The nasal septum
is the bone and cartilage in the nose that separates the nasal cavity
into the two nostrils. A deviated septum is an abnormal condition in which the top of the cartilaginous ridge leans to the left or the right, causing obstruction of the affected nasal passage. The condition can result in poor drainage of the sinuses. Patients can also complain of difficulty breathing
, headaches, bloody noses, or of sleeping disorders such as snoring or sleep apnea.
It is common for nasal septa to depart from the exact centerline; the septum is only considered deviated if the shift is substantial or is adversely affecting the patient Many people with a deviation are unaware they have it until some pain is produced. By itself, a deviated septum can go undetected for years and thus be without any need for correction.
