Abstract
To study the Computerized Tomography (CT) Paranasal Sinus findings in patients with acute bacterial sinusitis and the clinical symptom associated with it. 120 patients were examined over 2 years with coronal CT images of paranasal sinus with clinical symptoms of acute sinusitis of 2 weeks duration from the onset. Patients with symptoms of more than 2 weeks and patients with chronic sinusitis, immunocompromised status were excluded. Air mixed with fluid is seen like a Fizz of cola drink within the maxillary, frontal or sphenoid sinus, mucosal thickening of more than 5 mm, fluid level and presence of opacifications were used as evidence of acute sinusitis. 28 patients (23.3%) had Fizz sign (Air mixed with fluid seen as bubbles) coronal CT images of the paranasal sinus. The study demonstrated great variation in the CT paranasal findings amongst patients with suspected acute sinusitis. More than one sinus subsite was affected amongst pat ients in whom acute sinusitis was confirmed by CT Paranasal sinus imaging. We hereby highlight a new sign of air mixed with fluid which the senior author had named as Fizz Sign because of its resemblance to the fizz of dark cola drink.
