Types of ENT Surgeries performed : E A R

1. Myringotomy: Myringotomy is a surgical procedure in which a tiny incision is created in the eardrum, so as to relieve pressure caused by the excessive buildup of fluid, or to drain pus. Myringotomy is often performed as a treatment for otitis media. Myringotomy with tube insertion is performed for the relief of otitis media. Although this very brief microsurgical procedure can be performed on an outpatient basis, without the need for a general anaesthetic in co-operative adults, children require a short general anesthetic for tube insertion.

2. Tympanoplasties: It is a surgical correction or repair of defects or injuries in the eardrum or the bones of the middle ear. In most cases, the operation relieves pain and infection symptoms completely. Hearing loss is minor. The outcome may not be as good if the bones in the middle ear need reconstruction along with the eardrum.

3. Stapedectomy: A stapedectomy is a surgical procedure of the middle ear performed to improve hearing. If the stapes footplate is fixed in position, rather than being normally mobile, then a conductive hearing loss results. The results of this surgery are generally most reliable in patients' whose stapes has lost mobility because of otosclerosis. Nine out of ten patients who undergo the procedure will come out with significantly improved hearing.

4. Mastoidectomy: Mastoidectomy is an operation to remove disease from the bone behind the ear, when medical management is inadequate. There need not be drainage or ear pain for mastoid disease to exist. Sometimes a mastoidectomy is required in order to gain better exposure to the middle ear and attic.

5. Sac Decompression

6. Facial Nerve: The facial nerve extends from the base of the skull, winds around the ear, passes through the salivary gland, and divides into many branches that connect to various facial muscles, the tear gland, and the tongue. Sometimes the facial nerve becomes compressed, usually behind the ear, due to inflammation from a viral infection, tumors, or injury. If the nerve sustains damage as a result of such compression, symptoms including facial weakness, paralysis, spasms, and twitching can manifest. Other consequences may include inability to properly close the eye, excessive tearing, drooling, and inability to taste certain foods. Different procedures may be performed depending on the cause of compression, location of damage, and other factors.

7. Cochlear Implant:

A cochlear implant (CI) is a surgically implanted electronic device that provides a sense of sound to a person who is profoundly deaf or severely hard of hearing. The cochlear implant is often referred to as a bionic ear. Unlike hearing aids, the cochlear implant does not amplify sound, but works by directly stimulating any functioning auditory nerves inside the cochlea with electrical impulses. External components of the cochlear implant include a microphone, speech processor and transmitter.
Under the appropriate conditions, an implant can give a deaf person a useful auditory understanding of the environment and/or hearing and help them to understand speech, although post-implantation therapy is usually required.

8. Orbital decompression: Orbital decompression surgery is a procedure that may be necessary for patients with visual loss due to compromise of optic nerve function or for patients whose Grave’s disease has caused significant disfigurement. In orbital decompression, the surgeon creates fractures of the thin bones of the orbital walls, allowing the orbital contents to be displaced into the sinuses. This permits a significant diminution of proptosis, i.e., the bulging eyes fall backward into the orbit creating a more natural appearance.
