Anterior selective amygdalohippocampectomy: technical description and microsurgical anatomy

Area of Science:

• Neurosurgery
• Surgical Anatomy
• Minimally Invasive Techniques

Background:

• Selective amygdalohippocampectomy (AH) is a crucial procedure for treating mesial temporal lobe epilepsy.
• Traditional approaches can be invasive, risking damage to critical neural pathways.

Observation:

• A minisupraorbital craniotomy was utilized for anterior selective AH in cadaveric specimens.
• Anatomical assessment and image-guided navigation confirmed the feasibility of accessing and resecting the amygdala and hippocampus.
• Key surgical measurements were obtained, including distances to the temporal horn and cerebral peduncles.

Findings:

• The anterior minisupraorbital route successfully facilitated the removal of the amygdala and hippocampus.
• This approach demonstrated a favorable safety profile, minimizing disruption to the optic pathway, temporal stem, and lateral temporal neocortex.
• Clinical application confirmed satisfactory resection of target structures.

Implications:

• The minisupraorbital approach offers a less invasive and destructive alternative for selective AH.
• This technique holds potential for improved patient outcomes in mesial temporal lobe epilepsy surgery.
• Further research can explore the long-term efficacy and broader clinical application of this surgical method.
