Resection of Insular Glioma Through the Transfrontal Limiting Sulcus Approach

Area of Science:

• Neurosurgery
• Oncology
• Surgical Neurology

Background:

• Traditional transsylvian and transopercular approaches provide limited exposure for insular tumors.
• Maximal and safe resection of insular gliomas remains a significant surgical challenge.
• A novel surgical approach is presented to improve access and resection of insular gliomas.

Purpose of the Study:

• To evaluate the efficacy of the transfrontal limiting sulcus approach for insular glioma resection.
• To determine if this new approach facilitates maximal and safe tumor removal.
• To assess the impact of the approach on patient outcomes.

Main Methods:

• Surgical techniques using the transfrontal limiting sulcus approach for insular gliomas were reported.
• The study analyzed 69 cases of insular gliomas resected via this novel approach.
• Extent of resection and postoperative neurological status were key evaluation metrics.

Main Results:

• The approach was applied to various insular gliomas, including giant tumors (59.42%).
• A high median extent of resection (100%) was achieved, with an overall total resection rate of 79.7%.
• Postoperative outcomes were favorable, with preserved muscle strength and minimal neurological deficits.

Conclusions:

• The transfrontal limiting sulcus approach enables maximal and safe resection of insular gliomas.
• This technique offers a valuable advancement in the surgical management of insular tumors.
• The approach leads to good functional outcomes for patients undergoing glioma resection.
