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 .
The success rate of either surgery depends greatly on the skill and the familiarity with the procedure of the surgeon. [17] However, comparisons have shown stapedotomy to yield results at least as good as stapedectomy, with fewer complications, and thus stapedotomy is preferred in normal circumstances. [30]
Some over-the-counter as well as prescription drugs and certain industrial chemicals are ototoxic. Exposure to these can result in temporary or permanent hearing loss. Some medications cause irreversible damage to the ear, and are limited in their use for this reason. The most important group is the aminoglycosides (main member gentamicin). A ...
Otoplasty (surgery of the ear) was developed in ancient India and is described in the medical compendium, the Sushruta Samhita (Sushruta's Compendium, c. 500 AD).The book discussed otoplastic and other plastic surgery techniques and procedures for correcting, repairing and reconstructing ears, noses, lips, and genitalia that were amputated as criminal, religious, and military punishments.
Hyperacusis is an increased sensitivity to sound and a low tolerance for environmental noise. Definitions of hyperacusis can vary significantly; it often revolves around damage to or dysfunction of the stapes bone, stapedius muscle or tensor tympani ().
If the ear is dry and not infected, an air conduction aid could be tried; if the ear is draining, a direct bone conduction hearing aid is often the best solution. If the conductive part of the hearing loss is more than 30–35 dB , an air conduction device could have problems overcoming this gap.
While men, since the later 1900s and particularly in the ’90s, have had a higher cancer incidence than women, incidence rates in women 50-64 years of age have now surpassed those in men.
The implant then sends sound vibrations to the cochlea of the normal hearing ear through the skull via bone conduction. [11] The ADHEAR bone conduction system is a non-surgical device that sticks to the skin behind the ear. It vibrates to send sound vibrations through the skin and the skull bone to the cochlea of the normal hearing ear. [12]
