Trigeminal neuralgia (TN) is a chronic condition that is typically caused by a blood vessel exerting pressure on the V cranial nerve at the root entry zone. The gold standard for TN treatment is microvascular decompression (MVD). This illustrative case shows an advanced surgical technique that combines the use of an exoscope and endoscope to treat TN with an innovative addition of intraoperative indocyanine green (ICG) control that can improve arterial and venous compression identification. The use of exoscopes and endoscopes, offering 360° root assessment, represents a significant evolution in surgical approaches. Enhanced visualization with ICG aided in identifying complex neurovascular conflicts, improving decompression accuracy. The use of both exoscope and endoscope, offering a 360° root assessment, represents a significant evolution in the microsurgical approach of TN. The additional use of ICG monitoring in a dynamic mode may be useful in identifying the complex arteriovenous form of neurovascular conflict. The endoscopically assisted exoscopic surgery with the intraoperative use of ICG for MVD of the trigeminal nerve can improve the identification of complex impingements underlining its effectiveness and potential in neurosurgical practice.
