Surgical Resection of Amygdala and Uncus.

Area of Science:

• Neurosurgery
• Surgical Techniques
• Neuroanatomy

Background:

• The amygdala and uncus are anatomically adjacent to critical neurovascular structures.
• Resection of these deep-seated brain regions presents significant surgical challenges.

Observation:

• A novel trans-anterior T1 subpial approach was utilized for amygdalar-uncal lesion resection.
• Key anatomical landmarks, including the inferior circular sulcus, endorhinal sulcus, and inferior choroidal point, define the resection plane.
• The technique involves opening the lateral ventricle's inferior horn and performing hippocampectomy.

Findings:

• The described surgical technique allows for safe and complete en bloc removal of amygdalar-uncal lesions.
• Fifteen patients underwent successful resection without intraoperative or postoperative complications.
• Histological specimens were obtained in all cases, confirming complete lesion removal.

Implications:

• This approach offers a reliable method for managing amygdalar-uncal pathologies.
• Precise identification of anatomical boundaries is crucial for maximizing resection extent and minimizing neurological deficits.
• The technique holds promise for improving outcomes in patients requiring amygdalar-uncal resections.
