Abstract：Objective To investigate the clinical effects and surgical complications of unilateral and bilateral open-door cervical expansive laminoplasty for multilevel cervical degenerative diseases. Methods A retrospective study was carried on 73 patients with multilevel cervical degenerative disease treated by cervical expansive laminoplasty from January 2008 to January 2013. According to different surgical procedures, they were divided into 2 groups, unilateral open-door group (32 patients) and bilateral open-door group (41 patients). The operation time, intraoperative estimate blood loss, Japanese Orthopaedic Association (JOA) scoring improvement rate and postoperative complications were compared between two groups. Results All patients were followed up with an average period of 34.8 months (range, 24 to 52 months), and three patients were lost to follow up after two years later. Operation time and intraoperative estimate blood loss in unilateral open-door group were less than those in bilateral open-door group (P <0.05). The average JOA scoring improvement rate was 66% ± 18% for unilateral open-door group and 58% ± 27% for bilateral open-door group, there was no significant difference between two groups (P>0.05). In unilateral open-door group, incidence of C5 nerve root palsy, cerebrospinal fluid leakage or surgical site infection (6%, 3%, 3%) was lower than that in bilateral open-door group (7%, 10%, 5%) respectively, but the differences between two groups had no statistical significance (P >0.05); Incidence of axial symptoms in unilateral open-door group (31%) was higher compared with that in bilateral open-door group (12%), there was statistical difference between two groups (P <0.05). Conclusions Both unilateral and bilateral open-door cervical expansive laminoplasty are effective for the treatment of multilevel cervical degenerative diseases, in which the former has shorter operation time and less intraoperative estimate blood loss, while the latter has lower incidence of axial symptoms.
