OBJECTIVE: To estimate the relative risk of meningitis after repair of spontaneous lateral skull base cerebrospinal fluid (CSF) leaks through meta-analysis of published studies.
DATABASES REVIEWED: PubMed, Medline, Embase, Cochrane, SCI-EXPANDED, ESCI, Epistemonikos, and WHO Global Index Medicus were queried for terms including and related to meningitis, CSF leak, surgery, and spontaneous from inception to April 02, 2024.
METHODS: Prospective and retrospective studies in any language reporting either preoperative or postoperative rates of meningitis in adults with spontaneous lateral skull base CSF leaks were included. Two reviewers independently screened 2,564 studies and extracted data and evaluated risk of bias in 57 studies that met inclusion criteria. A random effects generalized linear mixed model was used to pool and compare logit transformed risk of meningitis before and after repair.
RESULTS: Of 1,310 patients who met inclusion criteria, 1,239 underwent CSF leak repair. Fifty-two studies reported rates of preoperative meningitis, and 27 studies reported rates of postoperative meningitis. Twenty-two studies with a total of 511 patients reported both rates. The average follow-up period of 17 studies reporting duration of follow-up was 23.1 months. The preoperative pooled risk of meningitis was 0.16 (95% CI: 0.13-0.25, I 2 = 40.57%). The postoperative pooled risk was considerably lower at 0.01 (95% CI: 0.01-0.14, I 2 = 4.16%). With substantial heterogeneity (I 2 = 62.94%), we observed a relative risk of meningitis after repair of 0.02 (95% CI: 0.00-0.79, p = 0.04).
CONCLUSION: Surgical repair of spontaneous lateral skull base CSF leaks may significantly reduce the risk of adult meningitis.
