Surgical exploration identified a large tumor that involved the mastoid air cells
from the mastoid antrum all the way up to the stylomastoid foramen.
The main goals of this technique are to completely eradicate the disease, create a large enough meatus for examination and mastoid air cells
, and provide a self-cleaning epithelized dry cavity, and achieve maximum hearing.
Aeration of the temporal bone was also evaluated by preoperative CT scan and divided into the following four categories: the mastoid air cells
, the epitympanum, the mesotympanum, and non-aerated.
A unilocular ZACD appears as radiolucency with well defined borders, while the multilocular type demonstrates numerous small cavities within, which resemble mastoid air cells
5] In majority of the adult cholesteatoma patients mastoid air cells
are very few in number and sclerotic [1, 5, 7, 8] Also at the same time trabeculations are lost in these patients.

Computed tomography scan of the temporal bones showed significant diffuse soft tissue swelling along the right aspect of the face and temporal bone with opacification of the middle ear and mastoid air cells
on the right.
CSF leaks results from a communication way that takes place between the subarachnoid space, the mastoid air cells
, the middle ear, the petrous apex air cells, and finally either the Eustachian tube (ET), the surgical incision, or a tear in the tympanic membrane [7-10, 12-17].

This can be accompanied by a concomitant shading of the mastoid air cells
, which could manifest as a reduced opacity on computed tomography (CT) in the absence of a history of chronic mastoiditis or acute inflammatory signs.
