The article reports that hemifacial spasm is a disorder characterized by intermittent, chronic, unilateral contractions of the facial musculature. Although hemifacial spasm has been recognized us a diagnostic entity, the basic pathophysiology of this syndrome is not established. The association of hemifacial spasm with a vascular lesion compressing the seventh nerve was first recorded 100 years ago. Since then, several authors have observed vascular abnormalities close to the intracranial seventh nerve in patients with hemifacial spasm.

    Object: The object of surgical treatment for hemifacial spasm (HFS) is the exclusion of pulsatile neurovascular compression of the root exit zone (REZ). However, spasm persists transiently or permanently in some cases even after complete decompression. In particular, we mainly experience these...

    Background: Surgeons often rely on intraoperative electrophysiological monitoring to determine whether decompression is sufficient during microvascular decompression surgery for hemifacial spasms. A new monitoring method is needed when an abnormal muscle response is occasionally not available or...

    Posterior segment anomalies are rare features of the oculoauriculovertebral complex. Our patient had hemifacial microsomia with an optic nerve hypoplasia in one eye and an optic nerve coloboma in the other eye. The optic nerve hypoplasia was ipsilateral to the side with hemifacial microsomia and...

    Complete restoration of facial asymmetry is always difficult to achieve. Facial asymmetry due to growth disturbances of the jaws almost requires orthognathic surgical correction, followed, in many cases, by soft tissue corrections. Mandibular hypoplasia is the earliest skeletal manifestation of...
