A mastoidectomy is a procedure performed to remove the mastoid air cells [1] near the middle ear. The procedure is part of the treatment for mastoiditis, chronic suppurative otitis media or cholesteatoma. [2] Additionally, it is sometimes performed as part of other procedures, such as cochlear implants, [3] or to access the middle ear.
A graft may be taken to reconstruct the tympanic membrane. Common graft sites include the temporalis fascia and the tragus. The surgery takes 1 ⁄ 2 to 1 hour if done through the ear canal and 1 + 1 ⁄ 2 to 2 hours if an incision is needed. It is done under local or general anesthesia. It is done on an inpatient or day case basis and is ...

The tube is extruded spontaneously after a few weeks to months, and the incision heals naturally. If there are complications, or the mastoiditis does not respond to the above treatments, it may be necessary to perform a mastoidectomy: a procedure in which a portion of the bone is removed and the infection drained.

Cholesteatoma is a destructive and expanding growth consisting of keratinizing squamous epithelium in the middle ear and/or mastoid process. [1] [2] Cholesteatomas are not cancerous as the name may suggest, but can cause significant problems because of their erosive and expansile properties.
The tympanic antrum is bounded above by a thin plate of bone, the tegmen tympani, which separates it from the middle fossa of the base of the skull, below by the mastoid process, laterally by the squama just below the temporal line, and medially by the lateral semicircular canal of the internal ear, which projects into its cavity.
A hunter missed the mark almost 14,000 years ago, but their bad luck left a valuable discovery stuck in the skeleton of their ancient prey. Dubbed the “Manis projectile point,” the ancient ...
A myringotomy is a surgical procedure in which an incision is created in the eardrum (tympanic membrane) to relieve pressure caused by excessive buildup of fluid, or to drain pus from the middle ear. A tympanostomy tube may be inserted through the eardrum to keep the middle ear aerated for a prolonged time and to prevent reaccumulation of fluid ...
