Hemifacial spasm (HFS) is a peripheral movement disorder caused by direct or indirect compression or distortion of the root exit zone of the seventh cranial nerve, which is most commonly compressed by an arterial loop, but also may be compressed by a tumor, cyst, or aneurysm.

A review of the literature as well as recent surgical observations indicate that hemifacial spasm may be caused by normal or pathological vascular structures that cross-compress the facial nerve. The critical area of compression is invariably found at the brain stem exit zone of the seventh cranial nerve.

Three male patients in successive generations of the same family developed acquired left-sided hemifacial spasm. Magnetic resonance imaging of the proband demonstrated a pontine vertebral artery anomaly near the root of the affected facial nerve. This family and a similar family that was recently presented illustrate several interesting features: (1 ...

Hemifacial spasm (HFS) is a peripherally induced movement disorder causing clonic or tonic contractions of the facial muscles. HFS is usually unilateral and sporadic. It may be primary (mainly attributed to vascular compressions of the seventh cranial nerve in the posterior fossa) or secondary to facial nerve or brainstem damage.

Hemifacial spasm in a 10-year-old child is herein reported. Computed tomography and angiography were normal. Magnetic resonance imaging showed an anomalous vascular structure, probably a redundant loop arising from AICA or PICA, which was identified at surgery. The spasm, presumably due to vascular compression at the root entry zone of the right facial

Three infants presented with the onset of hemifacial spasm after birth and at the age of 10 months. One patient was found to have occlusion of the straight sinus and large collateral veins at the base of the brain, presumably due to venous sinus thrombosis, supporting the concept of vascular compression of the facial nerve at its exit from the brain ...

We conducted polygraphic studies during wakefulness and all-night sleep in 13 patients with cryptogenic and 3 with postparalytic hemifacial spasm. The movements decreased progressively with deepening sleep stages, reaching lowest values in REM sleep. The reduction was inversely related to the severity of movements during wakefulness.

A 6-week-old infant had recurrent contractions of the facial musculature on the left side, which continued throughout early childhood. Surgical exploration at 5 1/2 years of age revealed a ganglioneuroma of the fourth ventricle. Hemifacial spasm (HFS) in infancy and childhood suggests the possibility of serious intracranial pathologic findings.

Among 155 cases of hemifacial spasm (HFS), the authors found two cases of atypical HFS (1.3%) in which spasm started with the orbicularis oris and buccinator muscles, and gradually spread upward to involve the orbicularis occuli muscle, whereas the reverse process is usually seen in cases of typical HFS. The compression site in cases of atypical HFS is

Facial spasms that distort facial expression are typically due to facial dystonia, tics, and hemifacial spasm (HFS). Psychogenic facial spasms, however, have not been well characterized. The authors sought to 1) determine prevalence of psychogenic facial spasm in patients referred for evaluation of HFS and 2) draw attention to clinical characteristics ...
