Risk factors of herpes simplex virus reactivation after surgery for primary trigeminal neuralgia

The objective of this study is to investigate the risk factors of oral or facial herpes simplex virus (HSV-1) infection after primary trigeminal neuralgia (PTN). The clinical data of 33 PTN patients admitted by the same surgeon in the neurosurgery were retrospectively analyzed. Among the 33 patients, 26 patients underwent microvascular decompression (MVD), 6 patients who have not been found the clear offending vessels during the operation underwent partial sensory rhizotomy (PSR), and only one underwent adhesive band separation. Thirteen patients with postoperative oral and facial HSV-1 infection were selected as the herpes group, and the remaining 20 patients without postoperative oral and facial HSV-1 infection were selected as the non-herpes group. The differences between the two groups were compared by statistical analysis of factors such as gender, age, operation mode, operation time, and serum HSV-1 antibody titer value before surgery. Compared with the non-herpes group, there were no statistically significant differences in sex ratio (P = 0.930), age composition (P = 0.261), or disease profile (P = 0.226). Twenty-six patients underwent MVD operation, eight of whom were infected, and the difference between the two groups was statistically significant (P = 0.029). The operation time of the herpes group was 10–30 min, which was significantly longer than that of the non-herpes group. The difference in operation time between the two groups was statistical...
