torresi lack the suspensory process of the squamosal that in most sigmodontines contacts the tegmen tympani; in addition, the latter structure displays a variable development (Fig.
In our study, we got sensitivity and specificity for tegmen plates erosion were 83% and 84% and sinus plate was 100% and 97% respectively.
Involvement of the facial nerve, labyrinth, sigmoid sinus, and dura of the tegmen may also be seen.
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.
12] Other areas of erosion include the tegmen tympani, the bony plate covering the sigmoid sinus, the squama of the temporal bone and rarely the vestibular labyrinth.
In addition, the labyrinth was outlined to locate the SSC and to identify the space between the tegmen and dura.
