Abstract：
OBJECTIVE: The efficacy of medical treatments and the changes in radiologic imaging before and after treatment have consistently remained pivotal factors. This is particularly critical for surgical procedures, where precise evaluation of disparities pre and postsurgery or the accuracy of implantation is paramount. Based on three-dimensional morphological interests, we provide an automatic quantification evaluation method that delivers an evident base for assessing the outcomes of a widely employed surgical technique, cervical laminoplasty.
METHODS: The sample study included patients who underwent cervical laminoplasty for cervical spondylotic myelopathy/ossification of the longitudinal ligament. We present a superimposition method that facilitates a unique and precise assessment between pre and postsurgery. The degree of expansion was evaluated by the canal volume increase and canal expansion rate after surgery.
RESULTS: There were 31 patients with 112 vertebral segments measured. The target cervical\'s pre and postoperative canal areas were 122.63 ± 30.34 and 196.50 ± 37.10 mm2, respectively (P < 0.001). The average cervical canal expansion rate was 64.42%. The expansion effect of C5 cervical laminoplasty was the maximum (71.01%), and the canal volume of other segments expanded by approximately 60%. The functional outcomes demonstrated significant improvements in symptoms.
CONCLUSIONS: The quantification evaluation method can be utilized for any morphology changes before and after laminoplasty, as it does not lead to errors or variations from different inspection machines or human factors. The automatic method delivers an evident base for assessing the outcomes of a widely employed surgical technique.

摘要：
目的：药物治疗的疗效和治疗前后的影像学变化一直是关键因素。这对于外科手术尤其关键,其中精确评估手术前后的差异或植入的准确性至关重要。基于三维形态兴趣，我们提供了一种自动量化评估方法，为评估广泛采用的外科技术的结果提供了明显的基础，颈椎椎板成形术.
方法：样本研究包括接受颈椎椎管成形术治疗脊髓型颈椎病/纵韧带骨化症的患者。我们提出了一种叠加方法，可以在手术前后进行独特而精确的评估。通过手术后的管容积增加和管扩张率来评估扩张程度。
结果：有31例患者测量了112个椎体节段。目标宫颈术前和术后管区面积分别为122.63±30.34和196.50±37.10mm2（P<0.001）。平均宫颈管扩张率为64.42%。C5颈椎椎板成形术的扩张效果最大(71.01%),其他节段的运河容积扩大了约60%。功能结果显示症状显著改善。
结论：对于椎板成形术前后的任何形态变化，均可采用定量评价方法，因为它不会导致不同检查机器或人为因素的错误或变化。自动方法为评估广泛采用的手术技术的结果提供了明显的基础。
