The usual sequel of inflammation is necrosis, especially at the incudostapedial joint, on the lenticular process and the distal part of the long process of the incus, but destruction of the stapes superstructure or, rarely, of the malleus handle can also occur.
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).
After cutting stapedial tendon, incudostapedial joint is dislocated with right angle prick.
From the posterior tympanic artery, a branch with large diameter leaves the blood vessel near the incudostapedial joint (Figure 2(a)) and runs on the medial side of the incus' mucosa to the base of the long crus where it enters the bone through a nutrition foramen (Figure 2(c)).
In the meantime, the posterior external ear canal wall was worn thin downward to expose the incudostapedial joint and stapes, and to eliminate the infectious foci in the posterior tympanum.
Incudostapedial joint separation is the most common ossicular injury and is seen as widening of the joint on CT.
Furthermore, the incudostapedial joint in the tumor was separated, and the incus was removed subsequently.
Occasionally, adhesions to the incudostapedial joint will not lift with the nitrous oxide, so they are addressed through a small tympanomeatal flap that is lifted with a Rosen pick.
After exposure of the mastoid cortex and temporal bone, cortical mastoidectomy performed, short process of incus identified; then the posterior tympanotomy done in the triangle between facial nerve, chorda tympani nerve and small piece of bone left near the tip of the short process of incus, the incudostapedial joint identified just below and behind the oval window the round window niche is identified.
All residents totally recognized the stapes, long process of the incus, and incudostapedial joint through the endoscopic approach, while 80.9% reported a "total" identification of these middle ear structures during the microscopic approach.
Out of 6 patients with tympanosclerosis, malleo-incudal joint was involved in 4 cases (66.66%) and incudostapedial joint was involved in 2 cases (33.33%) (Table II).
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.
