The stellate ganglia may be cut in order to decrease the symptoms exhibited by Raynaud's phenomenon and hyperhydrosis (extreme sweating) of the hands. Injection of local anesthetics near the stellate ganglion can sometimes mitigate the symptoms of sympathetically mediated pain such as complex regional pain syndrome type I (reflex sympathetic dystrophy), and symptoms associated with alterations ...
Horner's syndrome, also known as oculosympathetic paresis, [1] is a combination of symptoms that arises when a group of nerves known as the sympathetic trunk is damaged. The signs and symptoms occur on the same side (ipsilateral) as it is a lesion of the sympathetic trunk.
The treatment is known as SGB (stellate ganglion block), which can also be referred to as CSB (cervical sympathetic blockade). The stellate ganglion is treated with an injection of local anesthetic (numbing medicine) to block the sympathetic nerves located on either side of the voice box in the neck.

Because ganglionic blockers block both the parasympathetic nervous system and sympathetic nervous system, the effect of these drugs depends upon the dominant tone in the organ system. [2] The opposite of a ganglionic blocker is referred to as a ganglionic stimulant. Some substances can exhibit both stimulating and blocking effects on autonomic ...
There are usually 22–23 pairs of these ganglia: three cervical ganglia, 12 thoracic ganglia (the stellate ganglion (cervicothoracic) is formed from the fusion of the first thoracic ganglion with the inferior cervical ganglion), four lumbar ganglia, and four or five sacral ganglia. In the area of the coccyx there is a small ganglion impar. The ...
As the Cleveland Clinic explains, because it’s hemorrhagic, it “damages blood vessels and causes bleeding” — often from the eyes, nose, mouth, or vagina. Science Photo Library/Getty.
One possible cause of Harlequin syndrome is a lesion to the preganglionic or postganglionic cervical sympathetic fibers and parasympathetic neurons of the ciliary ganglion. [7] It is also believed that torsion (twisting) of the thoracic spine can cause blockage of the anterior radicular artery leading to Harlequin syndrome. [8]
