中文摘要
背景： 颧区在手术中具有重要意义，因为其骨结构及其与眶下孔（IOF）、冠突（CP）和上颌窦（MS）的关系会影响种植体植入、骨折固定和截骨手术中的解剖定位。然而，这些结构通常被分别评估，使用标准化骨缝标志进行的基于计算机断层扫描（CT）的整合评估仍然有限。本研究旨在建立颧区基于CT的形态学测量框架，并评估性别、年龄和侧别的解剖变异。
方法： 回顾性分析362名全牙列成人（184名男性和178名女性；18-85岁）的鼻窦CT检查，双侧采用多平面和三维重建进行评估。评估了IOF的表面象限位置及其与颧上颌缝（ZMS）端点的距离、在标准化ZMS水平处的颧骨皮质和髓质厚度，以及颧颞缝（ZTS）至CP和MS外侧壁的距离。采用广义估计方程、卡方检验和Bowker检验以及观察者可靠性分析。
结果： 所有七项连续参数在男性中均大于女性（均p < 0.05）。左右差异显著但较小。年龄较大与ZMS下端点至IOF距离较大以及前部和后部皮质厚度较低相关。IOF主要位于A1（71.8%），未见于外侧象限；A3定位在女性和年轻成人中更为常见。向A3进展对应于ZMS上端点至IOF距离增加和下端点至IOF距离减少（均p < 0.001）。前部和后部皮质厚度呈中度相关（ρ = 0.59）。测量和象限分类显示出良好至优秀的可靠性。
结论： 基于表面的IOF定位和标准化骨缝测量提供了一个可重复的框架，整合了IOF定位、区域骨结构、CP和MS外侧壁。这些参考值可为颧种植体植入、中面部骨折固定和截骨手术中基于CT的术前评估和规划提供解剖学参考。
英文摘要
BACKGROUND: The zygomatic region is surgically important because its bone architecture and relationships with the infraorbital foramen (IOF), coronoid process (CP), and maxillary sinus (MS) influence anatomical orientation during implant placement, fracture fixation, and osteotomy procedures. However, these structures have generally been evaluated separately, and integrated computed tomography (CT)-based assessment using standardized sutural landmarks remains limited. This study aimed to establish a CT-based morphometric framework for the zygomatic region and evaluate anatomical variation by sex, age, and side.
METHODS: Paranasal sinus CT examinations of 362 fully dentate adults (184 men and 178 women; 18-85 years) were retrospectively analyzed bilaterally using multiplanar and three-dimensional reconstructions. IOF surface quadrant location and distances from the zygomaticomaxillary suture (ZMS) endpoints, cortical and medullary zygomatic bone thicknesses at a standardized ZMS level, and distances from the zygomaticotemporal suture (ZTS) to the CP and lateral wall of the MS were assessed. Generalized estimating equations, chi-square and Bowker tests, and observer reliability analyses were performed.
RESULTS: All seven continuous parameters were greater in men than in women (all p < 0.05). Significant right-left differences were small. Older age was associated with a greater ZMS inferior endpoint-to-IOF distance and with lower anterior and posterior cortical thicknesses. The IOF was predominantly located in A1 (71.8%) and was absent from the lateral quadrants; A3 localization was more frequent in women and younger adults. Progression toward A3 corresponded to increased superior and decreased inferior ZMS endpoint-to-IOF distances (both p < 0.001). Anterior and posterior cortical thicknesses were moderately correlated (ρ = 0.59). Measurements and quadrant classification demonstrated good-to-excellent reliability.
CONCLUSIONS: Surface-based IOF mapping and standardized sutural measurements provided a reproducible framework integrating IOF localization, regional bone architecture, the CP, and the lateral wall of the MS. These reference values may provide an anatomical reference for CT-based preoperative assessment and planning in zygomatic implant placement, midfacial fracture fixation, and osteotomy procedures.
