What is Laser Stapedotomy?
Laser stapedotomy (Stapedectomy) is a surgical procedure to repair conductive loss of hearing caused by otosclerosis. In otosclerosis, the stapes bone becomes rigid and therefore cannot vibrate due to a bone overgrowth surrounding the footplate. This causes gradual hearing loss. Laser stapedotomy helps in the treatment of otosclerosis by bypassing the rigid stapes with a prosthetic piston. Using carbon dioxide lasers during laser stapedotomy enables the creation of tiny and accurately placed holes, without causing temperature increase inside the ear.
How is Laser Stapedotomy performed?
- Using a laser, a hole that is smaller than 0.8mm is created in the footplate.
- Prosthesis is placed by bypassing the rigid stapes.
- A tissue graft seal of the fenestra may also be used to improve this procedure.
- Laser stapedotomy is performed on only one ear at a time. If it is required to be performed on another ear, it can be done one year later.
How to prepare for Laser Stapedotomy?
- Certain medications that increase the risk of bleeding should be avoided for two weeks before laser stapedotomy. This includes herbal and homeopathic medication.
- The patient can take little amounts of water for four hours before the surgery.
Duration of procedure/surgery:Approximately 45 minutes
Days admitted:Laser stapedotomy is usually performed as an outpatient procedure. Occasionally patients may need to stay overnight.
Anesthesia:Local anesthesia
Recovery:- The patient can recover within a few days or weeks after laser stapedotomy.
- A follow-up visit should be scheduled about a week or 10 days after the surgery.
- Several post-operative check-ups are performed over four to six weeks after laser stapedotomy.
Risks:- Bleeding
- Infection
- Loss of hearing
- Vertigo or dizziness
- Perforation of the eardrum
- Tinnitus
- Injury to the facial nerve causing facial paralysis
- Laser fire
After care:- The ear should be kept dry for two to three weeks after laser stapedotomy.
- The patient may take a bath after 24 hours, without letting water inside the ear.
- The patient should avoid any strenuous physical activity after the surgery.
- Blowing the nose should also be avoided.
