Radiofrequency ablation (RFA), also called fulguration, [1] is a medical procedure in which part of the electrical conduction system of the heart, tumor, sensory nerves or a dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz).
Neuroablation can be performed with chemical neurolysis or radiofrequency ablation. These techniques are often used on the medial branch nerves to treat low back pain and have been applied to the superior cluneal nerves. The use of phenol has been noted to relieve pain for up to 9 months but may not completely resolve symptoms. [5]
While under the trapezius, the medial branch of the posterior division of the third cervical nerve gives off a branch called the third occipital nerve (also known as the least occipital nerve), which pierces the Trapezius and ends in the skin of the lower part of the back of the head.
Radiofrequency ablation or lesioning, also known as rhizolysis, can be used to give longer lasting relief by destroying the nerves that supply the facet joint (medial branch nerves). [9] Current guidelines as per the International Spine Intervention Society require two successful medial branch blocks before progressing to a radiofrequency ablation.
A vestibular neurectomy is an operation that severs the vestibular nerve, which contributes to balance, while sparing the cochlear nerve, which contributes to hearing. The procedure has the potential to relieve vertigo, but may preserve the ability to hear. [7] It is important to note that this procedure will not reverse the effects of deafness.
The greater occipital nerve is a nerve of the head. It is a spinal nerve, specifically the medial branch of the dorsal primary ramus of cervical spinal nerve 2.It arises from between the first and second cervical vertebrae, ascends, and then passes through the semispinalis muscle.
Cervical facet joint block – minor injections at the joints of the affected regions of the cervical spine; Media branch block and radio-frequency ablation – diagnosis and alleviation of pain from specific medial branches of the spinal nerve upon administering anaesthetics in the cervical region of interest to locate the area for treatment ...
The medial supraclavicular nerves or anterior supraclavicular nerves (nn. supraclaviculares anteriores; suprasternal nerves) cross obliquely over the external jugular vein and the clavicular and sternal heads of the sternocleidomastoideus, and supply the skin as far as the middle line. They furnish one or two filaments to the sternoclavicular ...
