This mini-invasive treatment, practiced at the Ugo Delfino Medical Studio, is performed on a sedated patient with targeted fluoroscopy. Special radiological imaging makes it easy to view the foramen ovale and reach the Gasserian ganglion. Chemical lesions with ethanol creates a minimal wound which will last 20-30 years, and which does not touch any part of the brain. This kind of action damages the pain-sensory nerves yet saving the other, more resistant nervous structures. In this way, the sensitivity of the face is preserved. This technique, unlike any other, has been employed extensively since 1978 and is practical for all ages with complete safety.
