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. The procedure is also used experimentally to treat tinnitus and ...
The trigeminal nerve is a paired cranial nerve that has three major branches: the ophthalmic nerve (V 1), the maxillary nerve (V 2), and the mandibular nerve (V 3). One, two, or all three branches of the nerve may be affected. Trigeminal neuralgia most commonly involves the middle branch (the maxillary nerve or V 2) and lower branch (mandibular ...
t. e. In neuroanatomy, the trigeminal nerve (lit. triplet nerve), also known as the fifth cranial nerve, cranial nerve V, or simply CN V, is a cranial nerve responsible for sensation in the face and motor functions such as biting and chewing; it is the most complex of the cranial nerves. Its name (trigeminal, from Latin tri- 'three' and ...
ICD-9-CM. 03.1. MeSH. D019051. [edit on Wikidata] A selective dorsal rhizotomy (SDR), also known as a rhizotomy, dorsal rhizotomy, or a selective posterior rhizotomy, is a neurosurgical procedure that selectively cuts problematic nerve roots in the spinal cord. [3][note 1] This procedure has been well-established in the literature as a surgical ...
The great auricular nerve is a large trunk that ascends almost vertically over the sternocleidomastoid. [2] It winds around the posterior border of the sternocleidomastoid muscle, then perforates the deep fascia before ascending alongside the external jugular vein upon that sternocleidomastoid muscle beneath the platysma muscle to the parotid gland.

[46] Family cases are frequent, in a range from 25% to 66% without any clear mode of inheritance." [26] IH has long been considered a rare disease, believed to be 10 times less frequent than narcolepsy. [26] The prevalence of narcolepsy (with cataplexy) is estimated between 1/3,300 and 1/5,000.

The foramen ovale is used as the entry point into the skull when conducting a Percutaneous Rhizotomy using either radio-frequency ablation, balloon compression or glycerol injection. These are performed to treat trigeminal neuralgia. In the procedure, the electrode is introduced through the cheek of an anesthetized patient and radiologically ...
Current Procedural Terminology. The Current Procedural Terminology (CPT) code set is a procedural code set developed by the American Medical Association (AMA). It is maintained by the CPT Editorial Panel. [1] The CPT code set describes medical, surgical, and diagnostic services and is designed to communicate uniform information about medical ...
