The mention of this feature in the literature is scarce, generating controversy among the anatomists who have described it. The eponymous Huschke, a German anatomist, who has been mentioned as the first to observe it in 1844. However, there is a history that this bone characteristic was previously described by other authors almost 200 years earlier. The current name, tympanic dehiscence, was given in 1878 by Bürkner, being accepted until today. The objective of this article is to carry out a historical analysis of the morphological description of tympanic dehiscence in specialized anatomical literature.
