Introduction: A prospective study was conducted to evaluate the incidence and to identify risk factors for the postoperative dysphagia after anterior cervical spine surgery.
material and method: Postoperative dysphasia and several radiographical parameters were prospectively investigated for 87 patients who underwent anterior cervical surgery in our institution. Dysphasia was evaluated by using Bazaz dysphagia score at the postoperative 6 months and 1year. Risk factors of postoperative dysphasia were estimated by multivariate analysis.
result: Postoperative dysphagia was observed in 25 patients (31.3%) at postoperative 6 months and remained in 22 patients (25.3%) at postoperative one year. Logistic regression analysis using remained dysphagia one year after surgery as an objective variable indicated that multi-level fixation, increased C2-7 lordosis angle, and neck pain were identified as risk factors.
conclusions: This study identified three risk factors. The only risk factor that could be controlled by the surgeon was the increase in C2-7 lordotic angle.
