Measurements Of Maxillary Sinus In Correlation To Age And Gender By Computed Tomography

ABSTRACT

Introduction: The sinonasal region is often imaged because of infectious and allergic diseases of the nasal cavityand paranasal sinuses. Improved knowledge of normal pneumatization and development of paranasal sinusesis important to allow sinus diseases to be evaluated and an adequate treatment to be proposed.Materials and methods: 100 patients (72 males and 28 females) undergoing coronal and axial sections of computedtomography scan of maxillary sinus of head and neck aged between 1year to 90 years at the Radiology Department,Vydehi Institute of Medical Science & Research Centre Bangalore for reasons other than due to craniofacialabnormalities or sinus problem were taken for the study. Volume and dimensions of the maxillary sinuses withits anatomical variations were obtained. Mean, SD, significant difference between age & gender was calculated.Results: Maxillary sinuses in Males on both sides have higher values in mean height, depth and volume thanfemales except right side width which was lesser in value than females. All the mean parameters were more onleft sinus both in male and females, except mean height of right sinus in males, on side comparison all the meanparameters were more on right side in females. There is a significant difference in mean height of right and leftmaxillary sinus in between male and female. There is a significant difference on right and left side widthbetween male and female in the age group 51-60 yrs and 61-70 yrs. The maximum age growth in males was during11-20 yrs and 41-50 yrs in height, width and volume, in 21-30 yrs and 31-40 yrs in depth, later dimensions weredecreasing in growth by 61-70 yrs in height and 81-90 yrs both in depth, width and volume. In females maximumgrowth was in 21-30 yrs and 51-70 yrs for height, depth, volume, 11-20 yrs and 51-60 yrs for width dimensions, laterdecreases by 61-70 yrs onwards in height, width and 11-20 yrs in depth and volume.Conclusion: These results will be helpful in understanding normal and pathological conditions of the maxillarysinuses and useful in clinical planning of medical or surgical interventions of the maxillary sinuses
