What Is Meant By A Deviated Nasal Septum?

A deviated septum happens when the thin wall (nasal septum) between your nasal sections is dislodged aside. In numerous individuals, the nasal septum is askew — or deviated — making one nasal section more modest.

At the point when a deviated septum is severe, it can impede one side of your nose and decrease wind stream, causing trouble breathing. The extra openness of a deviated septum to the drying impact of wind current through the nose may once in a while add to crusting or seeping in specific individuals.

A nasal blockage can happen from a deviated nasal septum, from swelling of the tissues covering the nose or from both. Treatment of nasal obstruction may incorporate prescriptions to decrease the swelling or nasal dilators that help open the nasal sections. You also may require surgery to address a deviated septum.


Most septal distortions bring about no symptoms, and you may not realize you have a deviated septum. Some septal deformations, be that as it may, may cause the accompanying signs and symptoms:

  • Obstruction of one or the two nostrils

This blockage (obstruction) can make it hard to inhale through the nostril or nostrils. You may see this more when you have a cool (upper respiratory parcel contamination) or sensitivities that can make your nasal entries swell and thin.

Nosebleeds. The outside of your nasal septum may become dry, expanding your danger of nosebleeds.

  • Facial agony

 There is some discussion about the conceivable nasal reasons for facial agony. A potential reason for uneven facial torment could be a severe deviated septum where surfaces within the nose contact and cause pressure.

  • Boisterous breathing during rest

 A deviated septum or swelling of the intranasal tissues can be one of the numerous explanations behind loud breathing during rest.

  • Inclination for resting on a specific side

 A few people may like to rest on a specific side to streamline breathing through the nose around evening time on the off chance that one nasal entry is limited.

A deviated septum is a condition in which the nasal septum, the bone and cartilage that divide the nasal cavity of the nose in half, is significantly off center, or crooked, making breathing difficult. Most people have some sort of imbalance in the size of their breathing passages. In fact, estimates indicate that 80% of people, most unknowingly, have some sort of misalignment to their nasal septum. 


An injury to the nose can cause a deviated septum. Nasal injuries may occur due to:

  • Sports
  • Falls
  • Car accidents
  • Getting hit in the nose during an accident or fight

A deviated septum may also be congenital, or present at birth. The deviation may be from a difficult birth or connective tissue disease.

It may also be a result of normal development. As the nose grows, the septum also grows and can sometimes grow towards one side. This is typically the most common reason to have a deviated septum.


Most septal displacements result in no symptoms, and you may not even know you have a deviated septum. Some septal deformities, however, may cause the following signs and symptoms:

Obstruction of one or both nostrils: This blockage can make it difficult to breathe through the nostril or nostrils. You may notice this more when you have a cold or allergies that can cause your nasal passages to swell and narrow.

Nosebleeds: The surface of your nasal septum may become dry, increasing your risk of nosebleeds.

Facial pain: There is some debate about the possible nasal causes of facial pain. A possible cause of one-sided facial pain could be a severe deviated septum in which surfaces within the nose touch and cause pressure.

Noisy breathing during sleep: A deviated septum or swelling of the tissues in your nose can be one of the many reasons for noisy breathing during sleep.

Awareness of the nasal cycle: The nose alternates between being obstructed on one side and then changes to being obstructed on the other. This is called the nasal cycle. Being aware of the nasal cycle isn't typical and can indicate nasal obstruction.

Preference for sleeping on a particular side: Some people may prefer to sleep on a particular side to optimize breathing through the nose at night if one nasal passage is narrowed.


Your doctor will talk to you and examine you. The doctor may use a nasal endoscope, a long tube with a bright light at the tip, to see further back into your nose.

Conditions other than a deviated septum can cause nasal congestion. For example, you may have a different kind of structural problem inside your nose, chronic sinusitis or allergies. In rare cases, bleeding and blockage can be signs of a nasal tumor.
