In the middle of the nineteenth century the British otologists James Yearsley and Joseph Toynbee each developed their own form of artificial eardrum. Despite initial enthusiasm for these devices, experience amongst the medical profession over the following half century demonstrated their minimal value in the treatment of a perforated eardrum ...
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 ...
used to cut the ear drum: Grommet stapedectomy set: used in surgeries of the ear drum: Tracheostomy tube: used in tracheostomy to bypass the airway above its point of insertion, due to any reason •Fuller's bi-valve type: metal double tube; used in a new tracheostomy or during closing it for a few days •Portex type: used in permanent ...
Tympanoplasty is the general name of the operation to repair the middle ear's eardrum and ossicles. Grafts from muscle fascia are ordinarily used to rebuild an intact eardrum. Sometimes artificial ear bones are placed to substitute for damaged ones, or a disrupted ossicular chain is rebuilt in order to conduct sound effectively.

In the anatomy of humans and various other tetrapods, the eardrum, also called the tympanic membrane or myringa, is a thin, cone-shaped membrane that separates the external ear from the middle ear. Its function is to transmit changes in pressure of sound from the air to the ossicles inside the middle ear, and thence to the oval window in the ...
