The study of the topographical and three dimensional anatomy of the human external auditory canal and tympanic membrane has been simplified by applying a dental impression technique to the cadaver ear. A light silicone resin was catalyzed and syringed into the anterior recess and then into the entire external canal. Analysis of these impressions showed them to compare well with earlier morphological techniques, and to provide a durable and reliable replica of the surface of the tympanic membrane, the interior of the external auditory canal, and the lateral surface of the pinna. The resulting impressions displayed the anatomical features of the external auditory canal in a unique three-dimensional fashion which was also suitable for measurement of the anatomical features of the canal.
通过将牙科印模技术应用于尸体耳朵，人类外耳道和鼓膜的局部解剖学及三维解剖学研究得以简化。将一种轻质硅树脂催化后，用注射器注入前隐窝，然后注入整个外耳道。对这些印模的分析表明，它们与早期的形态学技术相比效果良好，并且能提供鼓膜表面、外耳道内部以及耳廓外侧表面的持久且可靠的复制品。所得印模以独特的三维方式展示了外耳道的解剖特征，这也适用于测量外耳道的解剖特征。
