Objective We aim to measure the intra‐system reliability and the inter‐system agreement between the Facial Nerve Grading 2.0 and Sunnybrook Facial Grading system (SFGS). Method Video clips of 12 patients with facial nerve dysfunction performing a protocol of facial expressions were recorded. Thirteen physicians were asked to evaluate the videos independently using the 2 scales. Results The ICC score for FNG 2.0 and SFGS was 0.820 (95% CI=0.677‐0.931) and 0.831 (95% CI=0.696‐0.936), respectively. The FNG 2.0 and SFGS inter‐system agreement ICC score was 0.959 (95% CI=0.944‐0.970). Conclusion Studies have established high intra‐system reliability for the SFGS, and our results corroborate these. FNG 2.0 similarly shows high intra‐system reliability. As the inter‐system agreement was found to be near perfect in our study, the new FNG 2.0 should be considered as an alternative grading scale for facial nerve palsy.
