摘要
Study Design: Prospective study. Objective: To prospectively assess the incidence of dysphagia and to present the serial changes of each finding in the videofluoroscopic swallow study (VFSS) after anterior cervical discectomy and fusion (ACDF). Summary of Background Data: The reported incidence of dysphagia after ACDF has varied widely, and the serial changes of dysphagia using VFSS have not been clearly determined yet. Methods: Data of 47 patients preoperatively and at 1 week and 1 month postoperatively were used for the analyses. The Bazaz dysphagia score and VFSS were checked preoperatively and at 1 week and 1 month postoperatively. The presence of aspiration or penetration, amount of vallecular and pyriform sinus residues, functional dysphagia scale, temporal parameters of oral transit time, pharyngeal transit time, and pharyngeal delay time (PDT) were evaluated from the VFSS data. Results: Incidences of dysphagia measured by the Bazaz dysphagia score were 83.0% at 1 week and 59.6% at 1 month after ACDF. Although the incidence of aspiration was 4.3% and the incidence of penetration was 36.2% at 1 week and 25.5% at 1 month after surgery, none of the patients had aspiration pneumonia. The number of patients with vallecular and pyriform sinus residues significantly increased after ACDF. Further, there were no statistically significant changes at all time points in terms of oral transit time, pharyngeal transit time, and pharyngeal delay time. Conclusions: Dysphagia is common until 1 month after ACDF. Although the incidence of aspiration or penetration in VFSS after ACDF was high, no patient had aspiration pneumonia, which may be because of the intact neurological swallowing mechanism. The typical pattern of dysphagia after ACDF included vallecular and pyriform sinuses filled with postswallow residue, which may result from soft tissue edema and weak constriction of pharyngeal muscles after ACDF.
