Abstract
Background: Maxillary sinus septum is an anatomical variation in the maxillary sinus. It is a crucial structure that needs to be evaluated during sinus elevation procedure. As the risk of membrane perforation increases when anatomical variation such as antral septa are present. The study was conducted with the objective to evaluate prevalence and location of maxillary sinus septum.Methods: The study is based on analysis of digital orthopantomogram images that are obtained from patients who visited Farooqia Dental College and Hospital, Mysuru. A retrospective analysis of 400 maxillary sinuses (200 pairs) is done. The orthopantomogram images which exhibited any sinus pathology/fracture are excluded from study. Orthopantomogram was analyzed by examiners to confirm the presence/absence of sinus septum. Patients not having maxillary sinus septum on both sides are considered absence of sinus septum.Results: Prevalence of maxillary sinus septum was found to be 21%. Maxillary sinus septum was found in 49 patients on left side and 35 patients on right side.Conclusion: Study infers significant prevalence of septum with maxillary sinus that would aid to prevent complications during sinus lifting procedure.DOI:10.21276/AOHDR.1912References
