Prevalence of trigeminal neuralgia in Jincheng, China

This study provides the first epidemiological data on TN prevalence in Jincheng City, China. The estimated prevalence aligns with findings from several international studies, though regional differences remain. The female predominance in TN cases and the higher incidence of right-sided involvement are consistent with global trends. Further studies with larger sample sizes and updated diagnostic criteria are needed to explore potential regional and genetic factors influencing TN prevalence and to assess the long-term impact of TN on public health in China.
