OBJECTIVES: This study aimed to review the incidence, outcomes and treatment of delayed facial nerve palsy (DFP) following otological surgery. METHODS: MEDLINE, Pubmed, Embase and The Cochrane Central Register of Controlled Trials were searched up to 10 May 2024. A systematic review was conducted per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines of studies reporting on DFP following otological surgery. The risk of bias was assessed using the JBI critical appraisal tools. RESULTS: Forty-nine articles were included with 201 instances of DFP following 24,917 operations from 1967 to 2021. The mean day of onset post-operatively was 8.4. 93 per cent of episodes fully recovered, with most cases taking between eight days and one month to recover. CONCLUSION: Many theories of the pathogenesis of DFP exist. It is rare and has an excellent prognosis following treatment with corticosteroids with or without anti-viral therapy.
