Hearing Preservation After Penetrating Cochlear Injury.
OBJECTIVES To share results and recommendations for management of penetrating cochlear injury. METHODS A patient underwent repair of a penetrating cochlear injury after a projectile led to a traumatic cochleostomy with a narrow miss of the facial nerve and intracranial carotid artery. RESULTS Postoperatively, the patient's audiogram demonstrated a pure tone average of 47.5 dB for air conduc...
متن کاملHearing Preservation after Cochlear Implantation: UNICAMP Outcomes
Background. Electric-acoustic stimulation (EAS) is an excellent choice for people with residual hearing in low frequencies but not high frequencies and who derive insufficient benefit from hearing aids. For EAS to be effective, subjects' residual hearing must be preserved during cochlear implant (CI) surgery. Methods. We implanted 6 subjects with a CI. We used a special surgical technique and a...
متن کاملCochlear implants for children with severe-to-profound hearing loss.
Copyright © 2007 Massachusetts Medical Society. A 4-month-old baby girl whose parents and 6-year-old brother have severe-to-profound sensorineural hearing loss is referred for consideration for cochlear implantation. Each of the baby’s parents had previously received a cochlear implant in adulthood, and her older brother had received a cochlear implant at 18 months of age. The family uses oral ...
متن کاملCochlear Implants and Hearing Preservation Advances in Oto-Rhino-Laryngology
Hearing preservation after cochlear implantation and combined electric acoustic stimulation (EAS) in the same ear has reduced the gap between prosthetic hearing rehabilitation with hearing aids and cochlear implants. This has increased the possibility of successful hearing rehabilitation for patients. This paper describes the history of hearing preservation after cochlear implantation. Indicati...
متن کاملWith Normal Hearing and Cochlear Hearing Loss
Distortion product emissions (DPEs) at 2f1 f2 frequencies were measured in 53 human ears; 21 of them exhibited cochlear hearing loss. DPEs were obtained as a function of stimulus level (DPE growth curves) at seven frequency regions between 707 Hz and 5656 Hz. Several distinctly different shapes or patterns of DPE growth curves were observed. These included single-segment monotonic growth curves...
