Stapedectomy is a surgical procedure in which the stapes bone is removed from the middle ear and replaced with a prosthesis. If the stapes footplate is fixed in position, rather than being normally mobile, the result is a conductive hearing loss. There are two major causes of stapes fixation.
bi- : two, from the Latin prefix *bi, meaning "two". colono- : related to large intestine colon, from the latin cōlon, "clause [of a poem]", itself from the Greek κωλον, cōlon, "clause, member, part" colpo- : related to the vagina, from the Ancient Greek κόλπος, cólpos, meaning "hollow space", but also a synonym for "womb"
Otology also includes surgical treatment of conductive hearing loss, such as stapedectomy surgery for otosclerosis. Neurotology (a related field of medicine and subspecialty of otolaryngology ) is the study of diseases of the inner ear, which can lead to hearing and balance disorders.
The tympanic membrane is repaired and directly connected to the head of the stapes. Type 4 describes a repair when the stapes foot plate is movable, but the crura are missing. The resulting middle ear will only consist of the Eustachian tube and hypotympanum. Type 5 is a repair involving a fixed stapes footplate. Also called fenestration operation.
In medicine, an ossicular replacement prosthesis is a device intended to be implanted for the functional reconstruction of segments of the ossicles and facilitates the conduction of sound waves from the tympanic membrane to the inner ear. [1]
The stapesplasty prosthesis is indicated in cases of congenital or acquired defects of the stapes due to e.g.: Otosclerosis; Congenital fixation of the stapes; Traumatic injury; Malformation of the ossicular chain/middle ear; It can also be used to treat patients with inadequate conductive hearing from previous stapes surgery.
The stapes or stirrup is a bone in the middle ear of humans and other tetrapods which is involved in the conduction of sound vibrations to the inner ear. This bone is connected to the oval window by its annular ligament , which allows the footplate (or base) to transmit sound energy through the oval window into the inner ear.
Intraoperative magnetic resonance imaging (iMRI) is an operating room configuration that enables surgeons to image the patient via an MRI scanner while the patient is undergoing surgery, particularly brain surgery. iMRI reduces the risk of damaging critical parts of the brain and helps confirm that the surgery was successful or if additional resection is needed before the patient's head is ...
