Arterial neurovascular compression is hypothesised to be the main cause of primary trigeminal neuralgia. Although it is the most common cause, other pathologies, such as tumours in the cerebellopontine angle, can cause trigeminal pain. We report a case of a 44-year-old female patient with right trigeminal neuralgia without satisfactory response to medical treatment. Cerebral MRI showed no structural injuries. During microvascular decompression of the trigeminal nerve, endostosis of the internal aspect of the petrous bone was found to compress the trigeminal nerve. The pain disappeared completely in the early postsurgical period, after the complete drilling of the endostosis and microvascular decompression. The patient remains asymptomatic one year later. Endostosis of the petrous bone is a rare cause of trigeminal neuralgia. A proper review of preoperative studies would enable the definitive surgical approach to be optimised.
动脉神经血管压迫被认为是原发性三叉神经痛的主要原因。虽然它是最常见的病因，但其他病变，如桥小脑角肿瘤，也可导致三叉神经痛。我们报告一例44岁女性患者，患有右三叉神经痛，药物治疗效果不佳。脑部MRI未显示结构损伤。在三叉神经微血管减压术中，发现岩骨内侧面骨化压迫三叉神经。在完全钻除骨化并进行微血管减压术后早期，疼痛完全消失。一年后患者仍无症状。岩骨内侧面骨化是三叉神经痛的罕见病因。对术前检查进行适当评估有助于优化确定性手术方法。
