Cross-sectional study estimating prevalence of maxillary sinus septum in South Indian population

Abstract

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
