ObjectiveCraniovertebral junction (CVJ) meningiomas are one of the most surgically complex conditions in neuro-oncologic surgery. The aim of this work is to correlate our data with clinical outcome to outline factors leading to a worse functional prognosis.MethodsWe analyzed sex, age, clinical presentation, topography, surgical approach, Simpson grade resection, postoperative lower cranial nerve deficits, consistency, histology, site of origin, presence of a capsule, and radiologic and clinical follow-up at 1, 6, and 12 months of 61 patients affected by CVJ meningiomas, operated on in our institution from 1992 to 2014.Results78.7% of patients were women (mean age, 52.85 years); the onset symptom was pain in 65.5% of cases. The mean preoperative Nurick grade of the sample was 3.78; the most frequent histologic type was endotheliomatous (42.8%). We treated 22 patients with a posterior median approach (5 with lateral and 17 with posterolateral axial topography); in 39 cases (30 anterolateral and 9 anterior) we performed a posterolateral approach. Gross total removal was achieved in 85.2% of cases. We recorded a final follow-up step overall neurologic improvement in the cohort (average preoperative Nurick grade, 3.81, and at 12 months, 2.13). Twenty-nine patients presented with lower cranial nerve deficit (permanent or transient) and no statistically significant association was found between surgical approach and temporary or permanent postoperative complications.ConclusionsWe selected, in our experience, some predictors of worse outcome: preoperative sphincter impairment, absence of a capsule, cranial site of origin, a poor preoperative functional status, and firm consistency of the tumor.Copyright © 2017 Elsevier Inc.
