Summary
This study details the microsurgical anatomy of the cavernous sinus in Turkish adults. Key findings include abducent nerve rootlet variations and venous space dominance, crucial for neurosurgical procedures.
Area of Science:
- Neurosurgery
- Anatomy
Background:
- The cavernous sinus is a critical anatomical region for neurosurgical interventions.
- Understanding its detailed microsurgical anatomy and morphometry is essential for surgical safety and precision.
Purpose of the Study:
- To investigate the microsurgical anatomy of the cavernous sinus in Turkish adult cadavers.
- To provide morphometric data on topographic aspects relevant to neurosurgery.
Main Methods:
- Dissection of 108 cavernous sinus specimens from 54 Turkish adult cadaveric heads.
- Detailed examination of the abducent nerve, venous spaces, and arterial origins within the cavernous sinus.
Main Results:
- The abducent nerve exhibited variations in rootlet number (1-4), with one rootlet being most common (78%).
- The anterior inferior venous space was dominant in 58% of specimens.
- The artery of the inferior cavernous sinus and dorsal meningeal artery frequently originated from the internal carotid artery (ICA).
Conclusions:
- The study provides valuable morphometric data on the cavernous sinus anatomy.
- These findings enhance the understanding of regional variations, aiding neurosurgeons in complex procedures.
