Abstract

Purpose: Our study aims to investigate three parts of the intracranial cavity, their distances to essential anatomical landmarks, and the correlations between these distances with sex, laterality, and surgical significance.

Methods: The cranial nerve foraminae and essential surgical landmarks of each fossa were investigated bilaterally in 30 adult formalin-fixed cadaveric heads. Measurements, including lengths, depths, diameters, and horizontal distances to each other, to the midline of the skull, and to the outer lateral margin of the skull, were recorded on both sides.

Results: The optic canal (OC) depth, internal auditory meatus (IAM) width, CNVII and CNIX diameters, and accessory hypoglossal canal (HC) distance were significantly greater on the left side (p < 0.05). CNVI length, CNV diameter, CNXI length, and the distances of the HC and accessory HC from the skull were significantly greater on the right side (p < 0.05). In males, correlations were found between the length of the left CNVIII and the right IAM diameter (r = 0.864, p = 0.001), right CNVIII length (r = 0.709, p = 0.022), right accessory HC length (r = 0.847, p = 0.016), and right-sided skull distance (r = 0.829, p = 0.042). In females, correlations were noted between IAM depth and length, right IAM location relative to the skull, left CNIX and CNX lengths, left CNXII length, left accessory HC location relative to the skull, and accessory HC length.

Conclusions: The findings of the current study indicate inherent asymmetry, sexual dimorphism, and variability in certain cranial nerves among cadaveric heads, which could have implications for surgical procedures, neuroanatomical studies, and clinical assessments. The study revealed side disparities and correlations within cranial fossa formations and essential surgical landmarks in both genders.

固定尸体颅底颅腔内的颅窝调查:与性别、侧位和临床意义的关联。
目的:我们的研究旨在调查颅腔内的三个部位、它们与重要解剖标志的距离,以及这些距离与性别、侧位和手术意义的相关性:方法:对 30 个经福尔马林固定的成人尸体头颅的颅神经孔板和每个颅窝的重要手术标志物进行了双侧调查。测量结果包括两侧头颅的长度、深度、直径以及相互之间、与颅骨中线和与颅骨外侧缘之间的水平距离:结果:左侧视神经管(OC)深度、内耳道(IAM)宽度、CNVII 和 CNIX 直径以及舌下神经管(HC)辅助距离均显著大于右侧(p 结论:左侧视神经管(OC)深度、内耳道宽度、CNVII 和 CNIX 直径以及舌下神经管辅助距离均显著大于右侧(p):目前的研究结果表明,尸体头部的某些颅神经存在固有的不对称性、性双态性和变异性,这可能对外科手术、神经解剖学研究和临床评估产生影响。该研究揭示了两性颅窝形态和重要手术标志的侧面差异和相关性。

期刊介绍: Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
