ObjectivesTo investigate the overall prevalence of cochlear dead regions in children with moderate to severe sensorineural hearing impairment.MethodsThreshold-equalizing noise (or TEN) test was administered on thirty sensorineural hearing impaired children (8 girls, 22 boys), aged 5–14 years (mean ± SD 8.5 ± 2.8).ResultsClassifying by subject, 76% tested positive for cochlear dead regions in one or both ears at least at one frequency. Classifying by ears, 58.3% had dead regions at one frequency or more. Classifying by the number of frequencies were tested, 20% met the criteria for a dead region. The difference between mean absolute thresholds in two groups was statistically significant at 1000 Hz and below (p < 0.05).ConclusionThe results indicated a relatively high prevalence of dead regions in children with sensory neural hearing impairment, especially for frequencies at which the hearing loss exceeds 70 dB HL.
