Vestibular Disorders after Stapedial Surgery in Patients with Otosclerosis

Area of Science:

• Otolaryngology
• Neurosurgery
• Vestibular Science

Background:

• Vertigo is a known complication following stapedial surgery.
• Research often focuses on hearing improvement, neglecting vestibular function assessment.
• Limited data exists on the prevalence and characteristics of vertigo post-stapedial surgery.

Purpose of the Study:

• To evaluate the incidence and nature of vertigo after stapedial surgery.
• To characterize the symptoms and severity of post-stapedial surgery vertigo.
• To assess the impact of stapedial surgery on vestibular function.

Main Methods:

• Prospective observational study design.
• Inclusion of patients undergoing stapedial surgery between October 2013 and December 2014.
• Assessment of vertigo using the Dizziness Handicap Inventory before and 4 months after surgery.

Main Results:

• 140 patients were included in the study.
• Pre-operative vertigo in 12 patients (8.6%) resolved post-surgery.
• New-onset vertigo was reported by 36 patients (25.7%) four months post-surgery.
• Postoperative vertigo scores ranged from 2 to 18 points.

Conclusions:

• Vestibular disturbances can persist beyond the immediate post-operative phase.
• A significant percentage of patients develop new-onset vertigo after stapedial surgery.
• Enhanced patient clarification regarding vestibular risks in informed consent is crucial.
