An in-depth knowledge of the physiology of the upper respiratory tract, as well as the developmental, clinical, and imaging anatomy of the maxillary sinus-in particular its relationship to the dentition, nose, and ethmoid and frontal sinuses-is necessary for appreciating the maxillary sinus's part in both health and disease. To this end, this study sought to validate MDCT as a volumetric tool for assessing maxillary sinus size.
Material and methods: The volume of the maxillary sinuses was evaluated by using MDCT in 140 patients. CT head pictures were viewed via DICOM viewing software, and an internal electronic calliper was used to measure the sinuses. The data was analysed using a t-test for independent samples and a discriminant function analysis.
Results: Over the course of this study, 140 adults took part. Right maxillary sinus mean estimated volumes ranged from 13.89 cm3 in patients aged 18-30 years, 15.87 cm3 in patients aged 31-40 years, 16.56 cm3 in patients aged 41-50 years, 15.88 cm3 in Patients aged 51-60 years, and 16.45 cm3 in patients aged 60 and over. The mean value of estimated volumes of the right maxillary sinus was greatest in the age group 41–50, and lowest in the age group 18–30. Patients between the ages of 18 and 30 had left maxillary sinus volumes of 13.70 cm3, those between 31 and 40 had 15.82 cm3, those between 41 and 50 had 16.50 cm3, those between 51 and 60 had 15.52 cm3, and those above 60 had 15.90 cm3. There was a significant difference between the estimated right maxillary sinus volumes for those aged 18-30 and those aged 41-50.
Conclusion: The present study concluded that MDCT volumetric analysis of maxillary sinus may be useful for identification of the paranasal sinuses and adjacent structures.
