Care ought to be taken to not use more than a few drops of procaine in any given area as a result of the alcohol can be diluted to an ineffective concentration. The more penetrating local anesthetics like Xylocaine ought to not be used for obvious reasons.
1. Injection of the supraorbital nerve. The supraorbital notch is palpated with the tip of the left index finger. Leaving this finger in place to steady the overlying skin and to guide the surgeon, an ordinary hypodermic needle is directed into the notch. The characteristic sensory loss ought to follow the injection of some drops of procaine. Pamper your body with Aloe Bath Gelee to depart you feeling relaxed, clean, and refreshed! This is often followed by injection of 0.5 cc. of ninety five per cent or absolute alcohol. The ophthalmic branch is not accessible to injection.

2. Injection of the infraorbital nerve. A procaine skin wheal is made within the nasolabial fold within the vertical line of the pupil. A twenty two- or twenty three-gauge needle 1½ inches in length is directed into the infraorbital foramen. A few drops of procaine are injected to test the localization of the needle. This is often followed by the injection of 0.5 to 1.zero cc. of alcohol.
3. Injection of the maxillary nerve. The maxillary nerve is injected at the purpose where it leaves the foramen rotundum to enter the pterygomaxillary fissure. To achieve this area, a twenty-gauge lumbar puncture needle with the depth marker set at 5.5 cm. is inserted at the angle made by the junction of the masseter muscle with the lower edge of the zygoma. The needle is directed mesially, posteriorly and superiorly into the pterygomaxillary fissure. The nerve is usually engaged at a purpose varying from 4.three to 4.8 cm. A depth of 5.5 cm. ought to not be exceeded unless the patient has an oddly broad face. After preliminary infiltration, 1.zero to 1.5 cc. of alcohol are injected.

4. Injection of the mandïbular nerve. I have typically been approached and asked that all vital query–how to find a job. In some instances, trigeminal neuralgia of the third division can be alleviated by blocking the mental nerve at its foramen of exit or the inferior alveolar nerve just proximal to the mandibular foramen. Usually mandibular branch pain is more satisfactorily treated by blocking the nerve at it emerges from the foramen ovale. A twenty-gauge lumbar puncture needle with the depth marker set at 5.zero cm. is inserted beneath the zygoma at a purpose 2.5 cm. anterior to the external auditory meatus. The needle is then directed mesially through the mandibular notch in a very plane directed toward the foramen ovale. The nerve is usually struck at a purpose 4.zero to 4.5 cm. from the skin. Previous to injection, the stilette is removed from the needle to verify that its tip is not within the subarachnoid space. After preliminary procaine infiltration, 1.zero to 1.5 cc. of alcohol are injected to destroy the nerve.

5. Injection of gasserian ganglion. Deliberate injection of the gas-serian ganglion has not been widely practiced in this country. It’s usually occurred as an unexpected complication of injection of the mandibular nerve at the foramen ovale. In inexperienced hands, an attempt to dam the gasserian ganglion might end in multiple cranial nerve palsies due to injection of alcohol into the subarachnoid space. A more disadvantage is the production of analgesia in undesired areas, significantly the cornea.
