背景和目标。一个有效的耳外科培训计划需要合适的模型来学习特定的准备技术。然而，传统的固定或新鲜冷冻的人尸体的耳朵不能满足所有的要求。因此，我们调查的可行性固定的耳朵根据Thiel的外科培训在颞骨实验室。在根据Thiel固定的尸体耳上评价了外耳和中耳的各种手术技术。组织的结构和一致性进行了比较的重要条件下，通过一个标准化的解剖。耳道、鼓室和乳突组织的结构和一致性与生命状况相当。仅耳廓软骨明显软化，这使手术准备接近活体情况。结论。在中耳外科继续医学教育的质量保证和效率方面，Thiel固定技术提供了一个极好的先决条件。
Background and objective. An efficient training program in ear surgery needs suitable models to learn the specific preparation techniques. However, conventionally fixed or fresh frozen ears of human corpses do not meet all demands.Therefore we investigated the feasibility of ears fixed according to Thiel for surgical training in the temporal bone lab.Methods. Various surgical techniques on external and middle ears were evaluated on ears from cadavers fixed according to Thiel. Structure and consistency of the tissues were compared to vital conditions by means of a standardized questionnaire.Results. Structure and consistency of the tissues of the auditory canal,the tympanic cavity and the mastoid were comparable to vital conditions. Merely the cartilage of the auricle was considerable softened.This enabled a surgical preparation under conditions close to the intravital situation.Conclusions. Under the aspects of quality assurance and efficiency of continuous medical education in middle ear surgery, the Thiel fixation technique provides an excellent prerequisite.
