Supracerebellar Infratentorial Approach, Indications, and Technical Pitfalls.

Area of Science:

• Neurosurgery
• Skull Base Surgery

Background:

• The posterior tentorial incisura is a critical surgical area for pineal gland, midbrain, and cerebellar pathologies.
• Traditional supratentorial approaches present challenges in accessing this central brain region.

Purpose of the Study:

• To highlight the advantages of the infratentorial supracerebellar approach for posterior tentorial incisura lesions.
• To discuss the evolution and current safety of this surgical corridor.

Main Methods:

• Review of the infratentorial supracerebellar surgical corridor.
• Comparison with alternative supratentorial and infratentorial routes.
• Discussion of historical complications and modern solutions.

Main Results:

• The infratentorial supracerebellar route provides a direct and shortest path to the posterior tentorial incisura.
• Historical complications included cerebellar infarction, air embolism, and neural damage.
• Contemporary neurosurgical advancements have mitigated these risks.

Conclusions:

• The infratentorial supracerebellar approach is a valuable and safe option for accessing lesions in the posterior tentorial incisura.
• Modern surgical techniques and anesthesiology have significantly improved outcomes.
