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]
Inner ear regeneration is the biological process by which the hair cells and supporting cells (i.e. Hensen's cells and Deiters cells) of the ear proliferate (cell proliferation) and regrow after hair cell injury. This process depends on communication between supporting cells and the brain.
The ear is washed and a small incision made in the eardrum. Any fluid that is present is then aspirated, the tube of choice inserted, and the ear packed with cotton to control any slight bleeding that might occur. This is known as conventional (or cold knife) myringotomy and usually heals in one to two days. [13]
A cochlear implant (CI) is a surgically implanted neuroprosthesis that provides a person who has moderate-to-profound sensorineural hearing loss with sound perception. With the help of therapy, cochlear implants may allow for improved speech understanding in both quiet and noisy environments.
Assessment of transient evoked otoacoustic emissions (TEOAE) in an adult. An otoacoustic emission (OAE) is a sound that is generated from within the inner ear.Having been predicted by Austrian astrophysicist Thomas Gold in 1948, its existence was first demonstrated experimentally by British physicist David Kemp in 1978, [1] and otoacoustic emissions have since been shown to arise through a ...
Sound above a certain decibel level can cause permanent damage to inner ear stereocilia. New research has shown that the damage can possibly be reversed if we can repair or recreate some of the proteins in the stereocilia. In this study, scientists used zebrafish to examine the motion of proteins within live ear cells using a confocal ...
In general, structural damages to any anatomical part of the human ear can cause hearing-related problems. Usually, minor bending of the stereocilia of the inner ear is associated with temporary hearing loss and is involved in auditory fatigue. Complete loss of the stereocilia causes permanent hearing damage and is more associated with noise ...
Sound is transmitted to the inner ear via vibration of the tympanic membrane, leading to movement of the middle ear bones (malleus, incus, and stapes). Movement of the stapes on the oval window generates a pressure wave in the perilymph within the cochlea, causing the basilar membrane to vibrate. Sounds of different frequencies vibrate ...
