Objective: Due to region of maxillary sinus it is one of the region both department of ear, nose and throat and department of oral and maxillofacial surgery are frequently encountered relationship between odontogenic infections and maxillary sinusitis has been shown in literature. For correct design of the lateral window during sinus floor elevation operation, radiographic identification of septa is important. The aim of this study is to compare cone-beam computed tomography (CBCT) and panoramic radiography methods in determining the presence and location of maxillary sinus septa and pathologies. Material and Methods: This study was performed with CBCT and panoramic images of patients in department of oral and maxillofacial surgery between September 2010 and September 2021, retrospectively. Results: In CBCT images, 64 (30%) of 214 patients and 112 (27.3%) of 410 sinuses had maxillary sinus septa. In panoramic images, 44 (20.5%) of 214 patients and 89 (21.7%) of 410 sinuses had maxillary sinus septa. In CBCT images, 30 (7.3%) in the anterior region, 70 (17.1%) in the middle region, 6 (1.5%) in the posterior region and 6 (1.5%) septa located in any 2 of these 3 regions at the same time. In panoramic images 14 (3.4%), 61 (68.5%) in middle, 8 (9%) in posterior and 3 (3.3%) septa located in any 2 of these three regions at the same time. Conclusion: To avoid complications during sinus floor elevation surgery, examination by computed tomography is required as panoramic radiography has proven to have low sensitivity and specificity in identifying these structures.
