Abstract:

Objective To observe the anatomic morphology of the normal maxillary sinus using cone-beam computed tomography(CBCT)and evaluate its variation to age and gender, helping clinicians to understand the anatomy of the normal maxillary sinus and to anticipate the selection of treatment plans. Methods CBCT data of 480 patients were selected and divided into 4 groups according to age:18-24 years old group, 25-39 years old group, 40-54 years old group and ≥55 years old group. The CBCT data were imported into Mimics software to measure maxillary sinus volume(MSV), surface area, and the morphology of the maxillary sinus floor(MSF) bilaterally. The correlation with age and gender was analyzed using SPSS software. Results There was no significant difference in MSV and surface area between the left and right sides(P>0.05), and the MSV and surface area of males were higher than those of females(P<0.05). MSV was greater in the 18-24 and 25-39 age groups than in the other two groups, and the measurement of surface area was the greatest in the 18-24 age group(P<0.05). There was no significant correlation between gender and MSF morphology(P>0.05), but there was a significant correlation between age and MSF morphology(P<0.05). Conclusion The volume and surface area of the normal maxillary sinus are affected by age and gender and decrease with age, but the maxillary sinus morphology is symmetrical on the left and right side.

Key words: cone beam computed tomography, maxillary sinus volume, maxillary sinus surface area, maxillary sinus floor
