Deviated Septum

What is a deviated septum?

A wall of cartilage divides the nose into 2 separate chambers. It’s called the nasal septum. A deviated septum is when this wall is shifted away from the midline. This may cause congestion, problems with breathing, or nasal discharge.

The most common symptom from a deviated septum is trouble breathing through the nose. The symptoms are often worse on one side. In some cases, normal sinus drainage is affected. This can result in repeated sinus infections.

What causes a deviated septum?

You may be born with a deviated septum. Or it can result from injury, or damage from past treatments.

What are the symptoms of a deviated septum?

Other people normally can’t tell you have a deviated septum. Trouble breathing through the nose, or one side of the nose, is the most common symptom. You may also have stuffiness, congestion, or a feeling of fullness. A deviated septum can also impair normal drainage from the sinuses. This can lead to sinus infections that keep coming back (recurrent).

How is a deviated septum diagnosed?

Your healthcare provider will take a health history and do a physical exam. They will ask questions about any previous injury, and symptoms. The physical exam may be done with a handheld tool (nasal speculum) that lets your provider gently open the nostril a little. Or your provider may use a small lighted scope (otoscope) to look into an ear or a nostril. Your provider may also use look at your nasal or sinus passages (nasal endoscopy). This is done using a skinny, flexible lighted tube with a camera in it. If needed, a CT scan of the nose may be done.

How is a deviated septum treated?

Depending on the severity of your symptoms, surgery may be advised. Septoplasty is a reconstructive surgery done to correct a deviated nasal septum. The procedure is done through the nostrils. During the procedure, parts of the septum may be removed. Or they may be readjusted and reinserted into the nose.

Septoplasty may be done with traditional open surgery from inside the nose. When open surgery is done, small scars are made on the base of the nose. They are often not noticeable. Scarring is not visible when internal surgery is done. Depending on the severity of the deviation, septoplasty may be done in:

  • A surgeon's office
  • An outpatient surgery center
  • A hospital as an outpatient
  • A hospital as an inpatient

The surgeon will let you know when you can get back to normal activities. Many people recover in a few days. They can go back to school or to nonactive work in a week or so.

After surgery, you may have a splint on your nose to help hold its new shape. You may also have nasal packs or soft splints in your nostrils to stabilize the septum.

Short-term side effects of surgery may include:

  • Face will feel puffy
  • Nose may ache
  • Dull headache
  • Swelling around the eyes
  • Bruising around the eyes
  • Small amount of bleeding in first few days
  • Small burst (ruptured) blood vessels may look like tiny red spots on the skin

Healing is a slow process. You may have some swelling for months, especially in the tip of the nose. Final results of nasal surgery may not be clear for a year or more.

As with any surgery, there can be complications. People vary greatly in their anatomy and the ability to heal. The outcome is never fully predictable. Complications include:

  • Infection
  • Nosebleed or blood clot
  • Hole (perforation) in the septum
  • Reaction to the anesthesia
