Summary
Stapes surgery can cause vestibular issues, leading to spontaneous nystagmus. This study evaluated vestibular damage after stapes surgery using portable electroNystagmography (ENG).
Area of Science:
- Otolaryngology
- Neurosurgery
- Vestibular System
Background:
- Hearing outcomes after stapes surgery are well-documented.
- Risks of vestibular disturbance following stapes surgery require further investigation.
Purpose of the Study:
- To evaluate vestibular damage after stapes surgery.
- To assess postoperative spontaneous nystagmus using portable electroNystagmography (ENG).
Main Methods:
- Thirteen patients undergoing primary stapedotomy or stapedectomy were monitored.
- Postoperative spontaneous nystagmus was measured daily via bedside portable ENG.
Main Results:
- Nystagmus was observed in 9 out of 13 patients.
- Nystagmus patterns varied, including toward the operated ear, opposite ear, or changing directions.
- No correlation was found between nystagmus duration and dizziness duration.
Conclusions:
- Stapes surgery poses a risk of vestibular damage, manifesting as postoperative nystagmus.
- Potential causes include inner ear trauma, perilymphatic fistula, footplate issues, and potassium ion effects.
- Further research is needed to fully understand and mitigate these vestibular risks.
