Pars Tensa Retractions

 

In the same way that the pars flaccida is vulnerable to retraction, the pars tensa may also become retracted.  This usually occurs at the posterosuperior section of the pars tensa, where it may involve the long process of the incus, stapes and other middle ear structures.
