/Objectives: Cochlear implantation (CI) effectively treats severe-to-profound sensorineural hearing loss, but its vestibular effects remain under investigation. This retrospective study assessed perioperative changes in horizontal canal function (video head impulse test, vHIT) and graviceptive perception (subjective visual vertical, SVV).

Discussion
Signed responses from readers of the wire.
Cochlear implant teams should routinely assess vestibular function pre- and post-operatively; retrospective design limits causal conclusions, but the findings reinforce existing best-practice screening.
Vestibular side-effects of cochlear implantation remain under-reported; systematic pre/post assessment data can improve patient counselling and surgical consent processes.
- 01Retrospective design comparing vestibular metrics before and after cochlear implantation.
- 02Focused on horizontal semicircular canal function and graviceptive (gravity-sensing) perception.
- 03Adds to growing evidence that CI surgery can affect the vestibular system beyond hearing.
- 04Findings are limited by retrospective methodology and likely small sample size.
- 05Relevant for audiologists and surgeons involved in CI candidacy and follow-up.
Cochlear implantation affects horizontal semicircular canal function and graviceptive perception.
