Key Points

The study aims to review and analyze the anatomy of the mastoid emissary foramen (MEF) to inform surgical strategies for posterior cranial fossa surgery.
Conducted a systematic review and meta-analysis of existing literature
Evaluated the prevalence and morphology of the mastoid emissary foramen
Highlighted the importance of high-resolution imaging techniques
Identified significant variability in the morphology of the mastoid emissary foramen
Emphasized the necessity for tailored preoperative imaging to reduce vascular complications
Suggested that understanding MEF anatomy can improve surgical outcomes in posterior cranial fossa procedures

Abstract

The MEF is a common but highly variable anatomical structure. Awareness of its prevalence and morphology is essential for neurosurgical planning, emphasizing the importance of high-resolution preoperative imaging to minimize vascular complications during posterior cranial fossa approaches.
