三叉神经鞘瘤的诊断与治疗

Diagnosis and Treatment of Trigeminal Neuroma

本文针对我科近１１年收治的三叉神经鞘瘤的诊断与治疗结合文献进行了回顾性析和讨论。该１９例病人全部在术中明视肿瘤生长在麦氏囊或三叉神经主干，多为感觉根。临床表现为：①无论何型三叉神经鞘瘤均有不同程度的持续性患侧面部感觉异常。②少有典型的三叉神经痛之表现。③ＢＡＥＰ各波均可引出，Ⅰ～Ⅴ波间期延长。④ＭＲＩ或头颅薄层颅底ＣＴ扫描多可发现患侧卵圆孔扩大。治疗主要是手术切除。

Retrospective analysis and discussion combined with relative literature of 19 cases of trigeminal neuroma treated in our department during the fat eleven years are carried out in this article. All of 'the tumors were located in Meckel's sac or the main trunk of trigeminal nerve and often Originated from it's sensory root. Their clinical characters as follows: ①No Watter what type of trigeminal neuroma the patients suffered from,they had continuous abnormal sensory in the affected side of the face to some extent. ②Typical trigeminal neuralgia was little. ③All of the waves in BAEP might appear but the interval between I to V waves was longer. ④Enlargment of foramen ovale in the affected side might be found in the film of MRI and thin basicranal CT. Operative removal is the main therapy. We thought that total tesection of tumour in early stage was possible.
