Myringotomy & ear tubes

Myringotomy and ear tubes placement is the most frequently performed ear operation. It involves making a cut in the ear drum and placing a pressure equalizing tube, which remains in place for 6-12 months. This procedure is performed under local anesthesia in adults and under general anesthesia in children.

Tympanoplasty

Tympanoplasty is a surgical procedure performed to close a perforation in the ear drum. A perforation in the ear drum can result in frequent ear infections and conductive hearing loss. This is an outpatient procedure performed under general anesthesia.

Stapedectomy

Otosclerosis is a condition of abnormal growth in the middle ear, which leads to fixation of the stapes bone. This prevents stapes bone from transmitting the sound into the inner ear, causing conductive hearing loss. Stapedectomy is a surgical procedure which involves removing immobilized stapes bone and replacing it with a prosthesis. The surgery is performed under general anesthesia through the ear canal.

Mastoidectomy

Located behind the ear, the mastoid bone contains many air-filled spaces when healthy. Infection or disease in the ear such as cholesteatoma (an abnormal growth of skin cells behind the ear drum that may cause hearing damage) can cause those spaces to fill with fluid, mucus or excess tissue.

When medications fail to resolve the problem, a mastoidectomy to remove mastoid infection or cholesteatoma may be performed.

Cochlear implants

A cochlear implant is an electronic device that restores partial hearing to individuals with severe to profound hearing loss. It is surgically implanted into the inner ear and is activated by a device worn outside the ear. Cochlear implants are not hearing aids – they do not amplify sound the ear already hears. Instead, the device bypasses the damaged parts of the auditory system and stimulates the hearing nerve. This allows severely hearing-impaired individuals who can not hear with a conventional hearing aid to understand sounds in their environment, such as speech.
