Deviated Nasal Septum

The nasal septum divides one side of the nose from the other. In some patients the septum is perfectly straight, however, in many patients it is bent to one side. Significant septal deviations can be associated with nasal congestion, sinusitis, headaches, or snoring. A septal deviation can be present from birth or it can be acquired from nasal trauma. There is no medical therapy that can straighten a deviated septum, but an operation called septoplasty is effective.
