Introduction: The study of trigeminal surgery is linked to neuralgia and being a serious disorder can impair the patient's quality life. Objective: To analyze literature on relevant aspects surgery, such as decompression, sensitivity, anesthesia schwannomas. Methodology: PubMed, SCOPUS Google Scholar databases were reviewed find recent articles published with following keywords: “trigeminal ner...

OBJECTIVE Microvascular compressions of the cochlear nerve can lead to tinnitus. The tinnitus initially is related to nonsynchronous signal transmission in the auditory nerve, neurophysiologically characterized by a peak II amplitude decrease. Chronic compression can lead to a focal demyelination, resulting in an increase in Iinterpeak latency I-III with tinnitus and frequency-specific hearing ...

Hemifacial spasm is a socially disabling condition that manifests as intermittent involuntary twitching of the eyelid and progresses to muscle contractions of the entire hemiface. Patients receiving microvascular decompression of the facial nerve demonstrate an abnormal lateral spread response (LSR) in peripheral branches during facial electromyography. The authors retrospectively evaluate the ...

Our purpose is to report a case of trigeminal neuralgia caused by vertebrobasilar dolichoectasia treated with microvascular decompression. A 63-year-old man sought treatment for a recurrent lancinating left facial pain in V2 and V3 trigeminal territories. The computed tomography angiography revealed a mechanical compression of the left trigeminal nerve due to vertebrobasilar dolichoectasia. The...

The present research investigated the role of blood viscosity on flow within a microvascular network to identify the conditions of blood flow stagnation. When the yield stress of blood was less than 0.005 Pa, there were no stagnant regions in the microvasculature. However, when the yield stress increased to 0.05 Pa, stagnant or reduced flow areas began to appear, which grew and expanded rapidly...

OBJECTIVES Approximately 8000 patients with trigeminal neuralgia undergo surgery each year in the United States at an estimated cost exceeding $100 million. We compared 3 commonly performed surgeries (microvascular decompression, glycerol rhizotomy, and stereotactic radiosurgery) to evaluate the relative cost-effectiveness of these operations for patients with idiopathic trigeminal neuralgia. ...

Neurovascular compression syndrome is generally caused by vascular at the root entry or exit zone of corresponding cranial nerve. Trigeminal neuralgia most frequent syndrome, followed hemifacial spasm. Despite ongoing debate in literature, pulsatile tinnitus also known to be a neurovascular resulting from vestibulocochlear Combined manifestations symptoms are very rare. We report case with simu...

Eleven patients with intractable trigeminal neuralgia were treated by posterior fossa microvascular decompression. Complete pain relief was achieved in 7 patients (63.3%). Partial relief of symptoms was noted in 3 patients (27%). There was no operative mortality. Two patients developed transient lower cranial nerve palsies whereas one patient developed a CSF leak, requiring treatment by lumbar ...
