• Resumen

  • According to the International Classification of Orofacial Pain (ICOP), secondary trigeminal neuralgia can result from various conditions such as tumors in the cerebellopontine angle, arteriovenous malformation, and multiple sclerosis. This case report describes a 41-year-old woman with trigeminal neuralgia caused by narrowing of the cerebellopontine cistern due to an enlarged suprameatal tubercle. Carbamazepine treatment was initially effective, but became inadequate within a few months. Magnetic resonance imaging revealed compression of the trigeminal nerve by the superior cerebellar artery and an enlarged suprameatal tubercle. Microvascular decompression surgery was done to alleviate the neurovascular compression. Dentists should be aware of such anatomical factors contributing to trigeminal neuralgia, particularly in younger patients.
