High-resolution computed tomography scanning (CT) allows depiction of microanatomic structures of the temporal bone. CT is useful for detecting several pathologic conditions of the temporal bone such as congenital malformations, particularly in young children with sensorineural hearing loss. Some external, middle and inner ear structures are difficult to evaluate. The objective of this study has been to provide the key planes in coronal and axial planes (five coronal planes and three axial planes) but also with oblique planes reconstruction (two planes) for normal temporal bones evaluation. These standardized planes help to improve visualization of the main congenital malformations. Identification of obvious morphogenetic malformations (Michel aplasia, Mondini deformity….) is not difficult. However, less severe dysplasia may be missed or normal micro anatomic structures in newborn misreaded.
高分辨率计算机断层扫描（CT）能够显示颞骨的微观解剖结构。CT对于检测颞骨的多种病理状况很有用，比如先天性畸形，尤其是对于患有感音神经性听力损失的幼儿。一些外耳、中耳和内耳结构难以评估。本研究的目的是提供冠状面和轴位面（五个冠状面和三个轴位面）的关键平面，同时还包括用于正常颞骨评估的斜平面重建（两个平面）。这些标准化平面有助于改善主要先天性畸形的可视化。识别明显的形态发生畸形（米歇尔发育不全、蒙迪尼畸形……）并不困难。然而，不太严重的发育异常可能会被遗漏，或者新生儿正常的微观解剖结构会被误读。
