The foramen of Huschke: age and gender specific features after childhood

Temporomandibular-External Auditory Canal Fistulas Treatment

“…A persistent communication, however, was found in a recent retrospective review in 12% of men and in 20% of women (P < 0.0001). 9 Anatomically, the EAC and the TMJ are separated by the tympanic plate of the temporal bone. Because of its thinness, however, the tympanic plate is susceptible to fractures when a posterior displacement of condyle occurs.…”

“…Different types of myocutaneous trapezius flaps described in the study include the superior, the lateral island, the vertical, and the lower island flap. [9][10][11][12] This flap is easy to harvest, has a large arc of rotation, is well vascularized, and is more pliable than both lattisimus dorsi and pectoralis major flap. In addition, it can provide bulk to the soft-tissue defect and can be extended with the use of a tissue expander.…”

Foramen of Huschke (tympanicum) in a Nigerian male with articular soft-tissue herniation into the external auditory meatus

“…[1] In asymptomatic population, its prevalence varies from 4.6% to 20% respectively, [1,2] but this has been shown to decrease with age, suggesting that it closes with time. [3] Embryologically, the tympanic bone develops intramembraneously. The foramen of Huschke represents an opening in the developing tympanic ring which is at the floor of the EAM.…”

Foramen tympanicum with symptomatic temporomandibular joint herniation

“…Foramen tympanicum (FT) arises from an incomplete ossification of the tympanic part of the temporal bone that persists after 5 years of age, and is classically located at the ventrocaudal aspect of external acoustic meatus (EAM), posteromedial to the temporomandibular joint (TMJ) [1]. We discuss a case of TMJ herniation through a FT presenting with chronic otorrhea.…”
