Abstract: Objective  To analyze the effect of anterior cervical discectomy and fusion(ACDF) and anterior cervical corpectomy and fusion(ACCF) in the treatment of patients with multilevel cervical spondylopathy and the influence on cervical spine range of motion(ROM) and postoperative complications. 
Methods  The clinical data of 60 patients with multilevel cervical spondylopathy who received surgery in our hospital were retrospectively analyzed. According to different operation methods, they were divided into ACDF group(n=28) and ACCF group(n=32). The duration of operation, intraoperative blood loss, duration of hospital stay and postoperative complications of patients in two groups were observed. The visual analogue(VAS) score and the Japan Orthopaedic Association(JOA) score were used to evaluate the pain degree and neurological function of patients in two groups, and the cervical spine curvature and cervical spine ROM of patients in two groups before and after operation were observed and recorded. 
Results  The intraoperative blood loss in ACCF group was significantly higher than that in ACDF group, and the difference was statistically significant(P＜0.05). The duration of operation in ACDF group was significantly lower than that of ACCF group, and the difference was statistically significant(P＜0.05). There was no significant difference in JOA scores between ACDF and ACCF groups before and at 3 months after operation(P＞0.05), and JOA score of the two groups at 3 months after operation was significantly higher than that before operation, suggesting significant difference(P＜0.05). There were significant differences in cervical spine curvature and ROM between ACDF and ACCF groups before and at 3 months after operation(P＜0.05). Significant difference was found in the cervical spine curvature and ROM before and at 3 months after operation(P＜0.05). No complication occurred in ACDF group, and complication was observed in 6 cases in ACCF group, including 3 cases of hoarseness, 2 cases of incision infection and 1 case of non-fusion; the total incidence was statistically significant(P＜0.05). 
Conclusion  ACDF and ACCF can significantly improve the ROM of the cervical spine, and both have good effects. However, patients undergoing ACDF have less intraoperative blood loss, shorter duration of operation, and fewer complications.
