Epitympanic recess, the Glossary
The epitympanic recess is the portion of the tympanic cavity (of the middle ear) situated superior to the tympanic membrane. The recess lodges the head of malleus, and the body of incus. The mastoid antrum is situated posterior to the recess and opens into the recess at the posterior wall of the recess via the aditus to mastoid antrum.[1]

Aditus to mastoid antrum
The aditus to mastoid antrum (otomastoid foramen) is a large, irregular opening upon the posterior wall of the tympanic cavity by which the mastoid antrum (situated posteriorly) communicates with the epitympanic recess of the tympanic cavity (situated anteriorly). Epitympanic recess and aditus to mastoid antrum are anatomy stubs.

Antibiotic
An antibiotic is a type of antimicrobial substance active against bacteria.
See Epitympanic recess and Antibiotic
Eardrum
In the anatomy of humans and various other tetrapods, the eardrum, also called the tympanic membrane or myringa, is a thin, cone-shaped membrane that separates the external ear from the middle ear. Epitympanic recess and eardrum are Otology and Otorhinolaryngology.
See Epitympanic recess and Eardrum
Incus
The incus (incudes) or anvil in the ear is one of three small bones (ossicles) in the middle ear. Epitympanic recess and incus are Otology and Otorhinolaryngology.
See Epitympanic recess and Incus
Inflammation
Inflammation (from inflammatio) is part of the biological response of body tissues to harmful stimuli, such as pathogens, damaged cells, or irritants.
See Epitympanic recess and Inflammation
Malleus
The malleus, or hammer, is a hammer-shaped small bone or ossicle of the middle ear. Epitympanic recess and malleus are Otology and Otorhinolaryngology.
See Epitympanic recess and Malleus
Mastoid antrum
The mastoid antrum (tympanic antrum, antrum mastoideum, Valsalva's antrum) is an air space in the petrous portion of the temporal bone, communicating posteriorly with the mastoid cells and anteriorly with the epitympanic recess of the middle ear via the aditus to mastoid antrum (entrance to the mastoid antrum). Epitympanic recess and mastoid antrum are human head and neck, Otology, Otorhinolaryngology and skull.
See Epitympanic recess and Mastoid antrum
Mastoid cells
The mastoid cells (also called air cells of Lenoir or mastoid cells of Lenoir) are air-filled cavities within the mastoid process of the temporal bone of the cranium. Epitympanic recess and mastoid cells are human head and neck, Otology, Otorhinolaryngology and skull.
See Epitympanic recess and Mastoid cells
Mastoid part of the temporal bone
The mastoid part of the temporal bone is the posterior (back) part of the temporal bone, one of the bones of the skull. Epitympanic recess and mastoid part of the temporal bone are human head and neck, Otology, Otorhinolaryngology and skull.
See Epitympanic recess and Mastoid part of the temporal bone
Mastoidectomy
A mastoidectomy is a procedure performed to remove the mastoid air cells, air bubbles in the skull, near the middle ear. Epitympanic recess and mastoidectomy are human head and neck, Otology, Otorhinolaryngology and skull.
See Epitympanic recess and Mastoidectomy
Semicircular canals
The semicircular canals are three semicircular interconnected tubes located in the innermost part of each ear, the inner ear. Epitympanic recess and semicircular canals are human head and neck, Otology and Otorhinolaryngology.
See Epitympanic recess and Semicircular canals
Tympanic cavity
The tympanic cavity is a small cavity surrounding the bones of the middle ear. Epitympanic recess and tympanic cavity are human head and neck, Otology and Otorhinolaryngology.
