In medicine, ablation is the removal of a part of biological tissue, usually by surgery. Surface ablation of the skin (dermabrasion, also called resurfacing because it induces regeneration) can be carried out by chemicals (chemoablation), by lasers (laser ablation), by freezing (cryoablation), or by electricity (fulguration).
Neurolysis is a chemical ablation technique that is used to alleviate pain. Neurolysis is only used when the disease has progressed to a point where no other pain treatments are effective. [ 1 ] A neurolytic agent such as alcohol, phenol, or glycerol is typically injected into the nervous system .
Percutaneous access and procedures frequently refer to catheter procedures such as percutaneous transluminal angioplasty (PTA) ballooning, stent delivery, filter delivery, cardiac ablation, and peripheral or neurovascular catheter procedures but also refers to a device that is implanted in the body, such as a heart pump (LVAD), and receives ...
Surgical ablation has been used to treat Parkinson's disease. In the 1990s, the pallidum was a common surgical target. Unilateral pallidotomy improves tremor and dyskinesia on one side of the body (opposite the side of the brain surgery), but bilateral pallidotomy was found to cause irreversible deterioration in speech and cognition .
The beam has the ability to pass through overlying tissues without harm and focus on a localized area with size limit of 2–3 mm, that is determined the clinical frequency of the ultrasound. Following ablation a distinct boundary forms between healthy and necrotic tissue (width less than 50 microns). [31]
Surgical or radiologic ablation of the carotid sinus nerve is used to treat carotid sinus hypersensitivity. [14] In a vagotomy, the vagus nerve is surgically removed to treat peptic ulcer disease by reducing stomach acid. [15] In a rhizotomy, nerve fibers in the spinal cord are destroyed with the intent of eliminating chronic myalgia. [16]

The superior cluneal nerves are pure sensory nerves that innervate the skin of the upper part of the buttocks. They are the terminal ends of the L1-L3 spinal nerve dorsal rami lateral branches. They are one of three different types of cluneal nerves (the middle and inferior cluneal nerves being the other two). They travel inferiorly through ...
