Summary
Young onset trigeminal neuralgia (TN) in patients under 30 is primarily caused by neurovascular compression, most often the superior cerebellar artery (SCA). Microvascular decompression (MVD) offers a safe and effective treatment, providing significant pain relief.
Area of Science:
- Neurosurgery
- Neurology
Background:
- Trigeminal neuralgia (TN) typically affects older adults.
- Younger patients (<30 years) with primary TN present unique diagnostic and management challenges.
Purpose of the Study:
- To investigate the underlying causes of primary young onset trigeminal neuralgia (TN).
- To evaluate the clinical outcomes and efficacy of microvascular decompression (MVD) in this patient group.
Main Methods:
- Retrospective analysis of 19 patients under 30 with primary TN who underwent MVD.
- Detailed review of clinical characteristics, surgical findings, and postoperative outcomes.
- Assessment of complications and long-term pain recurrence.
Main Results:
- Neurovascular compression was identified in 17 patients (89.5%), with the superior cerebellar artery (SCA) being the most frequent cause (14 cases).
- 18 out of 19 patients (94.7%) experienced immediate pain relief post-MVD.
- One patient had a relapse 45 months after surgery; complications were mild (facial numbness, hearing impairment).
Conclusions:
- Neurovascular compression, particularly by the SCA, is the primary etiology for young onset primary TN.
- Microvascular decompression (MVD) demonstrates high safety and efficacy for treating young patients with primary TN.
