Background:
Skull base meningioma management is complicated by their proximity to intracranial neurovascular structures because complete resection may pose a risk of worsening morbidity.
Objective:
To assess the influence of clinical outcomes and surgical management on patient-perceived quality-of-life outcomes, value, and cost-effectiveness.
Methods:
Patients who underwent resection of a skull base meningioma, had adequate clinical follow-up, and completed EQ-5D-3L questionnaires preoperatively and at 1 mo and 1 yr postoperatively were identified in a retrospective review. Cost data from the Value Driven Outcomes database were analyzed.
Results:
A total of 52 patients (83.0% women, mean age 51.9 yr) were categorized by worsened (n = 7), unchanged (n = 24), or improved (n = 21) EQ-5D-3L index scores at 1-mo follow-up. No difference in subcategory cost contribution or total cost was seen in the 3 groups. Patients with improved scores showed a steady improvement through each follow-up period, whereas those with unchanged or worsened scores did not. Mean quality-adjusted life years (QALYs) and cost per QALY improved for all groups but at a higher rate for patients with better outcomes at 30-d follow-up. Female sex, absence of proptosis, nonfrontotemporal approaches, no optic nerve decompression, and absence of surgical complications demonstrated improved EQ-5D-3L scores at 1-yr follow-up. A mean cost per QALY of $27 731.06 ± 22 050.58 was observed for the whole group and did not significantly differ among patient groups (P = .1).
Conclusion:
Patients undergoing resection of skull base meningiomas and who experience an immediate improvement in EQ-5D are likely to show continued improvement at 1 yr, with improved QALY and reduced cost per QALY.

Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Overview of the Skull
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...
