The foramen tympanicum is located on the anteroinferior region of the external acoustic meatus and posteromedial to the temporomandibular joint in children between the 1st and the 5th year of life. It is considered an anatomical variation when it persists in adults. The aim of this study was to verify the prevalence as well as to characterise the foramen tympanicum in computed tomography (CT) scans of the population from southeastern part of Brazil.
