【Abstract】 With the development of Stomatology，more and more branches of Stomatology need to consider the anatomical factors of maxillary sinus septa in clinical diagnosis and treatment. Its position，direction and height directly affect the scheme formulation and treatment effect. Cone beam CT can provide a large number of noninvasive and accurate data，which is conducive to the study of maxillary sinus septa. In this paper，we reviewed the application of cone beam CT in measuring the anatomical structure of maxillary sinus septa.
