Robotic Versus Manual Electrode Insertion in Cochlear Implant Surgery: An Experimental Study.

Objectives: This experimental study compares the precision and surgical outcomes of manual versus robotic electrode insertions in cochlear implantation.

Methods: Conducted on formalin-fixed cadaveric heads, the study involved nine senior neurotologists performing both manual and robotic insertions.

Results: The results showed no statistically significant difference between the two methods in insertion angle, cochlear coverage, or electrode coverage.

Cochlear nerve visualization in Normal anatomy and inner ear malformations.

Objectives: This study aimed to qualitatively evaluate the variations in nerve bundles between patients with normal anatomy and those with inner-ear anomalies.

Methods: Magnetic resonance imaging (MRI) scans of the temporal bones of candidates for cochlear implants (CIs) enrolled at a tertiary center were retrospectively reviewed from the clinical database. The 3.

Estimation of outer-wall length in optimizing cochlear implantation in malformed inner ears.

Estimation of cochlear length is gaining attention in the field of cochlear implants (CIs), mainly for selecting of CI electrode lengths. The currently available tools to estimate the cochlear duct length (CDL) are only valid for normal inner anatomy. However, inner ear malformation (IEM) types are associated with different degrees of cystic apices, limiting the application of CDL equations of normal anatomy inner ear.

Amplitude Parameters Are Predictive of Hearing Preservation in a Randomized Controlled Trial of Intracochlear Electrocochleography During Cochlear Implant Surgery.

Objective: To prospectively evaluate the association between hearing preservation after cochlear implantation (CI) and intracochlear electrocochleography (ECochG) amplitude parameters.

Study Design: Multi-institutional, prospective randomized clinical trial.

Setting: Ten high-volume, tertiary care CI centers.

Cochlear Implantation: Long-Term Effect of Early Activation on Electrode Impedance.

: The growing adoption of cochlear implants (CIs) necessitates understanding the factors influencing long-term performance and improved outcomes. This work investigated the long-term effect of early activation of CIs on electrode impedance in a large sample of CI users at different time points. : A retrospective study on 915 ears from CI patients who were implanted between 2015 and 2020.
