Objective: The current study aims to investigate whether objective measurements of the cochlear nerve (CN), derived from preoperative MRI images, correlate with postoperative speech perception in CI patients.
Study Design: Retrospective cohort study.
Setting: University Medical Center, tertiary academic referral center.
Purpose: Patients with age-related hearing loss complain often about reduced speech perception in adverse listening environment. Studies on animals have suggested that cochlear synaptopathy may be one of the primary mechanisms responsible for this phenomenon. A decreased wave I amplitude in supra-threshold auditory brainstem response (ABR) can diagnose this pathology non-invasively.

Whether to use a shorter electrode length under the aim of structure preservation versus choosing a longer array to achieve a greater cochlear coverage is a matter of debate. The aim of this review is to identify the impact of the insertion depth of a cochlear implant (CI) electrode array on CI users' speech perception outcomes.

Traditionally, postoperative radiological imaging has been used to assess electrode position. Transimpedance matrix (TIM) measurements have also emerged as a promising method for assessing electrode position.

- Systemic glucocorticoids, like prednisolone and dexamethasone, are often used to treat idiopathic sudden sensorineural hearing loss (ISSNHL), but it's unclear if higher doses are more effective or riskier than lower doses.
- In a study with 325 patients, groups were given different regimens: high-dose intravenous prednisolone, high-dose oral dexamethasone, or lower-dose oral prednisolone.
- Results showed that while there were improvements in hearing, high-dose therapies (HD-Pred and HD-Dex) did not outperform lower-dose treatment (Pred-Control) and were associated with more adverse side effects.
