摘要：introduction: A deviated nasal septum can produce nasal obstruction and may block the sinus drainage “ door-ways”, triggering recurrent or chronic infection. The present study is based upon to find the relation of nasal septal deviation with chronic maxillary sinusitis. Materials and Methods: Two groups were made, one control group with midline nasal septum and other group with septal deviation to either right or left side and maxillary sinusitis were studied. Signs of chronic maxillary sinusitis such as mucosal thickening and air fluid level, were read using plane x-ray . Results: Findings suggested that there is a co-relation between the deviated nasal septum with chronic inflammation of maxillary sinus. Conclusion: Of all paranasal sinuses, Maxillary sinuses are most constant in shape and size, and also most commonly involved in chronic sinusitis. Deviated nasal septum was found to be the primary cause of chronic sinus disease in our study. Therefore, to treat sinusitis, septal deviation should be corrected.
