Vascular decompression with videoendoscopy as a treatment for glossopharyngeal nerve neuralgia: clinical case and literature review
The objective is to demonstrate the effectiveness of the vascular decompression with videoendoscopy in the treatment of classical glossopharyngeal nerve neuralgia by a clinical case and to summarize the literature data on this subject. Clinical case. In February 2020, a 56-year-old patient with a clinical picture of glossopharyngeal nerve neuralgia was admitted to the Research Clinical Center of Specialized Medical Care and Medical Technologies. The pain syndrome bothered about 3 years, constantly took carbamazepine at a dose of 1200 mg per day, amitriptyline 75 mg per day, clonazepam 2 mg per day without effect. After further examination and differential diagnosis of causal neuralgia of the glossopharyngeal nerve, a neurovascular conflict appeared between the glossopharyngeal nerve, the posterior inferior cerebellar and vertebral arteries. A good postoperative clinical result was obtained. An analysis of the available scientific literature on this problem is carried out.Results. After performing vascular decompression of the root of the glossopharyngeal and vagus nerves, pain completely regressed (BNI - I, VAS - 0). 6 months after surgery, there is no pain, the patient does not receive drug therapy. In the course of the analysis of available literature, the effectiveness of vascular decompression in the treatment of patients with classical neuralgia reaches 98 %.Conclusion. Given the low incidence of glossopharyngeal neuralgia, the correct diagnosis and the choice of an appropriate treatment method determine the outcome of the disease. The performed operation in the volume of vascular decompression of the glossopharyngeal nerve root with the use of videoendoscopy allowed to completely stop the pain syndrome.
