Causes of blocked nose

The major causes of blocked nose (also known as nasal obstruction or stuffy nose or nasal congestion) in children are:

  1. Allergic rhinitis;
  2. Adenoid hypertrophy;
  3. Nasal septal deviation;
  4. Narrow highly arched palate.

Blocked Nose in Children

The treatment of the common causes of blocked nose

  1. Allergic rhinitis; optimal medical management involves topical treatment with low dose water based surface acting non absorbed steroid spray occasionally supplemented by oral medications such as low dose Singulair. A predictive index for the ethicacy of medical management can be obtained by putting a topical sympathomimetic amine into the nose, waiting 5 minutes for the lining to constrict. This is the amount of nasal decongestion that optimal medical management can achieve. Where the lining of the nose has lost it’s elasticity or reversibility or when compliance with medication is poor the newer surgical treatments, particularly ENDOSCOPIC POWERED INFERIOR TURBINOPLASTY are very effective at permanently treating nasal obstruction due to allergic rhinitis.

  3. Adenoid hypertrophy: Adenoidectomy bearing in mind that up to one third of children have intranasal extension of adenoid tissue which is appropriately treated not only by curettage but also by transnasal powered resection.
  4. Nasal septal deformity: Indiscriminate surgery of the nasal septum can interfere with mid facial growth and development. Judicious septoplasty in children is can be safely performed but if you suspect that the main cause of nasal obstruction is nasal septal deformity, children should be referred to experienced paediatric rhinologists.
  5. Narrow highly arched palate; palate expansion by early orthodontic intervention. Common orthodontic abnormalities associated with chronic nasal obstruction and mouth open posture:
    • Openbite
    • Crossbite
    • Retrognathia
    • Overbite
    • Marginal Gingivitis

Sequence of events in altered facial growth and morphology associated with nasal obstruction

Long standing nasal obstruction of any cause leads to altered craniofacial growth which is more marked in children who are genetically susceptible to narrow highly arched palate. If the nasal resistance is increased two or three fold children adopt a chronic mouth open posture at rest. The altered position of the tongue and the lips causes the mandible to rotate downwards. This causes over eruption of the molars and a retro gnathic open bite. A lower tongue also leads to altered tone in the buccinator muscle which leads to a constricted maxilla, a narrow palate, crossbite and the associated altered muscle pressure leads to retroclined teeth.


Evidence strongly suggests that nasal obstruction => a mouth open posture => altered facial growth and morphology
