Rhinosinusitis is the inflammation of the nasal mucosa and paranasal sinuses. The terms<unk>  and rhinosinusitis are used interchangeably, although rhinosinusitis is preferred because inflammation of the paranasal sinuses rarely ever occurs without concurrent inflammation of the nasal mucosa.  The cause of rhinosinusitis is mostly infectious, although it can be associated with other medical conditions such as allergies. The diagnosis is primarily clinical and imaging and other diagnostic studies are not necessary for diagnosis.
