loss is often bilateral, profound, and rapid in onset. Children with postmeningitic hearing loss may be identified as potential candidates for cochlear implantation. The length of time required for a definitive trial with conventional amplification, which must precede a final decision regarding cochlear implant surgery, has been the subject of debate. Twenty-five children with bilateral severe-to-profound postmeningitic sensorineural hearing loss were fitted with appropriate amplification and results of serial-aided tests were analyzed to determine the degree of benefit and changes in aided thresholds over time. Twelve children gave aided responses that clearly indicated the presence of residual hearing and good aided benefit. Ten youngsters have responded consistently in the vibrotactile range when aided, thus receiving limited benefit from conventional amplification. Of particular interest are three children who initially exhibited limited or no auditory responses but who, after a period of 16 to 25 months, showed excellent benefit with binaural hearing aids. These children are all in total communication programs and have received good auditory training. Caution should be exercised when concluding that such a child does not benefit from amplification.
