The morphological pattern of the GTs is still controversial, and therefore, the study of its morphology using cone beam computed tomography (CBCT) plays a valuable role in resolving the controversy. AIM To assess the morphological pattern, dimensions and position of the GTs using CBCT among a selected Saudi population. METHODS CBCT records of 155 Saudi subjects (49 female and 106 male) were used to assess the pattern and size of the GTs and to determine the distance from the apices of the lower central incisors to the superior border of the incisors (I-SGT) and the distance from the inferior border of the GTs to the menton (IGT-M). RESULTS The results of this study showed that the most common morphological pattern was of two superior GTs and a rough impression below them (36.8%), followed by two superior GTs and a median ridge representing fused inferior GTs below them (22.6%) and a single median eminence or projection (20%). The classically described pattern, of two superior and two inferior GTs placed one above the other, was found in only 14.2% of cases, while 6.4% of the studied cases had no GTs. The mean width and height were 6.23 ± 1.93 mm and 6.67 ± 3.04 mm, respectively, while the mean I-SGT and IGT-M measurements were 8.26 ± 2.7 mm and 8.13 ± 3.07 mm, respectively. CONCLUSION The GTs are a controversial anatomical landmark with wide variation in their morphological pattern. The most common pattern among the studied Saudi sample was of two superior GTs and a rough impression below them, and there were no significant differences between males and females.展开更多
目的:分析右侧颈内静脉输液港导管置入长度的影响因素,并建立基于右侧胸骨第三肋间隙作为解剖标志测量导管长度的回归方程。方法:收集西安交通大学第一附属医院2017年9月至2018年7月行右侧颈内静脉植入式输液港的患者共190例为研究对象...目的:分析右侧颈内静脉输液港导管置入长度的影响因素,并建立基于右侧胸骨第三肋间隙作为解剖标志测量导管长度的回归方程。方法:收集西安交通大学第一附属医院2017年9月至2018年7月行右侧颈内静脉植入式输液港的患者共190例为研究对象,均采用术中透视确定导管长度,并记录穿刺部位至右侧胸骨第三肋间隙的距离(SK-ICS)。采用Pearson相关分析法分析实际置管长度与患者的年龄、身高、体质量、体质指数(body mass index,BMI)及SK-ICS的相关性,通过多元线性回归分析建立回归方程,并与其余3种常用公式进行对比。结果:导管长度与患者的身高、体质量及SK-ICS值存在正相关(P<0.05),与BMI呈负相关(P<0.05)。通过多元线性回归分析得到回归方程:L=1.01×SK-ICS+0.151。该方程估算值与实际长度相比无明显差异(P>0.05),而其余3种公式估算值均长于实际值。回归方程的绝对误差与百分比值均较低,预测置管长度准确性较高。结论:通过使用体表标志建立的回归方程对导管长度的估算具有一定的临床指导价值和推广意义。展开更多
