Abstract：
OBJECTIVE: To provide a comprehensive analysis for accurate screw size selection and insertion angle during surgical procedures.
METHODS: In this retrospective study, a total of 120 patients participated, resulting in the analysis of 240 occipital condyles using coronal, sagittal, and axial planes on CT scans. Statistical evaluation was performed using the Wilcoxon rank-sum test, with p < 0.05 considered statistically significant.
RESULTS: The mean sagittal length and height were measured at 17.2 ± 1.7 mm and 9.1 ± 1.5 mm, respectively. The average condyle angle, a crucial factor for screw insertion, was assessed at 38.0 ± 5.5 mm in length, 19.6 ± 2.6 mm in width, and 9.5 ± 1.0 mm in height. Condyle height in the anterior and posterior hypoglossal canals was measured at 10.8 ± 1.4 mm and 9.0 ± 1.4 mm, respectively. Screw angle and condyle width were statistically smaller in females compared to the male population.
CONCLUSIONS: The OC is a significant anatomical structure in the craniovertebral junction, playing a crucial role in stability. The obtained morphological values are applicable to the Turkish population and offer statistically significant findings for preoperative planning involving occipital condyle screw instrumentation.

摘要：
目的：本研究旨在阐明土耳其人群枕骨髁的解剖形态，厚度,和成角。目的是为手术过程中准确选择螺钉尺寸和插入角度提供全面分析材料和方法：在这项回顾性研究中，共有120名患者参加，结果用冠状分析了240个枕骨髁，矢状,和CT扫描的轴向平面。使用Wilcoxon秩和检验进行统计评估，p<0.05被认为具有统计学意义。
结果：测量的平均矢状长和高度分别为17.2±1.7mm和9.1±1.5mm，分别。平均髁角,螺钉插入的关键因素，长度为38.0±5.5毫米，宽度19.6±2.6mm,和9.5±1.0毫米的高度。舌下管前后髁突高度分别为10.8±1.4mm和9.0±1.4mm,分别。与男性人群相比，女性的螺钉角度和髁宽度在统计学上较小。
结论：OC是颅骨交界处的重要解剖结构，在稳定中发挥着至关重要的作用。获得的形态学值适用于土耳其人群，并为涉及枕骨髁螺钉器械的术前计划提供了具有统计学意义的发现。
