Successful Treatment of Blepharospasm by Pallidal Neurostimulation
نویسندگان
چکیده
Blepharospasm, a focal dystonia characterized by involuntary orbicularis oculi muscle spasms, may vary in severity from a slightly bothersome condition to a disabling disorder that renders patients functionally blind. Botulinum toxin (BTX) injection, the gold-standard treatment, has a beneficial effect in 95% of patients. Oral medication is of limited efficacy. For individuals that do not respond, eyelid myectomy or upper-lid orbicularis muscle strip with subsequent eyebrow suspension are possible therapeutic options, although not always with acceptable results. Herein, we present the first case report of globus pallidus interna (GPi)-DBS surgery for isolated blepharospasm.

Intractable Blepharospasm Treated with Bilateral Pallidal Deep Brain Stimulation
BACKGROUND Blepharospasm can be present as an isolated dystonia or in conjunction with other forms of cranial dystonia, causing significant disability. CASE REPORT We report a case of a 69-year-old male with craniocervical dystonia, manifesting primarily as incapacitating blepharospasm refractory to medical treatments. He underwent bilateral globus pallidus (GP) deep brain stimulation (DBS) w...
متن کاملPallidal neurostimulation in patients with medication-refractory cervical dystonia: a randomised, sham-controlled trial.
BACKGROUND Cervical dystonia is managed mainly by repeated botulinum toxin injections. We aimed to establish whether pallidal neurostimulation could improve symptoms in patients not adequately responding to chemodenervation or oral drug treatment. METHODS In this randomised, sham-controlled trial, we recruited patients with cervical dystonia from centres in Germany, Norway, and Austria. Eligi...
متن کامل[Costs and efficacy of type A botulinum toxin for the treatment of essential blepharospasm and hemifacial spasm].
PURPOSE To evaluate the costs and efficacy of type A botulinum toxin in the treatment of essential blepharospasm and hemifacial spasm. METHODS Pacients with essential blepharospasm and hemifacial spasm had their files analyzed. All patients were treated with type A botulinum toxin (Dysport) between April 2002 and May 2004 at the Oculoplastic Clinics of "Santa Casa de São Paulo". Twenty-seven ...
متن کاملProfile of Xeomin® (incobotulinumtoxinA) for the treatment of blepharospasm
Even though conventional botulinum neurotoxin (BoNT) products have shown successful treatment results in patients with benign blepharospasm (BEB), the main, potential long-term side effect of BoNT use is the development of immunologic resistance due to the production of neutralizing antibody to the neurotoxin after repeated injections. Xeomin(®) (incobotulinumtoxinA), a unique botulinum neuroto...
متن کاملHypokinesia upon Pallidal Deep Brain Stimulation of Dystonia: Support of a GABAergic Mechanism
In the past, many studies have documented the beneficial effects of deep brain stimulation (DBS) in the globus pallidus internus for treatment of primary segmental or generalized dystonia. Recently however, several reports focused on DBS-induced hypokinesia or freezing of gait (FOG) as a side effect in these patients. Here we report on two patients suffering from FOG after successful treatment ...
