THE COMBINED USE OF CLASSIFIED BONE AND GALLIUM SCANS IN THE MANAGEMENT OF FRONTAL SINUSITIS

Bone and gallium scans of the sinus regions were performed in 32 patie nts presenting with frontal sinusitis. Bone scans, classified accordin g to Tc-99m-methylenediphosphonate (MDP) distribution patterns indicat ed both active and resolving sinusitis as well as surgically related b one trauma. Gallium scan uptake intensity correlated well, however, wi th final outcome and differentiated between active and resolving sinus itis, more specifically than corresponding bone scans. Thus combined s tudies appear to have a significant role in the diagnosis and manageme nt of patients suspected for frontal sinusitis.
