■颅孔的评估是与涉及颅底结构的病理相关的客观诊断和治疗研究的重要组成部分。卵圆孔的研究不仅对解剖发育具有重要意义,而且具有深远的外科意义。比如三叉神经痛,和诊断肿瘤和各种类型的癫痫的重要性。它在神经周肿瘤手术的细针抽吸技术中变得相关,用于癫痫发作的脑电图分析,和治疗程序,如经皮三叉神经根切断术治疗三叉神经痛。
■神经外科的一项横断面研究,专科医院,LaRaza国家医疗中心,墨西哥城,在2023年7月至2024年3月期间,70例年龄>18岁的患者接受了一次颅骨计算机断层扫描.该研究包括具有足够扫描质量和最佳颅底孔可视化的患者。使用Inobitec的DICOM文件查看器对断层图像进行测量。MicrosoftExcel中的数据分析得出平均值,标准偏差,卵圆孔形态参数的95%置信区间(CI)。
■对70例患者的断层摄影分析显示,卵圆孔共140例,平均分为25名男性(35.7%)和45名女性(64.3%)。最大前后直径的测量,横向直径,所有孔的表面积如下:6.61±0.25mm(95%CI),3.97±0.21mm(95%CI),和20.84±1.58mm2(95%CI),分别。获得了右侧和左侧的特定测量结果:对于右侧,最大前后径和横向径分别为6.59±0.26mm(95%CI)和3.89±0.21mm(95%CI),分别,表面积为20.38±1.62mm2(95%CI)。对于左侧,测量值为6.63±0.24mm(95%CI),4.05±0.21mm(95%CI),最大前后直径为21.31±1.55mm2(95%CI),横向直径,和表面积,分别。前后直径和横向直径的最大和最小尺寸为10.67mm,4.41mm,7.09毫米和2.36毫米,分别,相应的表面积范围为10.16mm2-44.13mm2。卵圆孔与棘孔之间的平均最小距离为2.32±0.24mm(95%CI)。在男性中,卵圆孔的平均大小为23.66±1.61,比女性的平均大小(19.28±1.45)大22%(P=0.0001)。
■卵圆孔是颅底的主要解剖结构之一,除此之外,它很复杂,无法直接进行临床评估,通过形态计量学分析可以获得有用的信息。本研究提供了具有形态学模式的特定解剖数据,以增加对墨西哥人群卵圆孔特征的理解。这些旨在有助于寻求认识形态计量学,从而能够计划中颅窝的神经外科手术。
UNASSIGNED: The assessment of cranial foramina is an important part of the objective diagnostic and therapeutic study relevant to pathologies involving structures of the skull base. The study of the foramen ovale not only holds significance for anatomical development but also bears profound surgical importance, such as in trigeminal neuralgia, and diagnostic importance in tumors and various types of epilepsy. It becomes relevant in fine-needle aspiration techniques in perineural tumor procedures, for electroencephalographic analysis in seizures, and therapeutic procedures such as percutaneous trigeminal rhizotomy for trigeminal neuralgia.
UNASSIGNED: A cross-sectional study at the Department of Neurosurgery, Specialties Hospital, La Raza National Medical Center, Mexico City, involved 70 patients aged >18 years who underwent a single skull computed tomography scan between July 2023 and March 2024. Patients with sufficient scan quality and optimal visualization of skull base foramina were included in the study. Measurements of tomographic images were taken using Inobitec\'s DICOM file viewer. Data analysis in Microsoft Excel yielded mean, standard deviation, and 95% confidence interval (CI) for morphometric parameters of the foramen ovale.
UNASSIGNED: Analysis of tomographies from 70 patients revealed a total of 140 foramen ovale, evenly split between 25 males (35.7%) and 45 females (64.3%). The measurements for the maximum anteroposterior diameter, transverse diameter, and surface area of all foramina were as follows: 6.61 ± 0.25 mm (95% CI), 3.97 ± 0.21 mm (95% CI), and 20.84 ± 1.58 mm2 (95% CI), respectively. Specific measurements for the right and left sides were obtained: for the right side, 6.59 ± 0.26 mm (95% CI) and 3.89 ± 0.21 mm (95% CI) for the maximum anteroposterior and transverse diameters, respectively, and 20.38 ± 1.62 mm2 (95% CI) for the surface area. For the left side, the measurements were 6.63 ± 0.24 mm (95% CI), 4.05 ± 0.21 mm (95% CI), and 21.31 ± 1.55 mm2 (95% CI) for the maximum anteroposterior diameter, transverse diameter, and surface area, respectively. The maximum and minimum dimensions for anteroposterior and transverse diameters were 10.67 mm, 4.41 mm, 7.09 mm and 2.36 mm, respectively, with a corresponding range for the surface area of 10.16 mm2-44.13 mm2. The average minimum distance between the foramen ovale and the foramen spinosum was 2.32 ± 0.24 mm (95% CI). In males, the average size of the foramen ovale was 23.66 ± 1.61, which was 22% larger than the average size in females (19.28 ± 1.45) (P = 0.0001).
UNASSIGNED: The foramen ovale is one of the main anatomical structures of the skull base, and besides that, it is complex and not directly accessible for clinical evaluation, useful information can be obtained through morphometric analysis. The present study provides specific anatomical data with morphological patterns to increase the understanding of the characteristics of the foramen ovale in the Mexican population. These are intended to be helpful in the pursuit of acknowledging the morphometrics and thus being able to plan neurosurgical procedures in the middle cranial fossa.
