Subjective Visual Vertical Can be an Effective Tool to Evaluate Vestibular Function of Stapedotomy

To investigate if the subjective visual vertical/horizontal (SVV/SVH) can be used to evaluate the otolith organ of otosclerosis and stapedotomy.

SVV/SVH measurement appears to be a feasible tool for monitoring otolith organ function perioperatively in otosclerosis patients undergoing stapedotomy, but independent replication in larger samples is needed before it should alter routine vestibular assessment protocols.

Adding a simple, non-invasive SVV test to stapedotomy evaluations could help clinicians detect subtle vestibular changes that current standard hearing assessments miss.

1. 01SVV/SVH testing was used to assess otolith organ function in otosclerosis patients pre- and post-stapedotomy.
2. 02Otosclerosis can affect not just hearing but also the vestibular (balance) system via otolith organ involvement.
3. 03Stapedotomy is a middle-ear surgical procedure that replaces the fixed stapes bone with a small prosthesis.
4. 04The study supports SVV as a practical, non-invasive vestibular screening tool in this surgical population.
5. 05Findings suggest the otolith organs may be affected by otosclerosis and monitored through perceptual balance tests.
