Raw data from bone volume measuraments and split classifications

Bone volume assessment and its linking to the split pattern is a recent topic in the literature. This process demands powerful resources to segment the region of interest from the tomography and render a 3D object. Furthermore, several factors are pertinent: device parameters, bone density, medullar architecture, segment surrounding structures, higher attenuation materials, object post-processing, and straightforward workflow. This study aimed to evaluate bone volume in the Sagittal Split Osteotomy (SSO). Preoperative and postoperative CT scans of 82 patients (164 SSO) were used in 3D Slicer 5.6 software. In the preoperative data, the CT and CBCT scans performed a strict bone volume analysis(mm³). On postoperative data, a classification attributed to the fracture: I (most desired), II, III, or IV (totally undesired/bad split), resulting in 4 groups: CT Class II, CT Class III, CBCT Class II, and CT Class II. The split pattern difference was statistically confirmed in the CT Class III group, whereas type I had the highest bone volume. The ANOVA test (p=0.088) was confirmed by Tukey's analysis (P&lt;0.05). In conclusion, the study demonstrated a reproducible method for bone segmentation and volume measurement (mm³). Further studies are needed to broaden comprehension of the methodology for bone volume assessment.骨体积评估及其与劈开模式的关联是当前文献中的热门研究主题。该流程需要依托高性能计算资源，从断层影像中分割出感兴趣区域并渲染为三维对象。此外，诸多因素与之相关：设备参数、骨密度、髓腔结构、周围结构分割、高衰减物质、对象后处理以及简洁流畅的工作流程。本研究旨在评估矢状劈开截骨术（Sagittal Split Osteotomy, SSO）中的骨体积。本研究使用3D Slicer 5.6软件，对82名患者的术前及术后CT扫描数据（共164例SSO手术样本）进行分析。在术前数据中，针对CT及锥形束计算机断层扫描（Cone Beam Computed Tomography, CBCT）影像开展了严格的骨体积分析（单位：mm³）。针对术后数据，则依据骨折劈开模式进行分级：I级（最理想）、II级、III级或IV级（完全不理想/劈开失败），最终分为四组：CT II级组、CT III级组、CBCT II级组以及CT II级组。CT III级组的劈开模式差异具有统计学意义，而I级劈开模式对应的骨体积最高。方差分析（Analysis of Variance, ANOVA，p=0.088）经Tukey事后检验验证（P<0.05）。综上，本研究证实了一种可重复的骨分割与体积测量方法（单位：mm³）。未来仍需开展更多研究，以深化对骨体积评估方法的认知。
