Trigeminal neuralgia caused by compression of the trigeminal nerve between the vertebral artery and Meckel’s cave meningioma extending to the posterior fossa successfully treated with the endoscopic-assisted anterior petrosal approach

Surgical resection of tumors near the trigeminal nerve causing TN must carefully examine the trigeminal nerve from the REZ to Meckel's cave to identify any coexistent vascular compression, which may be difficult using only a microscope due to significant displacement of the trigeminal nerve. In such cases, the use of an endoscope is effective to inspect the entire trigeminal nerve directly.
