The facial function of 1920 patients with peripheral facial palsy was assessed 5397 times with both Sunnybrook and House\u2010Brackmann (H\u2010B) facial grading systems. Grading was done at initial visit, at days 11 to 17 of palsy onset, and at 1\u00a0month, 2\u00a0months, 3\u00a0months, 6\u00a0months, and 12\u00a0months. Statistical evaluation was by Spearman correlation coefficient and box plot analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Spearman correlation coefficient varied from \u22120.81 to \u22120.96, with the weakest correlation found at initial visit. Box plot analysis for all assessments revealed that Sunnybrook scores were widely spread over different H\u2010B grades. With 50% of the results closest to the median, Sunnybrook composite scores varied in H\u2010B grades as follows: H\u2010B I, 100; H\u2010B II, 71 to 90; H\u2010B III, 43 to 62; H\u2010B IV, 26 to 43; H\u2010B V, 13 to 25; and H\u2010B VI, 5 to 14.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Gradings correlated better in follow\u2010up assessments than at initial visit. As shown by the wide overlap of the grading results, subjective grading systems are only approximate. However, a conversion table for Sunnybrook and H\u2010B gradings was obtained and is included in the article. It can be used for further development of facial grading systems.<\/jats:p>\n
