AB  - OBJECTIVE: To modify the conventional methods of grooving and direction during 
      the single-door cervical laminoplasty (SDCL) in the subaxial cervical spine. 
      METHODS: The distance between the left and the right lamina-lateral mass junction 
      at the upper, middle, and lower levels of each segment (DLL-U, DLL-M, DLL-L), 
      angle between the posterior edge of the vertebral body and the lamina (AVL) and 
      thickness of lamina (TL) were measured in the transverse plane. The parameters of 
      preoperative computed tomography scans of 200 patients who had undergone SDCL 
      were measured. The patients were divided into male and female groups and 
      developmental canal stenosis (DCS) and non-DCS (NDCS) groups. RESULTS: DLL-M 
      gradually increased from the cranial to the caudal except for C7, and DLL-L > 
      DLL-M > DLL-U in each vertebra. AVL increased from C3 to C7, TL decreased from C3 
      to C5 and increased from C5 to C7, with both parameters showing no significant 
      differences between the left and right sides. AVL of the DCS group was less than 
      that of the NDCS group (P < 0.01). CONCLUSIONS: In the SDCL, the ideal surgical 
      trough should be several discontinuous lines sloping from top to bottom, rather 
      than a straight line. The abduction angle during drilling should gradually 
      increase from C3 to C7 in the SDCL averaging 40 degrees. This method mentioned 
      above improves the efficiency of the operation with less blood loss as an 
      extended cut into the lateral mass is avoided.
