The Functional Anatomy of the Foramina of Luschka Revisited

Background: The German Anatomist Hubert Von Luschka first described Foramen of Luschka (FOL) in 1855 as lateral holes in the fourth ventricle. By his discovery, he refuted previous beliefs about the lateral recess as blind ends of the fourth ventricle, proving the continuity of the ventricular system with the central canal of the spinal cord.

Method: We reviewed the existing literature describing the history, pertinent anatomy, and function of FOL in addition to reviewing the original German book written by Luschka.

Results: While reading the available articles and original works regarding FOL, we noticed the developmental phases through which FOL was discovered, tracking the process from Aristotle till Luschka's discovery ([Fig. 1]). We also discussed controversies and opinions about FOL's existence and function.

Conclusion: FOL is halved into two compartments; choroidal and patent. The function of FOL resembles a one-way valve mechanism, and it depends on the patent slit-like part. Luschka had discovered over 20 anatomical structures, including several foramina, confusion in a debate may result from eponyms.
