Vertically Crowded Small Posterior Fossa Is a Possible Cause of Trigeminal Neuralgia in Young Adults: Operative Nuances of Microvascular Decompression Based on Associated Morphological Features

Key Points

Investigate the role of anatomical features in trigeminal neuralgia among young adults.
Examined cases of young adults with trigeminal neuralgia during microvascular decompression.
Focused on anatomical relationships between blood vessels and the trigeminal nerve.
Considered surgical techniques to navigate narrow operative fields.
Identified vertically crowded small posterior fossa as a contributing factor to trigeminal neuralgia.
Highlighted effective microvascular decompression strategies to alleviate symptoms.
Improved surgical outcomes were reported following the procedure.

Abstract

Vertically crowded small posterior fossa leading to artery and/or vein contact with the trigeminal nerve is the possible cause of TN in young adult patients. MVD with opening of the horizontal fissure to widen the narrow operative field ensures good surgical outcomes for young adult patients.
