Microsurgery for ablating petroclival region meningiomas by infratempo-ral and tentorail-crista petrosa approach
摘要
Abstract
Objective:To explore the clinical effect of ablating petroclival region meningiomas by infratemporal and tentorail-crista petrosa approach in the condition of microsurgery. Methods:The clinical data of 23 patients with petroclival region meningiomas were retrospectively analyzed. The infratemporal and tentorail-crista petrosa approach was chosen. And among these patients,suboccipital ret-rosigmoid approach was associated in 7 cases. Results:The ablating level of tumor is based of Simpson grade:ⅠtoⅡgrade ablated in 12 cases,Ⅲgrade ablated in 3 cases andⅣgrade ablated in 8 cases. After the operation,there is coma in 2 cases,facial nerve function less than Ⅲ grade in 7 cases,optical movement disorder in 11 cases,hearing disturbance in 2 csase,muscle weakness in 3 cases,in-tracranial infeion in 2 cases and one patient died. 15 patients had been follow-up visited in 6-30 months. In these patients,most of the preoperative symptoms and postoperative complications had been improved. In the follow-up phase,the tumor does not reoccur and rem-nant tumor has no advanced in 10 cases. The tumor recurred obviously,and then had been operated in 5 cases. Conclusion:It is an im-portant method that petroclival region meningiomas is operated through infratemporal and tentorail-crista petrosa approach. It has the merit of satisfactory exposure and little surgical trauma. The suboccipital retrosigmoid approach could increase more infratentorail expo-sure range. With regard to the tumor which could not be all ablated more than SimpsonⅢgrade,it should be assisted with gamma knife radial therapy to inhibit the progress of remnant tumor,and then decrease its recurrence rate.关键词
