Clinical feature and surgical strategy for sellar region meningioma

Abstract:

Objective：To summarize and to explore the clinical features and surgical strategies for sellar region meningioma. Methods： Clinical data of 49 cases of sellar region meningioma treated by surgery in our hospital were analyzed retrospectively. Clinical features of suprasellar and parasellar meningiomas were analyzed；differences between unilateral subfrontal approach and pterional approach were compared and surgical strategies of sellar region meningioma were summarized. Results：Vision and visual field damage and pitu－itary compress were more common in suprasellar meningioma. Among 49 cases of sellar region meningioma，total removal was made in 33 cases（Simpson Ⅰ，Ⅱ）while subtotal removal in 14 cases（Simpson Ⅲ）and partial removal in 2 cases（Simpson Ⅳ）. Total removal rate was 67.3%. There was no difference in intraoperative blood loss，operative time and postoperative hospital stay between two main different types of surgical approach（unilateral frontal approach and pterional approach）（P>0.05）. Conclusion：Suprasellar and parasellar meningiomas have different clinical features；vision and visual field damage and compresssion of pituitary is more common in the former. On the basis of preserving nerve function and quality of life，maximum resection is the main direction. Unilateral sub－frontal approach and pterional approach both achieve good exposure of sellar region. No difference in intraoperative blood loss，oper－ative time and postoperative hospital stay are observed.
