Thirty\u2010eight patients who underwent ultrasonic bone curette\u2010assisted dome\u2010like laminoplasty were defined as ultrasonic bone curette group (UBC), and 28 patients who underwent traditional high\u2010speed drill\u2010assisted dome\u2010like laminoplasty were defined as high\u2010speed drill group (HSD). Patient characteristics such as age, sex, body mass index (BMI), symptomatic duration, and other information like the type of OPLL, the time of surgery, blood loss, C<jats:sub>2<\/jats:sub>\u2013C<jats:sub>7<\/jats:sub> Cobb angle change and complications were all recorded and compared. The Japanese Orthopaedic Association (JOA) score, the nerve root functional improvement rate (IR), and the visual analogue scale (VAS) were used to assess neurological recovery and pain relief. The change of the distance between the apex of ossification and a continuous line connecting the anterior edges of the lamina was measured to assess the spinal expansion extent. The measured data were statistically processed and analyzed using SPSS 21.0 software, and the measurement data were expressed as mean\u2009\u00b1\u2009SD.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In ultrasonic bone curette (UBC) group and high\u2010speed drill group (HSD) group, the average time for laminoplasty was 52.3\u2009\u00b1\u200918.2\u2009min and 76.0\u2009\u00b1\u200921.8\u2009min and the mean bleeding loss volume was 155.5\u2009\u00b1\u200941.3\u2009mL and 177.4\u2009\u00b1\u200954.7\u2009mL, respectively, with a statistically significant difference between the groups. Both groups demonstrated a significant improvement in neurological function. However, the VAS score in UBC group was lower than in HSD group at the 6\u2010month follow\u2010up (<jats:italic>P<\/jats:italic> &lt;\u20090.05), but there was no significant difference at 1\u2010year follow\u2010up. We found that the loss of lordosis was 1.5\u00b0\u2009\u00b1\u20091.0\u00b0 in UBC group, which is significantly lower than that of HSD group at 1\u2010year follow\u2010up (3.8\u00b0\u2009\u00b1\u20091.2\u00b0, <jats:italic>P<\/jats:italic> &lt;\u20090.05).
