Drop attacks in Menière's disease
1Department of Otolaryngology, University Hospital, Linköping, Sweden.
Abstract:
An inner ear etiology for drop attacks is easily overlooked and seldom mentioned in the literature. Cardiovascular pathology is what generally is looked for, e.g. transitory ischemic attacks. Twenty-nine patients with frequent and severe Meniere attacks were treated with gentamicin intratympanally, when they had reached a stage of incapacitation due to vertigo and dread of further attacks and all medical treatments had failed. All but one patient were suffering from more or less frequent drop attacks. The attacks of vertigo were successfully cured in all patients except 2, who had recurrence of the inner ear problem. The drop attacks disappeared in all patients, which indicates that they had an inner ear origin.
Insights
Inner ear conditions, like Meniere disease, can cause incapacitating drop attacks. Intratympanic gentamicin effectively cured drop attacks in Meniere disease patients, confirming an inner ear origin.
Area of Science:
- Otolaryngology
- Neurology
Background:
- Drop attacks are often misdiagnosed, with cardiovascular causes frequently investigated over inner ear pathologies.
- Inner ear etiology for drop attacks is underrepresented in medical literature.
- Meniere disease can present with severe vertigo and incapacitating drop attacks.
Purpose of the Study:
- To investigate the efficacy of intratympanic gentamicin in treating drop attacks associated with Meniere disease.
- To determine if drop attacks in Meniere disease patients originate from the inner ear.
Main Methods:
- Twenty-nine patients with severe, incapacitating Meniere attacks and frequent drop attacks were treated with intratympanic gentamicin.
- Treatment was administered after failure of all other medical interventions.
Main Results:
- Vertigo attacks were resolved in all but two patients.
- All patients experienced complete resolution of drop attacks, strongly suggesting an inner ear origin.
- Two patients experienced recurrence of inner ear symptoms.
Conclusions:
- Intratympanic gentamicin is an effective treatment for incapacitating drop attacks in Meniere disease.
- The complete resolution of drop attacks supports an inner ear etiology for these events in Meniere disease patients.
