Definition of rhinosinusitis by the American Academy of Otolaryngology Head and Neck Surgery [18]

Major factors
Facial pain/pressure
Nasal obstruction/blockage
Nasal discharge/purulence/discolored postnasal drainage
Hyposmia/anosmia
Purulence in nasal cavity on examination
Fever (acute rhinosinusitis)
Minor factors
Headache
Fever (all nonacute)
Halitosis
Fatigue
Dental pain
Cough
Ear pain/pressure/fullness

Two major factors or one major and two minor factors are required for the diagnosis. Of note, facial pain requires another major factor associated with it for diagnosis, as facial pain plus two minor factors is not deemed sufficient for diagnoses of rhinosinusitis
