摘要

目的：我们的目的是分析儿童和成人内耳道（IAC）形态的发育变化，以获得三维认识，从而改进各种手术方法：我们利用正常颞骨 CT 扫描的三维重建数据，对 60 名患者的 120 只耳朵进行了回顾性研究，患者年龄从出生到成年不等。我们使用 Vworks 4.0 版（CyberMed，韩国首尔）对颞骨中 IAC 的体积进行了三维重建。数据按年龄组进行分类和评估。使用 CT 扫描的轴向、冠状和矢状切面测量三维对象中的 IAC 参数：结果：从第 1 组到第 2 组，随着年龄的增长，IAC 体积明显增大（P = 0.01）。IAC 体积与研究参数也有明显相关性（P = 0.001）。IAC 体积与六个参数之间的 Spearman's rho 值如下：Wp（r = 0.619）、Wv（r = 0.763）、Wm（r = 0.697）、Dp（r = 0.541）、Dm（r = 0.692）和 Lpf（r = 0.659）：结论：IAC 的体积在青春期持续增长。了解 IAC 的正常生长模式和三维形态有助于采用不同的手术方法。

Morphometric analysis of the internal auditory canal by developmental change using three-dimensional computed tomography.

Purpose: Our aim was to analyze the developmental changes in the morphology of the internal auditory canal (IAC) in both children and adults to gain a three-dimensional understanding that could enhance various surgical approaches.

Methods: We retrospectively investigated 120 ears of 60 patients, ranging in age from birth to adulthood, using 3D-reconstruction data from normal temporal bone CT scans. The volume of the IAC in the temporal bone was reconstructed in 3D using Vworks version 4.0 (CyberMed, Seoul, Republic of Korea). Data were classified and evaluated by age group. IAC parameters were measured in the 3D objects using the axial, coronal, and sagittal sections of the CT scans.

Results: The IAC volume significantly increased with aging from group 1 to group 2 (P = 0.01). The IAC volume also significantly correlated with the studied parameters (P = 0.001, for all). The Spearman's rho values between the volume of IAC and the six parameters were as follows: Wp (r = 0.619), Wv (r = 0.763), Wm (r = 0.697), Dp (r = 0.541), Dm (r = 0.692), and Lpf (r = 0.659).

Conclusions: IAC volume continues to develop through adolescence. Understanding the normal growth pattern and three-dimensional morphology of the IAC would be helpful for different surgical approaches.

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.
