Mastoid surgery

Failure of the surgery to fix the ear drum, remove all infection or cyst can occur. Pain, infection and bleeding are complications of any surgical procedure. These are fortunately rare in ear surgery. Blood loss after tympanoplasty surgery is usually too small to measure. The ear is numbed with long lasting drugs that generally keep the patient comfortable for many hours. Most patients use Tylenol or Motrin/Advil for pain. Narcotics are occasionally used. Infection after ear surgery is very rare. Antibiotics are used for 1 week after medial and lateral tympanoplasty.

Q. What types of gastric bypass surgeries are there? I heard all sorts of options for gastric bypass are available. What is the most in use? A. Bariatric surgeries or – gastric bypass surgeries for weight loss fall into three categories: Restrictive procedures make the stomach smaller to limit the amount of food intake, malabsorptive techniques reduce the amount of intestine that comes in contact with food so that the body absorbs fewer calories, and combination operations employ both restriction and malabsorption. The exact one to be done should be decided with the physician according to each patients abilities and pre-operative function level.

Risks of the surgery are the same as if the cholesteatoma is not removed, but occur less frequently.  Hearing loss and dizziness may occur along with injury to the lining or dura of the brain.  The VII Nerve runs through the center of the middle ear and mastoid cavity and can be injured during surgery.  This may cause a facial paralysis.  However, from the picture on the right, one can see how this nerve can be easily damaged by the cholesteatoma .  Thus, once diagnosed, most cholesteatoma should be surgically removed.  Kos et al. reported on the results for canal wall down mastoidectomies .  He found the average pre-operative hearing loss was 52 dB.  Post-operatively the hearing was unchanged in 41%, improved in 31% and worse in 28%.  Other complications were persistent vertigo and one case of facial paralysis.  View Abstract

A long standing cholesteatoma can erode through the dura and into the brain or into the inner ear.  The horizontal semicircular canal is the inner ear structure most prone to damage.  Below is a link to a CT Scan of a cholesteatoma which produced a fistula of the horizontal semicircular canal.  The patient had a chronic history of hearing loss and ear drainage.  He recently, experienced a severe episode of vertigo from labyrinthitis .
