The nasal septum is made of bone and cartilage and it divides the right and left sides of the nasal cavity. Normally, the nasal septum lies in the center of the nose and rests on the maxillary crest (bony part of the floor of the nose).
When the nasal septum does not align with the middle of the nose it is called a Deviated Nasal Septum. This may have occurred from trauma, perhaps as a child, or you may have been born with a deviated septum. Almost everyone naturally has some curvature or crookedness to his or her septum. If the septum is too deviated it may block one side of the nose or obstruct the openings of the sinuses causing recurrent sinus problems requiring a Septoplasty.
