The goal of treatment is to protect the ear from further damage. [9] Below are possible preventive measures and treatment methods that could help in cases of acoustic trauma Hyperbaric Oxygen therapy: Only when the case is extremely serious. [3] Corticosteroids drugs: anti-inflammatory drug. [3] Eardrum repair [9]
A perforated eardrum (tympanic membrane perforation) is a prick in the eardrum. It can be caused by infection (otitis media), trauma, overpressure (loud noise), inappropriate ear clearing, and changes in middle ear pressure. An otoscope can be used to view the eardrum to diagnose a perforation. Perforations may heal naturally or require surgery.
A myringotomy is a surgical procedure in which an incision is created in the eardrum (tympanic membrane) to relieve pressure caused by excessive buildup of fluid, or to drain pus from the middle ear. A tympanostomy tube may be inserted through the eardrum to keep the middle ear aerated for a prolonged time and to prevent reaccumulation of fluid ...
Tympanic membrane retraction describes a condition in which a part of the eardrum lies deeper within the ear than its normal position. The eardrum comprises two parts: the pars tensa, which is the main part of the eardrum, and the pars flaccida, which is a smaller part of the eardrum located above the pars tensa. Either or both of these parts ...
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
In some cases, proliferating supporting cells directly transdifferentiate into new hair cells, resulting in hearing recovery. [15] Direct transdifferentiation is when neighboring supporting cells convert into hair cells without cell division. Inner ear sensory epithelium is highly conserved (conservation genetics) in all vertebrates. [16]
Hemotympanum is often the result of basilar skull fracture. [1] Hemotympanum refers to the presence of blood in the middle ear, which is the area behind the eardrum. In most cases, the blood is trapped behind the eardrum, so no discharge is visible. Treating hemotympanum depends on the underlying cause.
An acoustic signal from a sound source, such as a radio, enters into the external auditory canal (ear canal), and is funneled through to the tympanic membrane (eardrum), causing it to vibrate. The vibration of the tympanic membrane drives the middle ear ossicles , the malleus, incus, and stapes to vibrate in sync with the eardrum.
