Pneumatization of Mastoid Air Cells: Role of Acquired Factors Neumatización de las Células Mastoideas: Rol de Factores Adquiridos
نویسندگان
چکیده
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. Allam (1969) classified the pneumatized spaces of the temporal bone into five different regions: middle ear region, mastoid region, perilabrynthine region, petrous apex region and accessory region. This air cell system is lined by a flattened, non-ciliated squamous epithelium.

متن کاملComputed tomography of temporal bone pneumatization: 1. Normal pattern and morphology.
The pneumatization of 141 "normal" temporal bones on computed tomography (CT) was evaluated in 100 patients (age range, 6-85 years). Because of the controversy surrounding the sclerotic squamomastoid (mastoid), temporal bones with this finding were discarded. A CT index of pneumatization was based on the pneumatized area and the number of cells seen within a representative scanning section. Res...

متن کامل[Pneumatization of the petrous apex].
Pneumatization of the petrous apex was investigated in 226 subjects without middle ear disease by means of target imaging CT. The degree of pneumatization of all subjects was 32.7% (148/452 ears), but no difference in degree was revealed with distinction of bilateral ears or between sexes. In 148 ears with pneumatization of the petrous apex, a higher degree of pneumatization was found in larger...
