Tinnitus Outcome in Surgery for Vertigo

Area of Science:

• Otolaryngology
• Neurosurgery
• Audiology

Background:

• Meniere's disease frequently causes disabling vertigo and bothersome tinnitus.
• Surgical interventions are considered for intractable vertigo in Meniere's disease.
• The impact of different vertigo surgeries on tinnitus symptoms is not well-defined.

Purpose of the Study:

• To evaluate the effect of three distinct vertigo surgeries on tinnitus.
• To compare the tinnitus outcomes between destructive labyrinthectomy, endolymphatic sac decompression and shunt, and vestibular neurectomy.

Main Methods:

• A cohort of 90 patients with Meniere's disease undergoing surgery for vertigo was studied.
• Procedures included destructive labyrinthectomy, endolymphatic sac decompression and shunt, and vestibular neurectomy.
• Tinnitus outcomes were assessed post-surgery, and correlated with surgical type and preoperative hearing loss.

Main Results:

• Vestibular neurectomy demonstrated a significantly better tinnitus outcome (50%) compared to endolymphatic sac shunt surgery (22.7%).
• Destructive labyrinthectomy and vestibular neurectomy groups showed comparable positive tinnitus response rates (50%).
• Preoperative hearing loss severity did not correlate with tinnitus outcomes across all surgical groups.

Conclusions:

• Vestibular neurectomy appears more effective for tinnitus control in Meniere's disease patients with vertigo and serviceable hearing.
• Patients requiring vertigo surgery should consider vestibular neurectomy for a potentially better tinnitus outcome over shunt procedures.
• Further research may elucidate the mechanisms underlying tinnitus modulation by different surgical approaches for vertigo.
