The foramen of Huschke is a dehiscence in the antero‐inferior surface of the tympanic plate, which forms during the normal post‐natal development of the temporal bone. Closure of the foramen is generally reported to take place by 5 years of age, although a persistent foramen has been observed in 0–67% of adult crania depending on the population. A persistent foramen of Huschke in adult life may be involved in abnormalities of the external auditory canal and related structures, which can lead to otological complications. This paper examines age‐related changes in the development of the tympanic plate from the perinatal to the adult condition using two osteological samples from Britain, and is the first systematic evaluation beyond the age of six years. The results suggest that the widely cited chronology for the closure of the foramen of Huschke is erroneous. Earlier stages of formation may be used for narrowing age estimation in fragmentary remains of juveniles in a skeletal collection of unknown age or in a forensic or clinical context.
