Glossopharyngeal neuralgia due to vertebrobasilar dolichoectasia is a rare form of neuropathic pain, and presents diagnostic and therapeutic challenges. Clinical presentation: A 67-yearold man presented with severe burning pain in the left oral cavity, with no explanatory findings during dental and ear, nose, and throat evaluations. Temporomandibular joint examination revealed tenderness, and panoramic radiographs showed a noncontributory periapical radiolucency. Magnetic resonance imaging/magnetic resonance angiography revealed abnormally tortuous vertebral arteries compressing the glossopharyngeal nerves and the brainstem. Topical lidocaine reduced pain, confirming glossopharyngeal neuralgia. Carbamazepine was initially ineffective, but at 200 mg pain reduced from 90 to 20 on the visual analog scale. The patient requested and underwent microvascular decompression surgery, which eliminated his pain. Conclusion: When the vertebral artery compresses the glossopharyngeal nerve, the pain is more intense, attributed to its thicker vascular structure. Local anesthetic testing aids in identifying glossopharyngeal neuralgia. Dental practitioners must be skilled in diagnostics and possess anatomical knowledge for accurate evaluation and referral of throat and ear pain. [ABSTRACT FROM AUTHOR] |
