Hemifacial spasm (HFS) is a rare neuromuscular disease characterized by irregular, involuntary muscle contractions on one side (hemi-) of the face (-facial). [1] The facial muscles are controlled by the facial nerve (seventh cranial nerve), which originates at the brainstem and exits the skull below the ear where it separates into five main branches.
Microvascular decompression (MVD), also known as the Jannetta procedure, [1] is a neurosurgical procedure used to treat trigeminal neuralgia (along with other cranial nerve neuralgias), a pain syndrome characterized by severe episodes of intense facial pain, and hemifacial spasm.
Oromandibular dystonia (OMD) is a form of focal dystonia that affects varying areas of the head and neck including the lower face, jaw, tongue and larynx. The spasms may cause the mouth to pull open, shut tight, or move repetitively. Speech and swallowing may be distorted.
Oromandibular dystonia is characterized by involuntary spasms of the tongue, jaw, and mouth muscles that result in bruxism, or grinding of the teeth, and jaw closure. These conditions frequently lead to secondary dental wear as well as temporomandibular joint syndrome. In addition, problems with chewing, speaking, and swallowing may result from ...
The Chvostek sign (/ ˈ k v ɒ s t ɪ k /) is a clinical sign that someone may have a low blood calcium level (a decreased serum calcium, called hypocalcemia).The Chvostek sign is the abnormal twitching of muscles that are activated (innervated) by the facial nerve (also known as Cranial Nerve Seven, or CNVII).

Most people with Bell's palsy start to regain normal facial function within three weeks—even those who do not receive treatment. [47] In a 1982 study, when no treatment was available, of 1,011 patients, 85% showed first signs of recovery within three weeks after onset. For the other 15%, recovery occurred 3–6 months later.
These studies also improved the outcome of operations for hemifacial spasm. In the late 1970s and early 1980s, Møller was one of the founders of a new subspecialty of neurological surgery and orthopedic surgery that is now known as Intraoperative neurophysiological monitoring (IONM). The purpose of this subspecialty is to reduce the risk of ...
Neuro-ophthalmology is mostly non-procedural, however, neuro-ophthalmologists may be trained to perform eye muscle surgery to treat adult strabismus, optic nerve fenestration for idiopathic intracranial hypertension, and botulinum injections for blepharospasm or hemifacial spasm. [5]
