Crista galli is extremely important in the endoscopic transcribriform approaches and some extradural approaches. Because of its clinical significance, the morphometric properties of crista galli should be well known. In this study, it was aimed to examine the morphometry and the pneumatization incidence of the crista galli in cone beam computed tomography (CBCT) images.
In this retrospective study, the length and width of the crista galli were measured in CBCT images of 300 healthy individuals. Besides, the presence of crista galli pneumatization was examined.
The length and width of the crista galli were determined to be as 14.03 ± 2.93 mm and 3.73 ± 1.48 mm, respectively. Pneumatized crista galli was detected in 53 out of 300 individuals (17.67%). There was no statistical difference between the presence of pneumatization and both length and width values of the crista galli (P = 0.876 and P = 0.478, respectively). In addition, no relationship was determined between age and the presence of pneumatization (P = 0.167).
In this study, it is seen that the length (range: 6.00-23.40 mm) and width (range: 1.40-8.00 mm) of crista galli are in a very wide range. Besides, it is seen in the literature that the incidence of crista galli pneumatization is in a very wide range (2.4% to 66.6%). Based on the available data, it will not be possible to determine a specific range of values for crista galli morphometry. Therefore, the authors think that CT imaging is extremely important in preoperative evaluation.
鸡冠在经鼻内镜颅底入路和一些颅外入路中非常重要。由于其临床意义，鸡冠的形态特征应该被很好地了解。本研究旨在通过锥形束 CT（CBCT）图像检查鸡冠的形态和气化发生率。
在这项回顾性研究中，测量了 300 名健康个体的 CBCT 图像中鸡冠的长度和宽度。此外，还检查了鸡冠气化的存在情况。
鸡冠的长度和宽度分别确定为 14.03±2.93mm 和 3.73±1.48mm。在 300 名个体中，有 53 名（17.67%）发现了气化的鸡冠。鸡冠气化的存在与鸡冠的长度和宽度均无统计学差异（P=0.876 和 P=0.478）。此外，年龄与鸡冠气化的存在之间也未确定任何关系（P=0.167）。
在这项研究中，我们发现鸡冠的长度（范围：6.00-23.40mm）和宽度（范围：1.40-8.00mm）非常广泛。此外，文献中报道鸡冠气化的发生率也非常广泛（2.4%-66.6%）。基于现有数据，鸡冠形态学的特定范围值无法确定。因此，作者认为 CT 成像在术前评估中极为重要。
