The orbitozygomatic infratemporal approach: a new surgical technique

Area of Science:

• Neurosurgery
• Surgical Neurology
• Skull Base Surgery

Background:

• Lesions in the parasellar and interpeduncular regions present significant surgical challenges due to difficult access.
• Conditions include medial-third sphenoid wing meningiomas, petroclival meningiomas, trigeminal neurinomas, and basilar tip aneurysms.

Purpose of the Study:

• To introduce and evaluate a new surgical technique, the orbitozygomatic infratemporal approach.
• To minimize brain retraction and optimize surgical exposure for lesions in difficult-to-reach cranial base areas.

Main Methods:

• The study details the operative technique of the orbitozygomatic infratemporal approach.
• The approach was applied to sixteen patients with parasellar tumors and ten patients with basilar tip aneurysms.

Main Results:

• The orbitozygomatic infratemporal approach facilitated radical procedures with excellent results.
• The technique allowed for minimized brain retraction and effective surgical manipulation.

Conclusions:

• The orbitozygomatic infratemporal approach is a valuable technique for managing complex lesions in the parasellar and interpeduncular regions.
• This approach provides excellent exposure and safe manipulation, leading to successful surgical outcomes.
