Tomographic features of the maxillary sinus septa in patients of the dental clinic of the Universidad Peruana Cayetano Heredia. Rev. Estomatol. Herediana [online]. 2019, vol.29, n.2, pp.128-136.

The septa of the maxillary sinus are anatomical variants that are formed as a result of the residues of hypoplasia in different areas of the alveolar process, being of variable shape, size and number.Your finding can be made using routine panoramic radiographs. The importance of a septum in the maxillary sinus is that it can generate modifications for maxillary sinus surgeries, and it may be necessary to open two or more surgical windows for its removal. Objective: The purpose of this study was to analyze the tomographic features of the maxillary sinus septa in patients who attended the teaching dental clinic of the Universidad Peruana Cayetano Heredia between 2014- 2016. Materials and methods: This research was cross-sectional and descriptive, for which 813 cone beam CT scans were examined. Chi square test and descriptive statistics were used for the analysis, with a 95% confidence interval, with a value p < 0.05. Results: 298 patients presented septa, with a higher percentage of congenital septa (69.2%) and were more common in female patients with 36%. Conclusions: the congenital type septa prevailed, which indicates that they were formed from root development.
