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 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 ...
In veterinary medicine, this is a common procedure to “treat centrally located intervertebral disc herniation”. [8] Veterinary surgeons use the ventral slot technique when the animal shows symptoms of pain and or sensorimotor deficits belonging either to compression of the spinal cord or a single nerve root.
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.
Surgery for cholesteatoma offers the most advantages for using the endoscope instead of the microscope. Failures in cholesteatoma surgery are most common in certain areas of the anatomy of the tympanic cavity, such as the facial recess, sinus tympani, anterior attic, and the protympanum which are poorly accessed with the microscope.

If the sound is more intense than 184 dB, the eardrum is ruptured. 184 dB and above usually comes from military sound exposures, such as with the explosion of an IED (improvised explosive device). When a person has a shock wave, not only is the eardrum ruptured, but also has ossicular discontinuities. The explosion or blast if powerful can ...
Oral anti-pseudomonal antibiotics can be used in case of severe soft tissue swelling extending into the face and neck and may hasten recovery. [citation needed] Although the acute external otitis generally resolves in a few days with topical washes and antibiotics, complete return of hearing and cerumen gland function may take a few more days.
