Detection of hearing loss in young children and adults using otoacoustic emissions.

Measures of transient evoked otoacoustic emission (TEOAE) reproducibility were obtained for 506 ears of 260 children and young adults. Frequency-specific and whole reproducibility data were obtained using ILO88 hardware and software (version 3.92), and were analyzed with respect to pure tone threshold and emmittance data for the same ears. The 2,000-Hz reproducibility score was the most efficient of all measurements (0.85-0.91) in separating normal and hearing-impaired ears, regardless of the frequencies at which the hearing loss occurred. TEOAE reproducibility measures may be very useful in screening for hearing loss in babies, leading to the earliest identification of children with hearing loss.

Progressive sensorineural hearing loss in survivors of persistent fetal circulation.

The purpose of this study was to discover whether sensorineural hearing loss was a significant complication in survivors of persistent fetal circulation. Eleven patients were followed to 36 months. Hearing assessments were performed on at least two occasions using brain stem auditory evoked response testing and behavioral audiometry. Three of 11 babies had bilateral, progressive sensorineural hearing loss. No clear relationship could be found between hearing loss and any of the clinical variables examined in this study.

Sickle cell anemia and hearing.

The present investigation examined the effects of sickle cell anemia on threshold hearing. The study included 43 homozygous sickle cell anemia patients, ages 7-18 years, and 23 age-matched controls with documented normal hemoglobin. Both the study and control groups received otologic and audiologic examinations. Bilaterally normal hearing was found in 88% of the sickle cell subjects. Unilateral or bilateral mild high frequency sensorineural hearing loss was demonstrated in 12% (5 of 43). The control subjects revealed no hearing loss. The sickle cell group, therefore, exhibited a higher than usual incidence of hearing loss. Further, three of the five subjects with hearing loss evidenced central nervous system involvement, resulting in a probability of < 0.025 that this relation might occur by chance. Periodic hearing evaluations of children with sickle cell anemia should be performed to identify those with auditory complications and those who possibly may have CNS involvement.
