Summary
Otologic surgery can lead to new cases of benign paroxysmal positional vertigo (BPPV). This condition, often affecting the posterior semicircular canal, is manageable with repositioning maneuvers, even after drilling procedures.
Area of Science:
- Otolaryngology
- Neurosurgery
- Vestibular Disorders
Background:
- Benign paroxysmal positional vertigo (BPPV) is a common inner ear disorder.
- The relationship between otologic surgery and the onset of BPPV requires further investigation.
Purpose of the Study:
- To determine the incidence and clinical characteristics of new-onset BPPV following otologic surgery.
- To compare BPPV occurrence with and without surgical drilling during otologic procedures.
Main Methods:
- A retrospective review of 437 adult patients undergoing unilateral otologic surgery.
- Inclusion of patients diagnosed with BPPV within one month postoperatively.
Main Results:
- The overall incidence of postoperative BPPV was 2.28%.
- BPPV incidence was 3% with drilling and 1.16% without drilling (no significant difference).
- Symptoms typically presented as posterior semicircular canal canalolithiasis within 13 days, responding well to repositioning maneuvers.
Conclusions:
- Otologic surgery, particularly with drilling, is a potential risk factor for BPPV.
- Postoperative BPPV commonly involves the posterior SCC and is effectively treated with repositioning.
- Clinicians should monitor for BPPV in patients with vertigo post-otologic surgery.
