To discuss an effective surgical treatment of a subtype of trigeminal neuralgia with descending palatine neuralgia of the maxillary division.
Nine patients, who suffered from trigeminal neuralgia with descending palatine neuralgia of the maxillary division, received neurotomy and avulsion of the descending palatine nerve in the pterygopalatine fossa via the greater palatine foramen-pterygopalatine canal approach. Seven of the patients had a recurrence of descending palatine neuralgia after they received treatment of maxillary neuralgia with neurotomy and avulsion of the infraorbital nerve; two patients were diagnosed with descending palatine neuralgia of the maxillary division in our department. Postoperative follow-up was conducted.
Pain in the palate disappeared; all patients felt numb and paresthetic in the area innervated by the trigeminal nerve, with no pain. During the 3-36 months of follow-up, no recurrence occurred.
Descending palatine neurotomy in the pterygopalatine fossa via the greater palatine foramen-pterygopalatine canal approach is a simple, safe and effective way to treat a subtype of trigeminal neuralgia--descending palatine neuralgia.
探讨一种治疗伴有上颌支腭降神经痛的三叉神经痛亚型的有效手术方法。
9例伴有上颌支腭降神经痛的三叉神经痛患者，经腭大孔-翼腭管入路在翼腭窝行腭降神经切断及撕脱术。其中7例患者在接受眶下神经切断及撕脱术治疗上颌神经痛后出现腭降神经痛复发；2例患者在我科被诊断为上颌支腭降神经痛。术后进行随访。
腭部疼痛消失；所有患者在三叉神经支配区域均有麻木和感觉异常，但无疼痛。在3至36个月的随访期间，无复发。
经腭大孔-翼腭管入路在翼腭窝行腭降神经切断术是治疗三叉神经痛亚型——腭降神经痛的一种简单、安全且有效的方法。
