Abstract:
OBJECTIVE:To introduce a rat model for use in cochlear implant related research.
METHOD:Five deafened Hooded-Wistar rats were implanted with a scala tympani electrode array using a new surgical method. Electrically evoked brainstem responses (EABRs) using bipolar stimulation were recorded and cochlear history was assessed.
RESULT:Electrically evoked brainstem responses with normal configuration confirmed the functional status of the cochlear implantation. There was no evidence of severe insertion-induced damage of intra-cochlear structure.
CONCLUSION:The surgical method established in the rat model is a safe and effective procedure for acute or chronic cochlear implantation.
