Summary
Recurrent idiopathic trigeminal neuropathy, a rare sensory disorder, presents with recurring facial numbness and tingling. This study reports two unique cases, highlighting the condition
Area of Science:
- Neurology
- Sensory Neuroscience
Background:
- Idiopathic trigeminal neuropathy (ITN) is a rare neurological disorder affecting trigeminal nerve sensory function.
- ITN typically presents with transient sensory disturbances, with acute and chronic forms previously documented.
Observation:
- This report details two distinct cases of recurrent idiopathic trigeminal sensory neuropathy.
- Patients experienced sensory alterations primarily in the tongue and lips, spreading to the face, without pain or muscle weakness.
Findings:
- One patient had complete recovery followed by recurrence after 3 years, affecting the entire trigeminal nerve territory.
- The second patient experienced annual winter recurrences for over a decade, impacting the second and third trigeminal nerve branches.
Implications:
- These cases suggest that recurrent idiopathic trigeminal sensory neuropathy is a distinct clinical entity.
- Further research is warranted to understand the pathophysiology and long-term management of recurrent ITN.
