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.
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.
Meige's is commonly misdiagnosed and most doctors will not be familiar with this condition due to its rare incidence. Usually, a neurologist specializing in psychomotor disorders can detect Meige's. There are currently no technological diagnostic tools to detect Meige's, as it cannot be identified using blood chemistry analysis or radiological ...
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]
Chang has made fundamental contributions to understanding the neural code of speech and neuropsychiatric conditions in the human brain. [5]Chang pioneered the use of high-density direct electrophysiological recordings from cortex, which enabled him and colleagues to determine the selective tuning of cortical neurons to specific acoustic and phonetic features in consonants and vowels.

Cost: $7 | Active ingredients: Lidocaine | Type: Cream | Amount: 4.3 ounces. Lidocaine is another popular ingredient found in pain relief creams. It's a topical anesthetic that's often used to ...
By 1982, eye muscles had been injected for strabismus and nystagmus (jerky, involuntary eye movements), eyelid muscles for retraction and blepharospasm (sustained, involuntary contractions of muscles around the eye), facial muscles for hemifacial spasm, and limb muscles for dystonia (sustained muscle spasm), all as predicted in Scott's 1973 study.
Møller found evidence that the spasm was created by the facial motor nucleus probably through the process of activation of neuroplasticity and not by the pathologies of the facial nerve where it was in contact with a blood vessel. [17] These studies also improved the outcome of operations for hemifacial spasm.
