Longitudinal Analysis of the Use of Facial Reanimation Procedures for Bell's Palsy.

Background: Treatment of Bell's palsy ranges from medical management with high-dose corticosteroids to complex facial reanimation procedures. Objective: To characterize the number of static, dynamic, and combined facial reanimation procedures for the management of Bell's palsy using a national database over time. Methods: This retrospective cohort study included patients in the 2013-2020 National Surgical Quality Improvement Project database with a postoperative diagnosis of Bell's palsy. Cases were categorized as involving only static, only dynamic, and a combination of static and dynamic procedures. Chi-square or Fisher's exact tests were performed for patient demographics, and linear regressions were created to evaluate utilization trends. Results: In total, 294 patients were identified. There was no significant difference in patient sex and comorbidities between these treatment groups. Of the 294 patients, 101 received both types of procedures, 107 received only dynamic procedures, and 86 received only static procedures. The trendlines for all treatment groups were significantly positive (B = 1.27 for both, B = 0.89 for dynamic only, and B = 1.01 for static only). Conclusion: In this study of a national surgical database, an increase in static, dynamic, and combined treatments for patients with Bell's palsy was found.
