Description: Austin - Kartush classification of ossicular chain defect
To predict reconstructive success, the status of the middle ear and ossicular chain needs to be assessed.
The Austin - Kartush classification of ossicular chain defects provides a method for defining pre-reconstructive ossicular status.
Austin's original classification had four groups:-
Malleus handle and stapes suprastructure present
Malleus handle present, stapes suprastructure absent
Malleus handle absent, stapes suprastructure present

Kartush modified this scheme by adding three classes:-
