颅底病变手术入路方法选择的探讨

SELECTION OF OPERATIVE APPROACHES FOR CRANIAL BASE LESIONS

1992～1996年间治疗10例颅底部肿瘤和齿状突骨折。其中斜坡肿瘤3例。齿状突骨折7例。10例均经CT或MRI、DSA检查确诊.经口咽入路或前颅凹底入路两种方式将肿瘤切除。术后患者临床症状都得到了良好改善,无一例死亡。作者认为,斜坡肿瘤和齿状突骨折经前颅凹底或口咽显微外科治疗是一种安全有效的方式。

The authors reported 3 cases of clival tumors and 7 cases of odontoid process fractures of the axis, they were operated via the oral - pharyngeal or the anterior cranial fossa base approach. In one of the 3 cases of the clival tumor, the tumor invading the sphemoid sinus and the ethmoid sinus and was resected through the anterior cranial fossa approach. The remain 2 cases were operated via the transoral pharyngeal approach. All of the odontoid process fractures of axis were treated through transoral - pharyngeal approach. In this series, excellant outcomes were achieved without death or severe complication. It is concluded that the microsurgical operation via the oral - pharyngeal or the anterior cranial fossa base approach is a safe, effective method to treat the clival trmors and odontoid process fractures of axis.
