Q. WHAT ARE THE FEATURES OF RETRACTED TM?
STAGE I: Pars flaccida is dimpled and more retracted than the normal but not adhered to the malleus.
STAGE II: The retraction pocket is adherent to the handle of malleus and the full extension of the retraction pocket can be seen clearly.
STAGE III: The full extent of retraction pocket is not seen and there is an erosion of the outer attic wall (scutum)
STAGE IV: There is definite erosion of the outer attic wall and the extent of the retraction pocket cannot be seen clearly as most of it are hidden from the view.
STAGE V: Attic cholesteatoma (poulsen)
STAGE I: cholesteatoma limited to one quadrant
STAGE II: Involving multiple quadrant without ossicular involvement
STAGE III: Ossicular involvement without Mastoid extension
STAGE IV: Mastoid involvement ( It carries 67% risk of residual cholesteatoma)
TYPE I: Involvement of mesotympanum without involvement of Incus or stapes.
TYPE II: Involvement of mesotympanum, attic along with erosion of ossicles without extension into mastoid cavity.
TYPE III: Involvement of mesotympanum and mastoid extension.
