Abstract：Objectives To analysis the correlation between House-brackmann Grading System (HBGS)and Facial Nerve Grading System2.0 (FNGS2.0) in evaluation of facial nerve paralysis. Methods Fifty video-recorded facial palsy pa-tients were graded by 3 residents and 3 experts using HBGS and FNGS2.0. Results Agreement percentage between residents for HBGS was 39.5%, and generalized kappa indicated only fair agreement(k=0.30);Agreement percentage between experts for HBGS was 56.5%, and generalized kappa indicated moderate agreement(k=0.43);The difference between the observer groups was statistically significant (P<0.05);.Agreement percentage between residents for FNGS2.0 was 62%, and average ICC indicated excellent agreement(ICC=0.763);Agreement percentage between experts for HBGS was 62.8%, and average ICC indicated excel-lent agreement(ICC=0.785);The difference between the observer groups was not statistically significant (P>0.05);The overall intra-class correlation coefficient (ICC) was 0.760,the Spearman correlation coefficient (SCC) was 0.746 and kappa coefficient was 0.42 (P<0.05);The exact agreements between regional assessment and FNGS 2.0 , were highest for the mouth (71%). Conclusions FNGS 2.0 shows moderate agreement with HBGS. For HBGS the interobserver agreement was influnced by the doctor’s experi-ence;For FNGS2.0, the intraobserver and interobserver agreement was high, with no relation to doctor’s experience.
