삼차신경통의 진단과 치료 = Diagnosis and treatment of trigeminal neuralgia

다국어 초록 (Multilingual Abstract)

Background: Trigeminal neuralgia is a sudden and painful facial condition that is triggered by activities of daily living. The pain is debilitating and patients are often unable to perform routine daily tasks such as washing their face, shaving, and brushing their teeth, which in turn has an impact on their social life and mental well-being as they are often anxious and fearful of not knowing when the pain may occur.
Current Concepts: Treatment for trigeminal neuralgia involves local nerve destruction surgeries, including neuro blocking, percutaneous ethanol injection therapy, percutaneous radio-frequency rhizotomy, and gamma knife surgery. Although these types of surgeries reduce pain, the side effects are unpleasant and include decreased facial sensation, which originates from the damage to the trigeminal nerve. Furthermore, these surgeries provide insufficient long-term outcomes and symptoms often recur. Microvascular decompression is a radical surgical approach that separates the blood vessels that cause pain from the nerves. In a large-scale study, microvascular decompression significantly reduced the pain in 80.96% of the patients who underwent initial treatment. Of these, 85% experienced significant pain reduction 38 months post-surgery, and 72.85% reported that they were able to manage their pain 5 years post-surgery. Currently, microvascular decompression is the most appropriate surgical approach to control pain in patients with trigeminal neuralgia, as it exhibits the highest rate of pain control and lowest rate of recurrence.
Discussion and Conclusion: The accurate diagnosis of trigeminal neuralgia, through clinical symptoms and imaging, is important to obtain good treatment outcomes. Microvascular decompression should be considered when a patient responds poorly to initial treatment approaches, cannot receive surgical treatment due to side effects, or experiences pain recurrence following local nerve destruction.
