Computed tomographic measurement of maxillary sinus dimensions and its association with age and gender in Rajshahi City

Background: A racial variation of paranasal sinus growth is observed with age and sex. Methods: This cross-sectional type of descriptive study was carried out in the Department of Anatomy, Rajshahi Medical College, Rajshahi over a period of 1 year among the apparently healthy people within the age of 11- 60 years. CT scan machine and Computer were used to gather data from 100 respondents by convenient sampling technique. Results: The height of the maxillary sinuses (both right and left) was observed to be significantly heterogeneous with maximum height being attained at 3rd decade and minimum at 6th decade of life (p = 0.045 and p = 0.024, respectively). While width of the left maxillary sinus was significantly greatest at 3rd decade, it is shortest at 2nd decade of life (p = 0.037) and depth of the left maxillary sinus was significantly greatest at 5th decade, it is shortest at 2nd decade of life (p = 0.019). Except width of the left maxillary sinus, all the dimensions were significantly greater in male than female (p < 0.05) and right sided all dimensions in both sexes were found to bear linear relationship with those of their left side. Conclusion: This study might help us in creating a database of our country people which provide an important role during maxillary sinus surgery.
