To allow a better ET exposure, the facial recess is first opened, the incudostapedial and incudomalleolar
joints are disarticulated, and the incus is removed.
They could identify several key structures such as incudomalleolar
articulation, tympanic segment of the facial nerve, lateral semicircular canal and aditus ad antrum, all without provoking lesions in the middle ear structures.
This condition includes: synovial destruction of the incudostapedial (Incus, see diagram) and incudomalleolar
(Malleus, see diagram) joints, which help transmit vibrations in the inner ear that are perceived as sound; these, like other joints in the body, can be affected by RA.
Then the posterior ear canal wall was worn thin to gradually open the attic forward and to expose the incudomalleolar
Disarticulation of the incudostapedial joint and/or incudomalleolar
joint may occur, so it is extremely important to carefully examine both joints in order to achieve the best potential outcome for hearing.
Posterior growth may extend further, involving the incudostapedial joint and the stapes suprastructure, as well as up towards the incudomalleolar
joint, around the incus, and into the attic.
the incudomalleolar joint) in a 64-year-old woman, and we describe the clinical, radiologic, and intraoperative findings in this case.
The lesion was in contact with the incudomalleolar joint.
Measurement 1: The distance by which the incudomalleolar
(IM) joint was anterior to the IAC.
In the normal anatomy, the incudomalleolar
joint is a saddle-shaped diarthrosis surrounded by an articular capsule.
1-3) Other types of injury include incudomalleolar
joint separation, dislocation of the incus, dislocation of the incudomalleolar
complex, and fracture of the stapes.
The malleus and incus were fused, but an incudomalleolar
joint was seen.
