Myringoplasty perforation and a small part should also extend over the posterior canal wall. The tympanomeatal flap is then replaced. The temporal fascia is harvested. An incision is made to raise medial meatal skin with tympanic membrane epithelium. The graft is placed on the outer surface of the tympanic membrane and a slit is made to tuck it under the handle of malleus. The ear is packed with gelfoam and antibiotics, and the incision is closed. Finally mastoid dressing is performed. Myringoplasty Myringoplasty is the closure of the perforation of pars tensa of the tympanic membrane. When myringoplasty is combined with
Plasma membrane Ca2+ ATPase to involve the lymph nodes, and are more common among young women, which could help explain their worse prognosis compared with postmenopausal women. PMCAs were first discovered in the 1960s in the membranes of red blood cells. The presence of an ATPase was discovered in the membranes in 1961, and then in 1966 it was discovered that these ATPases pump Ca out of the cytosol. PMCA was first purified from red blood cell membranes in 1979. Plasma membrane Ca2+ ATPase The plasma membrane Ca ATPase (PMCA) is a transport protein in the plasma membrane of cells and functions to remove
