Hearing 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...

Factors affecting residual hearing preservation in cochlear implantation

The likelihood of residual hearing preservation in cochlear implantation (CI) is related to surgical factors such as type of cochleostomy (trans-fenestral vs. promontorial), use of lubricants and protective drugs, and device-related factors such as shape, length and flexibility of the array. We investigated the impact of these factors on the hearing preservation rate in adults and children with...

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...

Hearing Preservation in Cochlear Implant Surgery

In the past, it was thought that hearing loss patients with residual low-frequency hearing would not be good candidates for cochlear implantation since insertion was expected to induce inner ear trauma. Recent advances in electrode design and surgical techniques have made the preservation of residual low-frequency hearing achievable and desirable. The importance of preserving residual low-frequ...
