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 patients presenting with frontal sinusitis. Bone scans, classified according to 99Tcm-methylenediphosphonate (MDP) distribution patterns indicated both active and resolving sinusitis as well as surgically related bone trauma. Gallium scan uptake intensity correlated well, however, with final outcome and differentiated between active and resolving sinusitis, more specifically than corresponding bone scans. Thus combined studies appear to have a significant role in the diagnosis and management of patients suspected for frontal sinusitis.
