Prevalence of Trigeminal Neuralgia and Persistent Idiopathic Facial Pain in Afyonkarahisar, Türkiye

Abstract

Background: Population-based studies examining the prevalence of trigeminal neuralgia (TN) and persistent idiopathic facial pain (PIFP) are rare, and data on TN prevalence in Türkiye are very limited, with the prevalence of PIFP being unknown. This study aimed to determine the prevalence of TN and PIFP in Türkiye.

Materials and methods: This population-based epidemiological study has a cross-sectional and descriptive design, and it was carried out in Afyonkarahisar, Türkiye. Participants aged 18 years and older were screened by using a self-assessment form to determine potential patients with TN or PIFP.

Results: A total of 19,237 individuals were included in this study, of which 17,223 responded to the survey questions. TN was diagnosed in 17 individuals, and the prevalence of TN was calculated as 98.5 per 100,000. PIFP was diagnosed in 35 patients, and the prevalence of PIFP was calculated as 202 per 100,000. The mean age of the patients with TN was 54.29 ± 12.98 years, the mean age of patients with PIFP was 49.80 ± 16.10 years, and the female-to-male ratio was 1.13/1 for TN and 2.18/1 for PIFP.

Conclusion: The prevalence of PIFP in Türkiye has been reported for the first time by this study. Additionally, a much higher prevalence of TN was found when compared to previous study.
