Calculation of the mastoid cell volume of infants from computed tomography imaging.
OBJECTIVE
The objective of this study was to calculate the mastoid cell volume of infants using computed tomography imaging.


METHODS
We calculated the mastoid cell volumes of 87 infants younger than 1 year classified into 4 age groups.


RESULTS
There were significant (P = 0.0001) differences in the ear mastoid cell volumes (cm(3)) among the 0- to 3-, 4- to 6-, 7- to 9-, and 10- to 12-month age groups. Generally, the mastoid cell volume increased with age.


CONCLUSIONS
Mastoid cell volume correlates with the age of infants up to 1 year. We plan to expand this study and determine cutoff values for the mastoid cell volumes of infants.
