Abstract

Purpose: This study investigated the internal carotid artery (ICA) and jugular bulb (JB) structures in terms of lateral temporal bone resection using 3D computed tomography (CT).

Methods: We retrospectively investigated 80 ears of 40 patients using 3D reconstruction data from normal temporal bone CT. Ten critical points (P) in the temporal bone were marked in the 3D object with reference to the axial, coronal, and sagittal images of the CT scans. An imaginary plane of the facial nerve (PLf) course was also reconstructed in relation to the three points of the chorda-facial junction, P5 (second genu), and P3 (cochleariform) process.

Results: The distances (mean ± SD; mm) from points P3 to P1 (the highest level of the JB) and P2 (the posterior wall of the ascending petrous IAC at the level of the Eustachian tube) were 12.03 ± 2.56 and 9.79 ± 1.78, respectively. The distances from point P4 (chorda-facial junction) to P1 and P2 were 10.98 ± 2.70 and 17.66 ± 2.26, respectively. The angles (mean ± SD; degree) between the PLf to the line from Pa (point of the anterior bony canal) to P3 and P4 were 17.80 ± 10.05º and 8.93 ± 5.37º, respectively. The angles between the PLf to the line from P3 to P1 and P2 were - 36.35 ± 13.28º and - 24.78 ± 13.91º, respectively. The angles between the PLf to the line from P4 to P1 and P2 respectively were - 40.35 ± 15.37º and - 13.34 ± 7.63º.

Conclusions: Understanding the anatomical relationships of P1 and P2 at P3 and P4 can be helpful in preventing iatrogenic trauma of the ICA and JB.

使用三维计算机断层扫描对侧颞骨切除术中的颈内动脉和颈静脉球进行放射学评估。

目的：本研究使用三维计算机断层扫描（CT）对侧颞骨切除术中的颈内动脉（ICA）和颈静脉球（JB）结构进行了研究：我们使用正常颞骨 CT 的三维重建数据对 40 名患者的 80 耳进行了回顾性研究。参照 CT 扫描的轴位、冠状位和矢状位图像，在三维对象中标记了颞骨的 10 个临界点 (P)。此外，还重建了面神经（PLf）走向的假想平面，该平面与脐-面交界处、P5（第二膝突）和P3（耳蜗突）这三个点相关：从 P3 点到 P1（JB 的最高水平）和 P2（咽鼓管水平的升瓣 IAC 后壁）的距离（平均值 ± SD；毫米）分别为 12.03 ± 2.56 和 9.79 ± 1.78。从 P4 点（脐面交界处）到 P1 和 P2 的距离分别为 10.98 ± 2.70 和 17.66 ± 2.26。PLf与Pa（前骨管点）至P3和P4的连线之间的角度（平均值±标度；度数）分别为17.80±10.05º和8.93±5.37º。PLf与P3至P1和P2的连线之间的夹角分别为- 36.35 ± 13.28º和- 24.78 ± 13.91º。PLf与 P4 至 P1 和 P2 的连线的夹角分别为 - 40.35 ± 15.37º 和 - 13.34 ± 7.63º：了解 P3 和 P4 处 P1 和 P2 的解剖关系有助于预防 ICA 和 JB 的先天性创伤。

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.
