BACKGROUND/PURPOSE: Expansive open-door laminoplasty (EOLP) is a useful technique for multiple-level cervical spondylotic @entity602 . The common @entity260 of EOLP include moderate to severe @entity4048 , @entity393 , @entity2244 . We modified the surgical technique to lessen these complications. This study is aimed to elucidate the efficacy of modified techniques to lessen the complications of traditional procedures. METHODS: We collected data from 126 consecutive @entity1 treated at our institution between August 2008 and December 2012. Of these, 66 @entity1 underwent conventional EOLP (CEOLP) and the other 60 @entity1 underwent modified EOLP (MEOLP). The demographic and preoperative data, @entity158 visual analog scale scores at 2 weeks and 3 months postoperatively, clinical outcomes evaluated using Nurick score and Japanese Orthopedic Association recovery rate at 12 months postoperatively, and radiographic results assessed using plain films at 3 months and 12 months postoperatively for both groups were compared and analyzed. RESULTS: There were no significant differences regarding the preoperative condition between the CEOLP and MEOLP groups (p  >  0.05). The Japanese Orthopedic Association recovery rate of the MEOLP group was 70.3%, comparable to the result of the other group (70.2%). @entity282 , @entity393 , and loss of @entity1515 of cervical curvature decreased significantly in the MEOLP group (p  <  0.05). The complications of temporary @entity2244 found in the CEOLP group did not exist in the MEOLP group. CONCLUSION: MEOLP is a minimally invasive surgical method to treat multiple-level cervical spondylotic @entity602 , which decreases @entity260 effectively.

Modified expansive open-door laminoplasty technique improved postoperative XXXX and cervical range of motion.
