Long-term evaluation of the effect of intracochlear steroid deposition on electrode impedance in cochlear implant patients.

Objective: To evaluate the long-term effect of intracochlear steroid deposition on electrode impedance in patients with cochlear implants.

Study Design: A retrospective study was carried out comparing the impedances of cochlear implant electrodes with and without a single application of steroids in the cochlea.

Patients: Ninety two implanted children with an average age of 5 years (range, 0.

Postural stability of preoperative acoustic neuroma patients assessed by sway magnetometry: are they unsteady?

Objective: The objective was to evaluate the preoperative postural stability of acoustic neuroma patients using sway magnetometry.

Study Design: Prospective two-center study.

Methods: Fifty-one patients (mean age, 53 years) diagnosed with unilateral acoustic neuroma on magnetic resonance imaging at two tertiary referral centers were studied.
