Headache Resolution After Rathke Cleft Cyst Resection: A Meta-Analysis

Objective Rathke cleft cysts (RCC) are benign lesions of the sella that often present with headache. It is not currently well established whether surgical resection of RCC results in resolution of headache. We conducted a meta-analysis to examine the effect of RCC resection on headache resolution. Methods PubMed, EMBASE, and Cochrane databases were searched through June 2017 for articles that evaluated the effect of RCC resection on headache resolution. Pooled effect estimates were calculated using fixed-effects and random-effects models. Results Ten case series with 276 patients were included. Transsphenoidal surgery (TSS) was used to resect RCC in all of the studies. Only 1 patient in 1 study underwent transcranial surgery. Using the fixed effect model, the overall headache resolution prevalence was 71.7% (95% confidence interval [CI] 65.3%, 77.3%) among patients who underwent resection of RCC (I 2  = 76.9%; P -heterogeneity P -interaction P P  = 0.02), percentage of women (slope −0.05; P P P P  = 0.10). None of the above-mentioned results were significant when the random effects model was used. No evidence of publication bias was observed. Conclusion This meta-analysis demonstrates that the resection of RCC in patients presenting with headache is associated with headache resolution.
