The tympanic cavity is a small cavity surrounding the bones of the middle ear.

It is formed from the tubotympanic recess, an expansion of the first pharyngeal pouch.

On its lateral surface, it abuts the external auditory meatus from which it is separated by the tympanic membrane (eardrum).

Clinical significance[edit]

If damaged, the tympanic membrane can be repaired in a procedure called tympanoplasty.

Should fluid accumulate within the middle ear as the result of infection or for some other reason, it can be drained by puncturing the tympanic membrane with a large bore needle (tympanocentesis).

Vestibular schwannoma: unusual recurrence presenting as an external auditory canal mass.

Carreño M, Llorente JL, Suárez C.AbstractVestibular schwannomas (VS) commonly are limited to the internal auditory canal (IAC) and cerebellopontine angle. Extension to labyrinth is less frequent, and involvement of the middle ear or external acoustic canal (EAC) is very rare. In this report we present the case of a 41-year-old woman with a VS, which recurred after a previous surgical removal 4 years before. The tumor involved the IAC, cochlea, vestibule, semicircular canals, cavum tympani, mastoid cells, and EAC. Total removal of the tumor was achieved by a transotic approach, without neurological sequela.
