A deviated nasal septum is one of the most common causes of difficulty in nasal breathing. The condition can lead to chronic nasal obstruction, sleep disturbances, and frequent upper respiratory tract infections.

Symptoms

  • stuffy nose
  • snoring
  • difficulty breathing
  • sleep problems
  • frequent infections
WHAT IS IT

The nasal septum divides the nasal cavity into two halves. Its deviation disrupts the normal airflow through the nose, leading to difficulty breathing and chronic discomfort. The condition can be congenital or occur after trauma.

TYPES
  • Congenital deviation of the nasal septum
  • Post-traumatic deviation
  • Mild deviation
  • Severe deviation
CAUSES
  • Nasal trauma
  • Congenital anatomical features
  • Uneven growth of nasal cartilage
  • Previous childhood injuries
SYMPTOMS
  • Difficulty in nasal breathing
  • Snoring
  • Sleep disturbances

  • Nasal discharge
TREATMENT

The main treatment is surgical and is performed through septoplasty – a surgical procedure to correct the position of the nasal septum and improve nasal breathing.

 SYNONYMS: Nasal septum deviation, crooked nasal septum, septal deviation, deviated septum, nasal deviation
