A blocked nose is a common and frustrating condition. A chronically blocked nose may be caused by structural and/or inflammatory conditions of the nose.

Common structural problems include:

  • Deviated septum
  • Enlarged turbinates
  • Concha bullosa
  • Nasal valve problems

Common inflammatory conditions include:

  • Acute or Chronic sinusitis
  • nasal polyps
  • nasal allergy / hayfever / "allergic rhinitis"
  • nasal tumours

The diagnosis is made by a detailed history and examination including nasendoscopy (camera inspection inside the nose). Occasionally, scans are ordered. We will also consider allergy testing, smell testing and nasal airflow studies (rhinomanometry) where necessary. 

A blocked nose is important to treat in both adults and children. In children, it may affect sleep, exercise tolerance, and impact growth of the teeth, palate and facial bones. In adults, poor sleep, headaches, reduced concentration and even sleep apnea may be potential consequences.
