Trigeminal Neuralgia: Rapid Evidence Review

Area of Science:

• Neurology
• Pain Medicine
• Neurosurgery

Background:

• Trigeminal neuralgia (TN) is a chronic neuropathic pain condition causing severe, lancinating facial pain.
• Pathophysiology involves nerve root compression, demyelination, and neurovascular compromise.
• Onset typically occurs between 50-60 years, increasing with age.

Purpose of the Study:

• To summarize the clinical presentation, diagnosis, and management of trigeminal neuralgia.
• To highlight diagnostic criteria and recommended imaging.
• To review current treatment strategies, including pharmacotherapy and surgical options.

Main Methods:

• Diagnosis relies on International Headache Society criteria for classic, secondary, and idiopathic TN.
• Brain MRI with contrast is recommended for differential diagnosis and surgical candidacy.
• Treatment follows tailored approaches based on TN type and etiology.

Main Results:

• Carbamazepine is the first-line pharmacotherapy, achieving initial symptom control in 75% of patients.
• Adjunctive drugs and surgical evaluation are considered for refractory cases or adverse effects.
• Microvascular decompression demonstrates superior efficacy compared to other surgical interventions.

Conclusions:

• Effective management of trigeminal neuralgia requires accurate diagnosis and tailored treatment strategies.
• Pharmacotherapy provides initial relief for most patients.
• Microvascular decompression is a highly effective surgical option for refractory trigeminal neuralgia.
