What is true in case of perforation of pars flaccida -

Tympanic membrane can be divided in 2 parts: Parstensa : It forms most of the tympanic membrane. Its periphery is thickened to form fibro cartilaginous ring called as annulus tympanicus. Pars Falccida : It is situated above the lateral process of malleus between the notch of Rivinus and the anterior and posterior malleolar fold. Ref. Dhingra 6/e p59, 5/e p 78
