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.
