Types of the ossicular injuries include incudostapedial joint separation; incudomalleolar joint separation; incus dislocation; malleoincudal complex dislocation; stapediovestibular dislocation; and fractures of malleus, incus, and stapes (1).
Most of these cartilage areas are located in the incus body near to the short crus and the articulation area of the incudomalleolar joint (Figures 3(b) and 3(d)).
Then the posterior ear canal wall was worn thin to gradually open the attic forward and to expose the incudomalleolar joint. Afterwards, tissues with pathological changes in the mastoid cavity and the attic were carefully removed.
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.
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.
We report a case of synovial chondromatosis of the middle ear (i.e., the incudomalleolar joint) in a 64-year-old woman, and we describe the clinical, radiologic, and intraoperative findings in this case.
This finding might be more attributable to the increased rigidity of the ossicular chain secondary to incudomalleolar joint dysfunction than to a mass effect.
In the normal anatomy, the incudomalleolar joint is a saddle-shaped diarthrosis surrounded by an articular capsule.
When the incudomalleolar joint is disrupted, the body of the incus is usually rotated and displaced superiorly, posteriorly, and laterally.
(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.
To allow a better ET exposure, the facial recess is first opened, the incudostapedial and incudomalleolar joints are disarticulated, and the incus is removed.
