The favorable prognostic factors affecting outcomes in ossicular chain reconstruction are a low level of otorrhea [6, 16], the presence of malleus handle [6, 8, 12, 13, 15-17], the presence of stapes superstructure [7, 9, 12, 14, 17], normal stapes mobility [12], the presence of chorda tympani nerve [10], normal middle ear mucosal status [12-14, 16], intact canal wall tympanomastoidectomy (CWU) [5, 10, 11, 16], primary surgery [9-11, 16, 17], and local anesthesia [12].
Traumatic ossicular injuries are usually associated with longitudinal temporal bone fractures (1, 3).
The study also revealed that of the HIV positive group a larger proportion of cases had documented ossicular disease, or erosion, when compared to the rest (50% compared to 22.5%), with only 10% of patients falling within the criteria for BROT preoperatively compared to 28.8% in the rest.

Our study showed that hearing improvement was possible following surgery with CWU tym-panoplasty and ossicular chain reconstruction.
The generated model consists of the outer shape of the ossicles with its ligaments, muscles, the articular capsules of the ossicular joints, and the articulation cartilage on the joint surface.
There are many ways to reconstruct the ossicular chain, but the results are not always satisfactory because it is being done usually by columella (bird) effect, which sometimes is unsatisfactory for hearing impairment.
Radiological signs indicating cholesteatoma in the attic included erosion or destruction of scutum or spur (the lateral wall of the attic), widening of the aditus ad antrum (loss of figure of "8" appearance) , antral wall erosions and widening , ossicular erosions and destruction , medial attic wall erosion which may lead to facial nerve canal involvement, which may cause paresis or paralysis , erosion of the lateral semicircular canal which may result into fistula formation (Figure 1), dehiscence of tegmen tympani , dehiscence of sigmoid sinus plate, erosion of the external auditory canal (EAC), and automastoidectomy.

Pars flaccida cholesteatomas are the most common and begin along the pars flaccida, grow into the epitympanum in Prussak's space (attic cholesteatomas), lateral to the ossicular chain.
