A tracheostomy usually takes 20 to 45 minutes to perform. The surgeon or other health care professional will make a cut through the lower front part of your neck and then cut into your windpipe. Cuffed trach tubes may be used. These tubes use air to widen or narrow the tube to fit the hole.
Myringotomy (from Latin myringa eardrum) is a surgical procedure in which a tiny incision is created in the eardrum to relieve pressure caused by excessive buildup of fluid, or to drain pus from the middle ear.epending on the type, the tube is either naturally extruded in 6 to 12 months or removed during a minor procedure. Those requiring myringotomy usually have an obstructed or dysfunctional eustachian tube that is unable to perform drainage or ventilation in its usual fashion.
