Radiofrequency (RF) can be applied to the gasserian
ganglion in two ways: thermal RF and the pulsed RF (PRF) mode.
Diagrammatic representation showing the convergence of three sensory brances of trigeminal nerve into Gasserian
Trigeminal neuralgia which is resistant to medical treatment, may be benefited from percutaneous procedures like glycerol, phenol, alcohol and radiofrequency (RF) rhizolysis that damage the trigeminal nerve or the Gasserian
ganglion so that peripheral stimuli no longer trigger an attack of trigeminal neuralgia13,14.
ganglion of the trigeminal nerve has 3 branches, namely, the ophthalmic and maxillary nerves, and the sensory root of the mandibular nerve.
In December 2016, she underwent a Gasserian
ganglion nerve block at the Department of Anesthesiology of our hospital.
The trigeminal (or semilunar or gasserian
) ganglion is centered along the anterior, inferior and lateral wall of the Meckel's cave, which is essentially a cerebrospinal fluid (CSF) filled space continuous with the subarachnoid space of the basal cisterns through the porus trigeminus (5).
Trigeminal nerve starts at the midlateral surface of the pons, and its sensory ganglion (gasserian
ganglion) resides in Meckel's cave in the floor of the middle cranial fossa.
As a minority of cases of classical trigeminal neuralgia are not caused by vascular compression and appear to be idiopathic, it is possible that disordered physiological, anatomical, genetic, toxic, or degenerative factors may precipitate the generation of abnormal discharges by the Gasserian
ganglion, the trigeminal nerve root, or the trigeminal nucleus, causing the neuralgic pain [20, 35].
TGN root involvement in posterior fossa would present with intradural tumors, and the gasserian
ganglion involvement in middle cranial fossa would present with extra dural mass apart from symptoms of continuous facial pain, facial paresthesia, numbness, and so forth.

A pr6ospective study of Gasserian
ganglion pulsed radiofrequency combined with continuous radiofrequency for the treatment of trigeminal neuralgia.
The foramen ovale is a surgically important aperture in that it lies just distal to the gasserian
(Meckel's) cave which houses the trigeminal ganglion.
