Özet

Introduction: We aimed to review the three-dimensional anatomy of the JF and the relationships of its internal structures. Relevant terminology is also discussed in light of the literature review. Materials and Methods: The microsurgical anatomy of the jugular foramen was studied in 12 formalin-preserved cadavers (24 foramina) and 40 dry-skulls (80 foramina). Results: The jugular foramen was exposed by microsurgical dissection with drilling from superior to inferior direction. Observations regarding durai architecture of the jugular foramen and relationships between neurovascular structures passing through the foramen were noted in cadavers. Normal bony construction of the foramen and its anatomical variations were examined in dry-skull specimens. Using photographs and drawings, the anatomy of the jugular foramen is presented, and related terminology is discussed in the light of literature review. Conclusion: Knowledge of the complex and three-dimensional anatomy of the jugular foramen is essential for any surgeon dealing with the jugular foramen lesions. The jugular foramen is a canal. It is better to term it as the jugular canal. Compartmentalization of jugular canal should be termed as the petrosal part, intrajugular part, and sigmoid part, according to the structures that passed through the JF.
