This surgery involves removal and replacement of a part of a bone in the ear.
This surgery is performed in individuals suffering from otosclerosis. The exact cause of the disease is not known but it is believed to run in families. Here, a tiny bone in the ear called the stapes is fixed due to extra growth and thus results in hearing loss. More often both ears will be involved. The diagnosis is made using otoscopic ear examination and audiometric tests but the disease can only be confirmed on operation table after the ear is examined.
The surgery is performed usually under local anaesthesia to check hearing improvement after the surgery but can also be performed under general anaesthesia.
A small cut is given inside the ear canal and the ear drum is lifted. The middle ear bones are examined and checked if there is fixation of the stapes bone. Part of the bone is removed and a artificial bone (piston) is placed in its position. The hearing improvement is tested on table. The cut is stitched and ear pack is placed.
Patient is discharged same day or next day and asked to come back for pack removal after a week. Meanwhile patient is advised to use ear drops and and avoid any strenuous activities.
Only one ear will be operated at a time and if problem persists in the other ear, patient is called back after a few months.
Patient may experience Giddiness, noise in the ear and altered taste sensation for a few months following surgery. Hearing improvement can be noted only after two to three weeks after surgery by the patient due to presence of medicine and pack in the ear.
