The Current State of Research on Postoperative Cerebellar Mutism Syndrome: A Bibliometric Analysis

This study presents a bibliometric analysis of cerebellar mutism syndrome (CMS), a severe postoperative complication in pediatric patients with posterior fossa tumors. A total of 445 publications were included in the study from a Web of Science query done on October 18, 2024. Publication output has steadily increased with research concentrated in developed nations, particularly the United States, which leads in publications and citations. Since 2020, developing nations in Africa, Latin America, and Asia have started to contribute more. The United Kingdom leads in collaboration. St Jude Children's Research Hospital is the top contributor. Regional collaboration is notable in Nordic institutions, Benelux institutions, and Italian institutions. International collaborations with institutions from developing nations, although still low, are increasing. Child's Nervous System is the leading journal. Recent keyword trends focus on surgical techniques, imaging modalities, and long-term outcomes. This bibliometric analysis provides an overview of CMS research, identifying key trends, collaborations, and gaps in the field.
