Summary
This cadaveric study compares microsurgical and endoscopic anatomy of the cavernous sinus (CS). Both approaches are feasible in cadavers, aiding neurosurgeons in treating CS lesions.
Area of Science:
- Neurosurgery
- Anatomy
- Surgical Techniques
Background:
- The cavernous sinus (CS) presents significant anatomical challenges for neurosurgeons.
- Existing cadaveric studies often focus on either microsurgical or endoscopic approaches, but rarely compare them side-by-side.
Purpose of the Study:
- To conduct a comparative side-by-side analysis of the microsurgical and endoscopic anatomy of the cavernous sinus (CS).
- To provide insights that can enhance the efficiency of neurosurgical management of CS lesions.
Main Methods:
- Dissection of sixteen fresh cadaveric heads.
- Simultaneous transcranial microsurgical and endoscopic dissections were performed in four heads.
- Sequential dissection and anatomical study of the CS and related structures.
Main Results:
- The study successfully dissected and analyzed the microsurgical and endoscopic anatomy of the CS and associated structures in all specimens.
- Both microscopic and endoscopic exposure of the CS were found to be relatively straightforward in a cadaveric setting.
Conclusions:
- While cadaveric dissection facilitates both microsurgical and endoscopic exposure of the CS, surgical application requires considerable skill.
- The choice between transcranial microsurgery, endonasal endoscopy, or a combined approach depends on the specific pathology and its extent.
