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 ...
Tympanoplasty can be performed through the ear canal (transcanal approach), through an incision in the ear (endaural approach) or through an incision behind the ear (postauricular approach). A graft may be taken to reconstruct the tympanic membrane.
A TTS will resolve with time, while the time frame for hearing recovery is unique in every case, any SNHL that persists beyond eight weeks after injury is most likely permanent and should be considered PTS. [4] Hearing loss; Tinnitus (ringing in the ear) Aural fullness (ear fullness) Recruitment (ear pain with loud noise) Difficulty localizing ...
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 ...
There are two types of PMEIs: tympanoplasty implants and stapes implants. Tympanoplasty implants (also known as PORPs or TORPs) are suitable for patients with a mobile stapes footplate, ie. a stapes footplate that moves in the normal way. Either a partial or a total tympanoplasty implant can be used, depending on the condition of the stapes.
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.
Stapedectomy has success rates ranging from 80% to 95%. [5] [6]Stapedectomy closes what is called the "air bone gap" very efficiently, meaning it restores efficient conduction of sound coming through the air close to the level of the best ability of the nerve cells to perceive the sound.
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.
