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.
