摘要
Objective: To present a large series of surgically treated tuberculum sellae meningiomas with particular regard to involvement of the optic canal and visual outcome. Methods: A retrospective analysis was done on 53 patients (40 female)- with meningiomas originating from the tuberculum sellae who underwent surgery b etween 1991 and 2002. The standard surgical approach consisted of pterional cran iotomy. Sixteen meningiomas extended posteriorly onto the diaphragma sella, 29 a nteriorly to the planum sphenoidale, and 19 to the anterior clinoid process. Thi rty seven tumours involved the optic canal, three bilaterally. Follow up ranged from 6 to 108 months (mean 29.9 months). Results: Total macroscopic resection wa s achieved in 48 patients. Median tumour size was 2.6 cm. Postoperatively, visua l acuity improved in 20 patients and deteriorated in seven. Preoperative and pos toperative visual acuity wors ened with increasing duration of preoperative symptoms and with increasing ag e. Extension into the intraconal space was a negative predictor. However, tumour size did not influence visual acuity. Recurrence occurred in two cases (21 and 69 months postoperatively). Two patients died from causes unrelated to the tumou r. Conclusions: In the majority of patients with tuberculum sellae meningiomas, total resection may be achieved through a pterional approach with minimal compli cations.
