Sinusitis can be subdivided into acute, subacute, and chronic disease.Acute sinusitis is defined as disease lasting less than 1 month.indings of acute sinusitis include an air-fluid level, mucosal thickening, and complete opacification of the sinus. Blood in the sinus due to recent trauma may mimic an air-fluid level in the sinus, but it is easily distinguished by density measurements. In chronic sinusitis, the ethmoid sinus is commonly involved.
