Eardrum within two to four weeks. The prognosis becomes more guarded as the force of injury increases. The pressure of fluid in an infected middle ear onto the eardrum may cause it to rupture. Usually this consists of a small hole (perforation), which allows fluid to drain out. If this does not occur naturally, a myringotomy (tympanotomy, tympanostomy) can be performed. A myringotomy 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. The fluid or pus comes from a
Cherney incision Cherney incision The Cherney incision is an incision used in gynecologic surgery. It is similar to the Pfannenstiel incision but allows access to the space of Retzius and gives a larger area in which to operate. The Cherney incision begins when the skin is cut 2-3 centimeters above the pubic symphysis and the surgeon dissects down to the rectus abdominis muscle. The surgeon then uses blunt dissection with the fingers to separate the tendons from the bladder before cutting the tendons 1-2 centimeters above the pubic symphysis. The muscles are then lifted away, toward the patient's head (cephalad). Then, the
