The surgery takes 1 ⁄ 2 to 1 hour if done through the ear canal and 1 + 1 ⁄ 2 to 2 hours if an incision is needed. It is done under local or general anesthesia. It is done on an inpatient or day case basis and is successful 85–90% of the time. [4]
The endoscope allows the surgeon to look around the corners and to reach inaccessible areas like the sinus tympani through the ear canal. [9] Endoscopic ear surgery utilizes the ear canal as the access point for removal of cholesteatoma and therefore represent a minimally invasive alternative to traditional surgery that requires large incision ...
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.
The removal of the ear canal wall results in: a space, the "mastoid cavity", which is less likely than the original ear canal to resist infection; exposure of the ossicles, which may allow the subsequent formation of a new cholesteatoma deep to the ossicles. To prevent this, these ossicles must be removed, which may diminish the patient's hearing.
In this approach, the semicircular canals and vestibule, including the utricle and the saccule of the inner ear are removed, causing complete hearing loss in the operated ear. The procedure is typically performed by a team of surgeons, including a neurotologist (an ear, nose, and throat surgeon specializing in skull base surgery) as well as a ...
The ear is washed and a small incision made in the eardrum. Any fluid that is present is then aspirated, the tube of choice inserted, and the ear packed with cotton to control any slight bleeding that might occur. This is known as conventional (or cold knife) myringotomy and usually heals in one to two days. [13]
This antihelix plastic surgery is performed with the incision-suture technique. A long incision is made on the back of the ear and a strip of skin is removed. The cartilage is completely cut through in several places. With thick cartilage, the back of the antihelix is made thinner by using a scalpel to remove cartilage.
