Abstract
The cochlear implant (CI) brings about an improvement in hearing quality and improvements in speech perception and production, rendering a permanent and ascending quality of life gain in many aspects such as self sufficiency and socialization. It is estimated that since the 70{u2019}s until today, there are 400 thousand implanted patients. The surgical implantation procedure via the transmastoid approach has been well standardized. There are two techniques placing CI electrode: cochleostomy or round window membrane (RWM). Less drilling is required in the RWM technique, thus reducing trauma, loss of perilymph, and bone powder. In this study, comparison between the RWM and the cochleostomy approach concerning some parameters, 1.time taken for full electrode insertion, 2.number of inserted channels, 3.attempts to fulfill a complete electrode insertion and finally 4. the neural response telemetry for all. Neural response telemetry (NRT) is a test used to measure electrically evoked compound action potentials (ECAP) during surgery or post- operatively in implanted patients. This is an important test used to accurately monitor external and internal hardware function, and assess cochlear stimulation through neural responses. Co work between otologists and audiologists is mandatory for better care of patients with success of cochlear implantation
