IntroductionDysphagia is one of the most common complications of anterior cervical spine surgery. Local steroid was widely used to reduce the postoperative swallowing pain. However, the effect of local steroid application on dysphagia after anterior cervical spine surgery was still uncertain.Materials And MethodsWe searched Medline (PubMed), Embase and the Cochrane Library on July 27, 2021 for studies investigating the effect of local steroid application on dysphagia after anterior cervical spine surgery from their date of inception to 2021. The relative risk or weighted mean difference with 95% confidence interval was recorded as a summary statistic consist of postoperative dysphagia, swallowing VAS scores, SWAL-QOL scores, PSTSI, and steroid related complications.ResultsThis meta-analysis included 7 RCT studies involving 254 patients in the steroid group and 232 patients in the placebo group. Results showed local steroid group had less patients with dysphagia, lower swallowing VAS scores and less severe of prevertebral soft-tissue edema on the fourth day after surgery. No significant difference in non-fusion rate between the two groups was observed. And all included studies had no serious steroid related complications reported.ConclusionsThe use of local steroid in anterior cervical spine surgery could reduce the early postoperative dysphagia without serious steroid related complication. However, the safety of local steroid application still need further studies with larger samples.© 2022.
