A knowledge of the external ear and tympanic membrane is essential to practicing audiologists. This article provides an introduction to the anatomy of this area including dimensions, orientation, vasculature, innervation, and relations to other structures. Traditional diagrams are often inadequate in describing these structures. For example, typical frontal and sagittal views of the external auditory meatus do not adequately describe its anteroposterior course. Axial (transverse) views provide easier visualization of these areas. A nomenclature is also provided for areas and angles of the external auditory meatus.
对于执业听力学家而言，了解外耳和鼓膜至关重要。本文介绍了该区域的解剖结构，包括尺寸、方位、血管、神经支配以及与其他结构的关系。传统的图表往往不足以描述这些结构。例如，外耳道的典型正面和矢状面视图无法充分描述其前后走向。轴向（横向）视图能更清晰地显示这些区域。本文还对外耳道的区域和角度给出了命名法。
