Maxillary sinus septum is an anatomical variation in the maxillary sinus. Sinus septum is also an important anatomical structure that complicates sinus lift procedure. Aim of the Study : This study evaluated the prevalence of maxillary sinus septa in the edentulous and dentate maxilla using digital orthopantomogram. Materials and Method: This study was based on the analysis of digital orthopantomogram images for posterior maxilla that were obtained from patients who visited a Private Hospital. A retrospective analysis of 921 pairs of nonpathological maxillary sinuses was done. Patients who had pathological findings were excluded from the study. Results: Sinus septum was present in 217 (23.6%) of the 921 pair of maxillary sinuses. Totally, 704 (76.4%) patients did not have maxillary sinus septum. Also, out of 527 male patients, 125 patients had the septum and out of 394 female patients, 92 patients had sinus septum. Conclusion: This study gives an idea about the prevalence of sinus septum that would help a surgeon prevent a few possible complications during sinus lifting
