The mastoid air cell system represents a more or less extensive system of interconnecting air filled cavities arising from the walls of the mastoid antrum and walls of the middle ear.
Opponents of mastoidectomy argue that the mastoid air cell system is thought to function, at least in part, as a buffer to the changes in pressure within the middle ear.

The areas of the mastoid air cells were measured on preoperative CT scans.
The pre-operative CT scans were reported to assess characteristic cholesteatoma findings, location and extension of soft tissues in middle ear, integrity of scutum, erosion of the ossicular chain, integrity of the thin bony septum of facial nerve canal, the semicircular canals and the tegmenextension of cholesteatoma outside the middle ear, integrity of mastoid air cells, trabeculae, as well as relationship and proximity of soft tissues with the tympanic membrane were assessed.
