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]
A middle ear implant is a hearing device that is surgically implanted into the middle ear. They help people with conductive, sensorineural or mixed hearing loss to hear. [1] Middle ear implants work by improving the conduction of sound vibrations from the middle ear to the inner ear. There are two types of middle ear devices: active and passive.
Computerised tomography (CT) can be used to determine if disease is present in the middle ear. [12] Whilst hearing loss is a common symptom in many diseases of the ear, for example in otosclerosis (abnormal bone growth in the ear), [ 3 ] the white, chalky patches on the tympanic membrane are fairly characteristic of tympanosclerosis.
Low-dose high-resolution (1.25 mm) chest CT. HRCT is performed using a conventional CT scanner. However, imaging parameters are chosen so as to maximize spatial resolution: [1] a narrow slice width is used (usually 1–2 mm), a high spatial resolution image reconstruction algorithm is used, field of view is minimized, so as to minimize the size of each pixel, and other scan factors (e.g. focal ...
The middle ear is the portion of the ear medial to the eardrum, and distal to the oval window of the cochlea (of the inner ear). The mammalian middle ear contains three ossicles (malleus, incus, and stapes), which transfer the vibrations of the eardrum into waves in the fluid and membranes of the inner ear .
Ear clearing – Equalising of pressure in the middle ears; Politzerization – Procedure to inflate the middle ear while swallowing; Müller's maneuver – Procedure used in medicine to diagnose some types of tinnitus; Vagal maneuver – Action used to slow down the heart rate by stimulating the vagus nerve
[citation needed] The roof is formed by the tegmen antri which is a continuation of the tegmen tympani and separates it from the middle cranial fossa. The lateral wall of the antrum is formed by a plate of bone which is an average of 1.5 cm in adults. The mastoid air cell system is a major contributor to middle ear inflammatory diseases. [1]
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.
