Enlarged turbinates are not sinusitis, but sinusitis can cause enlarged turbinates, which can also lead to sinusitis or prolonged sinus inflammation by blocking sinus drainage channels. Acute sinusitis is characterised by systemic symptoms such as chills, fever, loss of appetite and constipation, and local symptoms such as nasal congestion and headache. The clinical manifestations of chronic sinusitis are mainly runny nose, nasal chill, decreased sense of smell, etc., which may be accompanied by general symptoms such as mental discomfort, headache and dizziness.
