Abstract

Dysphagia is a common complication following anterior cervical spine surgery (ACSS). The incidences of dysphagia were variable and controversial. The purpose of this study was to determine the incidence of early dysphagia after ACSS with a new scoring system, and to identify the risk factors of it. A prospective study was carried out and patients who underwent ACSS from March 2014 to August 2014 in our hospital were included in this study. A self-designed dysphagia questionnaire was delivered to all of the patients from the first day to the fifth day after ACSS. Perioperative characteristics of patients were recorded, and incidences and risk factors of dysphagia were analyzed. A total of 104 patients who underwent ACSS were included and incidences of dysphagia from the first to the fifth day after ACSS was 87.5%, 79.81%, 62.14%, 50% and 44.23%, respectively. There was a good correlation between the new dysphagia scoring system and Bazaz scoring system (P < 0.001). Operative time and body mass index (BMI) were the risk factors for dysphagia during the first to the second day postoperatively. However, the dC2-C7angle was the main risk factor for dysphagia from the third to the fifth day after surgery. There were comparatively high incidences of early dysphagia after ACSS, which may be ascribed to operative time, BMI and the dC2-C7 angle.

Highlights

Anterior cervical spine surgery (ACSS) is commonly used for many different kinds of spine conditions, such as trauma and degenerative cervical disease [1,2,3]
The results showed that there was a good correlation between self-designed dysphagia scoring system and Bazaz scale (Table 4 and Fig 1)
Dysphagia Disability Index (DDI) is another popular scale which was used to evaluate the dysphagia after ACSS

Summary

Introduction

Anterior cervical spine surgery (ACSS) is commonly used for many different kinds of spine conditions, such as trauma and degenerative cervical disease [1,2,3]. The anterior approach is easy to relieve pain and recover the function of patients. A variety of complications related to ACSS have been reported. One of the most common complications is dysphagia [4,5,6]. Dysphagia is a transient problem for patient undergoing ACSS, it will affect patient’s function recovery and decreases the postoperative quality of life.
