Are there specific prediction models for trigeminal neuralgia recurrence in 4,291 patients?
A 2025 systematic review and meta-analysis specifically examined prediction models for trigeminal neuralgia recurrence using data from 4,291 patients across 20 studies. This research found that these models show promising ability to distinguish between patients who will and will not experience a return of pain after surgery. However, the study noted that the accuracy numbers might be slightly higher than reality due to inconsistencies in how different studies measured recurrence.
What the research says
The 2025 meta-analysis included 20 studies covering 4,291 patients to evaluate how well prediction models work for trigeminal neuralgia recurrence 1. The combined results showed a pooled area under the curve of 0.86 for the training set and 0.83 for the validation set, indicating good discriminatory performance 1. Models based on microvascular decompression surgery appeared to perform the best among the different surgical approaches tested 1.
Several specific factors were identified as key predictors for recurrence in these models. These included being 65 years of age or older, having a disease duration longer than 5 years, and experiencing atypical pain patterns 1. The study also highlighted that models based on microvascular decompression generally outperformed other methods 1.
Other research has developed specific models for different treatments. For percutaneous balloon compression, a 2026 study analyzed 448 patients and found that disease duration, pain type, and balloon shape were important factors for predicting recurrence 6. Another 2022 study used MRI features to build a model that could accurately pinpoint the specific blood vessels compressing the nerve, which is a key step in surgical planning 5.
What to ask your doctor
- What specific risk factors apply to my case based on my age and how long I have had pain?
