Abstract
The aim of this article is to investigate the related factors affecting the recurrence
of microvascular decompression (MVD) after trigeminal neuralgia. We selected 400 cases
of patients who met the diagnostic criteria of primary trigeminal neuralgia. The recurrence
rate of patients and their statistical data related factors such as age, gender, disease
duration, pain branches, vascular compression, patients, and complications (urban
and rural), were collected. Of the 400 cases, 36 had recurrence after 2 years. In
female group, the recurrence rate was (9.4%) higher than the recurrence rate in male
group (8%); no recurrence rate of vascular compression group (40%) was higher than
that of vascular compression group recurrence rate (8.6%); the recurrence rate of
each branch in pain group from high to low was V2–3 (13.4%), V2 (12.5%), V1 (9.1%), V3 (7.5%), V1–2-3 (4.4%), V1–2 (4.3%), V1–3 (0%); and the difference was statistically significant (p < 0.05).Gender of the patient, the presence of vascular pressure, and the branch
of pain could significantly affect the postoperative recurrence rate of trigeminal
neuralgia in patients treated with simple MVD (p < 0.05).
