Possible role of neurointerventional techniques in the diagnosis of hemifacial spasm.

چکیده
We used neurointerventional techniques to conduct a functional investigation of the artery responsible for hemifacial spasm in a 48-year-old woman. Insertion of a microcatheter into the posterior inferior cerebellar artery stopped the hemifacial spasm immediately and completely. The artery was verified intraoperatively as the vessel compressing the root exit zone of the facial nerve.

Secondary or Symptomatic Hemifacial Spasm caused by a Tumor of Cerebellopontine Angle Case Report and Review of the Literature
Background & Importance: Primary hemifacial spasm is usually caused by microvascular compression of the facial nerve at its root exit zone at brainstem without any space-occupying pathology. Secondary or so-called symptomatic hemifacial spasm has an additional underlying pathology e.g. tumors leading to the microvascular compression. We review and discuss the pathophysiology and the literature ...
متن کاملHEMIFACIAL SPASM: A RERORT OF 100 CASES TREATED BY MICROVASCULAR DECOMPRESSION
100 patients with hemifacial spasm treated by microvascular decompression are presented. There were 60 females and 40 males. Their ages ranged from 29 to 75 years with a median age of 54 years, and the left side was involved predominantly. The common focal signs were facial nerve palsy in 41 cases, diminished hearing in 14 cases, trigeminal neuralgia in 11 cases, and homolateral trigeminal...
متن کاملRole of the "other Babinski sign" in hyperkinetic facial disorders.
BACKGROUND The "other Babinski sign" consists in the co-contraction of the orbicularis and frontalis muscles, causing an eyebrow elevation during ipsilateral eye closure. It cannot be voluntarily reproduced. AIMS OF THE STUDY To determine the utility of this sign in the differential diagnosis of hyperkinetic facial disorders. METHODS The presence of the sign was assessed in consecutive pati...
متن کاملComputed tomographic analysis of hemifacial spasm: narrowing of the posterior fossa as a possible facilitating factor for neurovascular compression.
Hemifacial spasm can be caused by vascular compression of the facial nerve at the root exit zone from the brainstem. Several case reports suggest that narrowing of the cerebellopontine angle cistern caused by Paget's disease, abnormal elevation of the petrous bone caused by hyperplasia, or contralateral acoustic neurinoma may increase the chance of vascular compression of the facial nerve. Ther...
متن کاملIntermittent facial spasms as the presenting sign of a recurrent pleomorphic adenoma
The intimate anatomical relationship of the facial nerve to the parotid parenchyma has a significant influence on the presenting signs and symptoms, diagnosis and treatment of parotid neoplasms. However, to our knowledge, hyperactivity of this nerve, presenting as facial spasm, has never been described as the presenting sign or symptom of a parotid malignancy. We report a case of carcinoma aris...
