Facial lymphatic malformation: the root cause of trigeminal neuralgia is not its root. Illustrative case

Key Points

• To explore alternative causes of trigeminal neuralgia (TN) that may not relate to the root entry zone compression.
• Illustrative case analysis of trigeminal neuralgia presentation
• Detailed anatomical assessment of the trigeminal nerve
• Discussion of treatment implications based on findings
• Identified a case of TN caused by compression distal to the root entry zone
• Proposed that full anatomical considerations may reveal other compression points
• Challenged the conventional view regarding the exclusivity of root entry zone compression in TN cases
