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.
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 ...
Interventional MRI can be used for a variety of specialized procedures. iMRI systems are often used for doing biopsies of lesions, resections of tumors, guiding thermal ablation of tissue, as well as other procedures. It is commonly used in neurosurgery, where every millimeter of tissue spared in surgery can make a difference for patient recovery.
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"
Part of the wider field of computer-assisted surgery, image-guided surgery can take place in hybrid operating rooms using intraoperative imaging. A hybrid operating room is a surgical theatre that is equipped with advanced medical imaging devices such as fixed C-Arms, CT scanners or MRI scanners.
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 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.
The patient could irreversibly decompensate from some undetected acute condition before the surgery could be initiated and completed, or the surgery might reveal no significant abnormalities. [2] In a high percentage of cases, exploratory surgery was unable to provide a definitive answer, meaning the patient had endured great suffering for no ...
