Obesity and its effects on the upper airway tissues
Increased neck circumference
Nasal airway restriction:

  • septal deviation,
  • allergic rhinitis,
  • nasal polyps

Macroglossia/tongue ridging
Adeno-tonsillar hypertrophy (palatine/lingual tonsils)
Lateral peritonsillar narrowing
Enlargement/elongation of the soft palate
Recessed mandible (retrognathia)/maxilla
Narrowed hard palate – overbite/overjet
A combination of soft tissue and/or craniofacial risk factors is likely most important
