Three-dimensional assessment of maxillary sinus volume in a Vietnamese population using CBCT

Background: The maxillary sinus is an important anatomical structure in many fields, particularly dentistry and maxillofacial areas, due to its proximity to the working region. Objective: To assess the correlation between maxillary sinus volume (MSV) and gender, age, and the condition of the maxillary molars. Materials and Methods: The study involved 130 patients from the Can Tho University of Medicine and Pharmacy Hospital. CBCT imaging was done with precise positioning and settings using a Sirona Orthophos SL 3D device. Radiographs were processed with Mimics Research software. Results: There was no statistically significant difference in MSV between sides. Volume peaked at 18–24 years and decreased with age, consistently being higher in males than in females. Individuals missing maxillary molars had smaller sinuses, but the difference was not significant. Regression analysis identified age and gender as key factors, with age being primary. These findings support understanding the effects of age and gender on sinus volume in anatomical and clinical research. Conclusion: The study demonstrates that MSV varies according to gender and age, underscoring the importance of understanding demographic characteristics and utilizing advanced imaging technologies in dental treatment planning. This provides an overview of the anatomical features of the maxillary sinus in the Vietnamese population, in particular, and the Asian population in general. These findings play a crucial role in clinical planning, especially in dental implant placement and sinus augmentation procedures that are closely and directly related to the maxillary sinus.
