摘要:
目的：比较两种原态原位听小骨标本制作方法的优缺点。方法：对4例前下壁入路及40例鼓室盖入路的两种原态原位听小骨制作方法进行探讨和比较。结果：两种方法从不同的角度显示出完整的听骨链及其在鼓室中的相对空间位置：经前下壁入路易操作，但破坏周围结构较多，且砧骨体与砧骨短突暴露不充分；由鼓室盖入路，听骨链暴露充分，但完整性更易于受到损害。结论：就显示听骨链的完整和充分性且保留周围结构而言，由鼓室盖入路较好；就操作简单易行而言，由前下壁入路较优。
Objective: This study aimed to investigate the advantages and disadvantages between two methods of fabricating ossicles specimen. Methods: Two kinds of fabricating ossicles methods, including 4 cases of anterior inferior approach and 40 cases of tympanic approach, were compared. Results: The experiment showed that the whole auditory ossicles can be displayed from different angles and the relative spatial position in tympanic cavity can be observed by both methods. The first method is easier to operate but will damage more tissues, and the incus body and the dump of incus are exposed incompletely. In the later way auditory ossicles are exposed completely, but are susceptible to break the auditory ossicles. Conclusions: It is better to adopt the method via the roof of tympanum to display the whole auditory ossicles. To operate easily, it is better to choose the way via the relatively protuberant area of the anterior and inferior wall.
