What causes nasal septum deviation?
Septal deviation can be caused by an injury to the septum from a punch to the nose or during water polo. If the deviation is too severe, it can obstruct nasal drainage and mimic sinusitis, or it can predispose one to secondary sinusitis. Fortunately a deviated septum can be corrected with an operation called a septoplasty. However, if a surgery is done incorrectly, it may serve to exaggerate the deformity.
