Abstract | OBJECTIVE: METHODS: A literature search was conducted in PubMed, Embase, Ichushi-Web, and Cochrane Central Register of Controlled Trials. Published randomized controlled trial and observational studies, which compared the combination of intratympanic corticosteroids with systemic corticosteroid versus systemic corticosteroid for Bell's palsy and Ramsay Hunt syndrome, were included for meta-analysis. The primary outcome was non-recovery at the end of the study follow-up. Data was analyzed using Review Manager software, and pooled odds ratio with 95% CI were calculated. RESULTS: Three randomized controlled trial and two cohort studies met the eligible criteria, and 350 individuals included for meta-analysis. The timing of intratympanic corticosteroid was varied from once or twice a week to consecutive 10-days. Patients treated with combination of systemic corticosteroids and intratympanic corticosteroids were likely to achieve recovery of normal facial function (OR = 0.36 [95% CI 0.12-1.14]). The subgroup analysis of the timing revealed that daily ITST reduced non-recovery (OR = 0.14 [95% CI 0.04-0.50). However, non-daily ITST did not reduced non-recovery (OR 0.93 [95% CI 0.37-2.34]). CONCLUSION: Intratympanic corticosteroid have a potential to reduce non-recovery in patients with Bell's palsy and Ramsay Hunt syndrome. The methods of intratympanic corticosteroid varied among included studies. Further well-designed randomized controlled trial is needed to confirm the effectiveness and to identify an adequate method of intratympanic corticosteroid in these patients.
