Abstract
Anterior cervical spine surgery is a common procedure for fusions and/or discectomies. Postoperative dysphonia and dysphagia are known complications. In this study, we examined the frequency and outcomes of these complications in this patient population. Patients planned to receive anterior cervical spine surgery between 01.03.2010 and 28.02.2011 at the Department of Neurosurgery, St. Gallen were prospectively included. Patients were evaluated using laryngoscopy, fiberoptic endoscopic evaluation of swallowing (FEES), voice field measurements and validated questionnaires. From the 53 patients included in the study, 40had at least one complete follow-up examination. The frequency of postoperative dysphonia due to recurrent nerve palsy was 4/40(10 %), although this was temporary in 3patients. FEES revealed a pathological result in 18.9 % of patients. Postoperative Swallowing Quality of Life Questionnaire (Swal-QoL) scores were significantly lower. At a frequency of 10 %, dysphonia due to recurrent nerve palsy is a relevant complication in cervical spine surgery, albeit temporary in most cases. Postoperative dysphagia is common and should be evaluated and treated during follow-up.
