Summary
Labyrinthine fistulas can cause vertigo and sudden hearing loss, especially during exertion. Early surgical closure is recommended after conservative therapy for diagnosis and treatment.
Area of Science:
- Otolaryngology
- Neurosurgery
Background:
- Labyrinthine fistula of the round window is a rare condition.
- It presents with vertigo and sudden hearing loss, often exacerbated by physical stress or exertion.
- Differential diagnosis includes other causes of vertigo and hearing loss.
Observation:
- Five patients with suspected labyrinthine fistula were evaluated.
- Four patients underwent surgical exploration and closure.
- One patient received an expert opinion.
Findings:
- Surgical exploration is the definitive diagnostic and therapeutic method for labyrinthine fistulae.
- Spontaneous healing can occur, but early surgical intervention is often recommended.
- Conservative therapy may precede surgery.
Implications:
- Consider labyrinthine fistula in patients with unexplained vertigo and sudden hearing loss.
- Prompt surgical intervention can lead to successful outcomes.
- This condition requires careful consideration in the differential diagnosis of inner ear disorders.
