Background: Only 2%-5% of all patients with trigeminal neuralgia (TN) have localized disease to the first branch (V1). In this report, we describe the management of five cases of pure V1 territory TN.

Methods: The series included three men and two women with a mean age of 63 years. The affected side was the right side in four cases and the left side in one case. All cases presented with typical TN manifestations. Preoperative three-dimensional magnetic resonance cisternogram/angiogram fusion images were obtained to evaluate the anatomical relationship between the trigeminal nerve and the responsible vessel. Microvascular decompression (MVD) was performed using the retrosigmoid approach.

Results: The postoperative course was excellent in all patients. No obvious postoperative complications were observed. The surgical findings were consistent with the preoperative imaging findings. Vessel compression was identified primarily from the supero-medial side of the nerve, and the most compressed site tended to be on the caudal side on the supero-medial plane in four cases.

Conclusions: The direction of compression on the nerve of the pure V1 TN was assessed. MVD is an effective treatment for pure V1 TN.
