Evaluation of maxillary sinus pneumatization amongst different age groups and genders: A CBCT based study

Excessive pneumatization can reduce the available alveolar bone height, increase the risk of surgical complications and limit prosthetic options. Therefore, it is of interest to evaluate maxillary sinus pneumatization in 200 adults across three age groups by measuring the distance between the maxillary sinus floor and nasal cavity floor at posterior tooth sites. Men showed significantly greater MSP than women in Groups I and II (p=0.004 and 0.001), while Type I pneumatization predominated across all groups, decreasing from Group I to III. Excessive MSP reduces alveolar bone height, raising surgical risks and limiting prosthetics, with variations by age, gender, and dental status aiding treatment planning.
