To compare and evaluate, using computer-aided volumetric measurements, the accuracy and reliability of nonpreformed mesh plates (NPMPs) versus 3-dimensionally preformed titanium mesh plates (PMPs) in posttraumatic orbital volume restoration.
Facial coronal computed tomographic scan slices from 20 patients (10 in the NPMP and 10 in the PMP group) were used to measure bony orbital volume using OsiriX Medical Image software (version 3.3.2, www.osirix-viewer.com). The procedure was performed on both orbits; thereafter, the volume of the contralateral health orbit was used as a control for comparison in the 2 groups of patients. The difference in orbital volume between the 2 groups and between the reconstructed versus uninjured side in both groups have been statistically correlated.
The mean orbital volume between the reconstructed (19.215 mL in NPMP and 21.791 mL in PMP) and the contralateral uninjured side (18.955 mL in NPMP and 21.710 mL in PMP) was not statistically significant (P > 0.05). The mean orbital volumes of the reconstructed orbits were 19.215 mL in the NPMP and 21.791 mL in the PMP group, with no statistically significant difference (P > 0.05). The volume data of the reconstructed orbit fitted that of the contralateral uninjured orbit with an accuracy of a maximum of 1.85 mL in the NPMP group and 2.5 mL in the PMP group.
The current study demonstrated that there were no significant differences in the orbital volume restoration using either technique. In fact, both techniques allow for close reproduction of natural orbital volume and shape, and its use in posttraumatic orbital wall reconstruction was successful.
运用计算机辅助体积测量法，比较并评估非预制网片（NPMPs）与三维预制钛网片（PMPs）在创伤后眼眶容积修复中的准确性和可靠性。
使用OsiriX医学影像软件（版本3.3.2，www.osirix-viewer.com）对20例患者（NPMP组10例，PMP组10例）的面部冠状位计算机断层扫描切片进行测量，以获取眼眶骨容积。对双侧眼眶均进行该操作；之后，将对侧健康眼眶的容积作为对照组，用于两组患者的比较。两组之间以及两组中重建侧与未受伤侧眼眶容积的差异进行了统计学相关性分析。
重建侧（NPMP组为19.215 mL，PMP组为21.791 mL）与对侧未受伤侧（NPMP组为18.955 mL，PMP组为21.710 mL）的平均眼眶容积差异无统计学意义（P > 0.05）。NPMP组重建眼眶的平均容积为19.215 mL，PMP组为21.791 mL，差异无统计学意义（P > 0.05）。重建眼眶的容积数据与对侧未受伤眼眶的数据拟合良好，NPMP组最大误差为1.85 mL，PMP组为2.5 mL。
本研究表明，两种技术在眼眶容积修复方面无显著差异。事实上，两种技术都能紧密再现天然眼眶的容积和形状，且在创伤后眼眶壁重建中的应用是成功的。
