Abstract:
Objective To explore the volume size of mastoid pneumatization in normal adults and the relation‐ship with a history of recurrent otitis media in childhood .Methods A total of in 40 adults (80 ears) ,based on with or without otitis media in childhood ,were divided into the study group (n= 20) and the control group (n=20) . The volume sizes of mastoid pneumatization were measured by temporal bone CT scanning of three-dimensional re‐construction ,and the relationship with the history of childhood ear infections was studied .Results The average vol‐ume of pneumatization in all 80 temporal bones was 10 .4 ± 1 .8 ml .The average volume of pneumatization in sub‐jects without otitis media history (48 ears) and subjects with a history of otitis media (32 ears) were 9 .7 ± 2 .2 ml and 6 .3 ± 1 .7 ml ,respectively .The difference was statistically significant (P<0 .05) .For the subjects with single ear disease in the study group ,the average volume of pneumatization in subjects without otitis media history(8 ears) and subjects with a history of otitis media(8 ears) were 9 .2 ± 1 .3 ml and 5 .8 ± 3 .6 ml ,respectively ,and there were statistically significant differences(P<0 .05) .The average volume of pneumatization in the control group (40 ears) was 10 .1 ± 4 .4 ml .Comparing with the subjects with out otitis media history(8 ears) in the study group ,there was no statistically significant difference (P>0 .05) .Conclusion The volumes of mastoid pneumatization in normal ears have a wide range .The subjects with a history of recurrent otitis media in childhood may be the cause of the volume decrease of mastoid pneumatization in adulthood .
