The temporal bone is a complicate structure which located on the lateral skull. The objective of the present
study was to determine the temporal bone air spaces’ morphometry, morphology, and pneumatization in Turkish healthy adult people.
This retrospective observational study was carried out from 82 subjects (47 males, 35 females) aged 18-69 years. The external auditory
canal and related structures’ diameters and the volume of these areas were evaluated. The means and standard deviations of the Meatus
acusticus externus length (MAEL), meatus acusticus externus pars cartilaginea length (MAEcL), meatus acusticus externus pars ossea
length (MAEoL), meatus acusticus externus pars cartilaginea surface (MAEcS), meatus acusticus externus pars ossea surface (MAEoS),
meatus acusticus externus volume (MAEV), meatus acusticus externus pars cartilaginea volume (MAEcV), meatus acusticus externus
pars ossea volume (MAEoV), processus mastoideus air cells volume (PMACV), cavum tympani volume (CTV), and temporale
pneumatic spaces volume (OTPSV) were found as 23.21±3.70 mm, 12.69±3.72 mm, 7.80±3.70 mm, 669.89±107.7 mm2

, 7813.34±717.49 mm3
have found in 82 subjects, respectively. In this paper, the morphometric and volume properties of the temporal bone cavities measurements
were significantly higher in males than females. These results may both provide reference values of Turkish healthy population, and
lead to decrease potential surgical complications about temporal and mastoid regions.
