Definition

The nasal septum is the wall that separates the left and right nostrils. A centered septum allows air to flow equally through each nostril. In a deviated nasal septum, the wall is not centered.

A deviated septum may cause no symptoms at all. In severe cases, airflow through one or both nostrils may be blocked. A blocked nostril may cause chronic stuffiness and a tendency to get sinus infections .

Causes

Causes include:

    
  • Present at birth—arose during fetal development (5% of cases)
  • Birth injury to the nose
  • A blow to the nose, often during an accident or while playing sports
  • Risk Factors

    Risk factors include:

        
  • Contact sports, especially karate or football without appropriate protective headgear
  • Trauma is the most common risk factor
  • Symptoms

    Symptoms include:

        
  • Stuffy nose (one or both sides)
  • Sinus infections
  • Nosebleeds
  • Breathing noisily during sleep
  • Facial pain or headache
  • Diagnosis

    The doctor will ask about your symptoms and medical history. A physical exam will be done. The doctor will examine the nasal passages. A nasal speculum will hold the nose open. A thin telescope is passed into the nose.

    Treatment

    Most people will not require treatment. In severe cases, surgery may be needed. Surgery on the septum alone is called septoplasty . It relieves nasal blockage by centering the septum between the two nostrils.

    Sometimes surgery to reshape the nose ( rhinoplasty ) is performed at the same time. The two procedures together are called septorhinoplasty. Children who need surgery usually wait until they have stopped growing, around age 16.

    Prevention

    To help prevent a deviated septum:

        
  • Wear seat belts in automobiles and airplanes
  • Wear appropriate protective headgear when playing sports
