Abutment
Mastoidectomy
An injury or infection that can
damage themalleus, incus, or
stapesbone.
Ossicle
Damage
Damaged
incus
An abnormalgrowthofboneof the inner
ear involving the stapes and cochlea.
Otosclerosisprevents the stapes from
movingproperly and causeshearing
loss. It can also cause a sensorineural
hearing losswhen it involves the cochlea.
