Radiographic maxillary sinus findings in the elderly.
The prevalence of radiographic maxillary sinus findings in 293 elderly subjects (76, 81, and 86 years old) were investigated with the use of panoramic radiography: 124 subjects were edentulous in both jaws, 167 had an edentulous maxilla, and 169 had at least one natural tooth left. Mucous cysts or diffuse mucosal thickenings were found in 12% of the subjects. Of the mucosal thickenings, 70% were found in subjects with a dentate upper jaw (p < 0.05), suggesting an odontogenic origin for that proportion (40%) exceeding the prevalence in subjects edentulous in the maxilla. That the prevalence of mucous cysts was 5% both in subjects with a dentate upper jaw and in those with a edentulous upper jaw suggests nonodontogenic causes.
