The effect of local intraoperative corticosteroid application on postoperative dysphagia following anterior cervical spine surgery

AbstractDysphagia is a common complication following anterior cervical spine surgery (ACSS). Although several literatures have reported the potential benefit of local corticosteroid application on dysphagia, its safety and efficacy are still unclear. A systematic review was performed aiming to evaluate the evidence of local corticosteroid application in prevention or treatment of postoperative dysphagia following ACSS. A systematic search was performed in September 2018 in PubMed and Embase database. The following information was extracted: study investigator, year of publication, number of patients, study design, inclusion/exclusion criteria, administration protocol of steroid, type of surgical procedure, number of levels performed, assessment methodology of dysphagia, radiologic assessment of prevertebral soft tissue swelling (PSTS), follow-up time points, outcome of dysphagia, and corticosteroid-related complications. Qualitative synthesis was performed. Finally, 5 studies met the inclusion/exclusion criteria. Four studies found that local corticosteroid application could decrease the incidence and magnitude of postoperative dysphagia while 1 study showed no effect on dysphagia significantly at 6 weeks and 3 months follow-up time. A total of 2325 patients received local corticosteroid intraoperatively; no early corticosteroid-related complication was reported. Totally, 4 adverse events occurred in long-term follow-up time, including 2 bone nonunion at 1.5 and 2.5 years pos...
