Considering the abundance of articles addressing Moyamoya disease, a detailed analysis concerning the publication trends is of paramount importance. The aim of the study is to report the current knowledge of the top-100 most cited articles on Moyamoya disease in the literature. METHODS: A non-time restricted keyword-based search was performed in June 2020 using the Scopus database.
