Hypothesis: Modiolar proximity of the cochlear implant electrodes and low impedance values have a positive effect on electrical pitch discrimination. Background: The proximity of the cochlear electrode to the modiolar wall can determine changes in tissue and fluid environment. With the onset of soft-surgery techniques, the trauma caused during surgery has been reduced, minimizing fibrous growth. Methods: Computed tomography-scan measurements of electrode-inner wall distance and psychoacoustic electrode discrimination tests were done. Neural Response Telemery and impedance data were used in the study. Results: It was found that patients fitted with perimodiolar arrays have lower impedance values and smaller electrodeinner wall distances than those fitted with straight arrays. These variables were significantly correlated to electrode discrimination. It was found that a closer distance to the modiolus also results in better electrode discrimination. Conclusion: Perimodiolar electrodes could be a better solution in terms of pitch discrimination both because they are closer to the modiolus and because their impedance is lower.

The purpose of this study is to determine if surgical approach to the inner ear is feasible without generating a hearing loss in an animal model. Five Macaca fascicularis were used as experimental animals and followed up for 27 months. Mastoidectomy, posterior tympanotomy and promontorial cochleostomy were performed on four specimens and one specimen was kept as control animal. Before and after drilling and exposing the endosteal layer and the membranous labyrinth, otoacustic emissions (dPOAE) and auditory brainstem responses (ABR) were used to test hearing. In vivo experimental studies prove it is reliable to expose the membranous labyrinth without causing hearing loss. dPOAE were present after 3, 6, 12, 24 and 26 months of follow-up. Regarding the ABR results from the four M. fascicularis in which a cochleostomy has been carried out, auditory thresholds are within the 20-30 dB interval at 27 months of follow-up. Experimental studies support clinical experiences indicating it is feasible to surgically approach the membranous labyrinth of the cochlea without damaging its hearing function.

The treatment of patients with idiopathic sudden sensorineural hearing loss must be performed as an emergency measure in order to prevent long term hearing deficit. Steroids in monotherapy provide the best outcome. There is some controversy regarding the most efficient route but in order to prevent side effects, intratympanic treatment is the preferred choice, especially in diabetic patients. We here present the case of a patient that developed hyperglycemia after systemic and intratympanic dexamethasone treatment for sudden hearing loss. We conclude that after intratympanic treatment great caution must be taken.

The findings of our study both agree and disagree with some earlier works from the literature, which suggests that patients with AD may have their own auditory pattern.
