rhinosinusitis resolves in
acute
rhinosinusitis resolves 30-90d
subacute
rhinosinusitits w 3 episodes

rhinosinusitis >90d w persistent symp
chronic sinusitis
path of viral rhinosinusitis
- direct inoculation via direct contact
- virus spreads paranasal sinuses by blowing nose and inc intranasal pressure that can impair nasal cilia
pt presents w mucosal edema, copious thickened secretions, and ciliary dyskinesia
