Postoperative dysphagia (PD) is the most common complication after anterior cervical discectomy and fusion (ACDF). However, few methods were available to determine which muscle groups are associated with PD in details in previous investigations. Local steroid administration has shown some effects on PD in a large number meta-analysis. In this study, we aimed to conduct a prospective randomized-double blinded study to exam the efficacy and the safety of the local steroid administration on ACDF patients, and the also apply the high resolution impedance manometry (HRIM) on patients receiving ACDF for better delineation of the swallowing function. Pressure-flow analysis (PFA), derives pharyngeal pressure flow variables obtained from HRIM were used to analyze the mechanisms of PD.
