title: Bone scintigraphy in the diagnosis of fracture and infection of the temporal bone.
abstract: The sensitivity of 99mTc-MDP-bone-scintigraphy in the diagnosis of temporal bone fracture was found equal to that of conventional radiography if the patients were examined 10 days after the trauma. Temporal bone osteomyelitis with concomitant moderate osteosclerosis was demonstrated by bone scintigraphy in 5 cases of mastoiditis with atypical symptoms. A case of apicitis was for the first time demonstrated by scintigraphy. A low sensitivity of 67Ga-scintigraphy was demonstrated by positive 99mTc-bone-scintigraphy and negative 67Ga-scintigraphy in a patient with atypical mastoiditis. 99mTc-scintigraphy was negative in 5 cases of otitis media suppurativa and in 3 cases of otitis media chronica cum cholesteatoma, all with slight degree of osteosclerosis in the mastoid. The sensitivity of 99mTc-bone-scintigraphy in fracture and osteomyelitis of the temporal bone seems to be a function of the amount of reactive new bone formed.
