%X Comprehending the architecture of maxillary sinus and its septa is crucial for preventing complications during maxillofacial procedures, as it guides clinicians in selecting optimal surgical techniques. This study used cone-beam computed tomography (CBCT) to examine anatomical variations of maxillary sinus and its septa. CBCT scans of 500 dentate patients aged 25–65 years who underwent head and neck imaging at Department of Radiology, Saveetha Dental College and Hospitals, Chennai, India, between January and June 2024 were analyzed. Measurements included maxillary sinus dimensions, lateral wall thickness, septa prevalence and location, septa orientation, and perforation risk on both sides. Independent t-test was used to compare differences between the right and left sinuses. The mean maxillary sinus width was 23.20 ± 4.22 mm on the right and 23.73 ± 4.62 mm on the left (p=0.705); depth was 33.39 ± 3.53 mm on the right and 34.57 ± 3.27 mm on the left (p=0.280); and height was 34.44 ± 2.44 mm on the right and 35.16 ± 2.24 mm on the left (p=0.282), none showing significant differences. The lateral wall thickness at 3 mm measured 2.10 ± 1.20 mm on the left and 2.40 ± 1.31 mm on the right (p=0.457). Most septa were located in the middle region with mediolateral orientation, and moderate perforation risk predominated. The results demonstrated no significant bilateral variation in maxillary sinus dimensions, with average wall thickness ranging between 2–3 mm. Routine assessment of sinus anatomy and septa is essential to reduce surgical risks and enhance treatment outcomes.
