摘要
目的对复发性第Ⅲ支三叉神经痛患者行下齿槽神经管开窗并行下齿槽神经全切除、神经管内置入无机活性诱导元素,利用其成骨特性以治疗复发性三叉神经痛的疗效分析。方法选择下牙槽神经撕脱术后复发病例18例,用球形磨钻磨除下颌第一前磨牙至下颌角下牙槽神经管周围骨质,形成直径约2cm的长条形骨窗,完整切除下齿槽神经,磨钻选磨,置入无机活性诱导材料。对患者术后随访至少2年,并对本手术方法治疗下齿槽神经痛的疗效进行评价。结果患者切口均Ⅰ期愈合,术后未出现水肿、感染等并发症。6例患者术后7 d内有余痛不止,1周后疼痛基本消失,X线连续观察2年下齿槽神经管成骨效果良好。结论本手术方法可以有效治疗复发性第Ⅲ支三叉神经痛,副作用是下齿槽神经切断造成的局部麻木。
Objective To analyze the therapeutic effects of inorganic active induced element through its character of bone formation in treating palindromic trigeminal neuralgia Ⅲ by artifistulation of inferior alveolar neural tube, total resection of inferior alveolar nerve and inserting inorganic activity element graft. Methods We selected 18 palindromic cases after inferior alveolar nerve avulsion, stripped inferior alveolar neural tube （from mandibular first premolar to angle of mandible） with pot mill to form a long strip of bony window about 2 cm diameter and selectively grinded, totally resected inferior alveolar nerve, and then inserted inorganic active induced element. We followed these patients for at least 2 years, and then evaluated the therapeutic effects of this method. Results Incision was primarily healing, and no complication such as dropsy and inflammation appeared. 6 cases remained painful within 7 days and the pain nearly disappeard 1 week later. Radioactive ray showed bone formation was well in inferior alveolar neural tube. Conclusion This method has been proved to treat palindromic trigeminal neuralgia Ⅲ effectively. However, monoanesthesia is the main side effect.
