Glossopharyngeal neuralgia rhizotomy

Glossopharyngeal neurotomy is an effective method for the treatment of glossopharyngeal neuralgia. However, after surgery, there are often some discomforts such as pharyngeal numbness and dry mouth. Since the application of microvascular decompression in clinical practice, not only relieves pain, but also preserves the integrity of the nerve, and has many advantages. However, some patients did not find oppressed blood vessels during surgery, and there is still a certain recurrence rate in surgery. Therefore, neurotomy is still one of the effective methods for the treatment of this disease. Treatment of diseases: glossopharyngeal neuralgia Indication Gonadophalangeal nerve rootectomy is applicable to: 1. In the microvascular decompression, no obvious compression vessels are found, and should be replaced by glossopharyngeal nerve root resection. 2. In the microvascular decompression, although the Teflon cotton pad is placed between the blood vessel and the nerve, the patient's pain is still not relieved. 3. After microvascular decompression, the pain does not improve, and this method should be considered. Contraindications 1. Found as a tumor during surgery and can be removed. 2. The patient's body is weak and cannot tolerate the operator. Preoperative preparation 1. Skin preparation, wash the head with soap and water 1 day before the operation, and shave the hair on the morning of the operation. You can also shave your head on the eve of surgery. 2. Fasting the morning of surgery. 3. Oral 0.1g can be given to phenobarbital before surgery to ensure a quiet rest. One hour before the operation, 0.1 g of phenobarbital, 0.4 mg of atropine or 0.3 mg of scopolamine were intramuscularly injected. Surgical procedure Incision, bone window A midline incision or a barbed incision in the posterior cranial fossa. The bone window is about 3 cm in diameter and the lateral edge is up to the sigmoid sinus edge. The dura mater is turned over to the sigmoid sinus. 2. Neurotomy Retract the cerebellar hemisphere, find the glossopharyngeal nerve in the proximal jugular vein hole and cut it with a nerve knife. The adjacent vagus nerve root wire is cut off 1 or 2, and the operation is over. 3. Guan skull The dura mater is tightly sutured, and the muscles, fascia, subcutaneous tissue, and skin are sutured. complication 1. Pharyngeal numbness, dryness, and reduced saliva. 2. The taste of the back of the tongue is weakened. 3. Pain recurrence, more common in those who only cut the glossopharyngeal nerve.
