Chronic maxillary sinusitis
Springer Online Journal Archives 1860-2000
Abstract Computed tomography (CT) is valuable in differentiating between maxillary sinus carcinoma and chronic maxillary sinusitis because destruction of the maxillary sinus bone wall is the most characteristic finding of maxillary sinus carcinoma. However, some reports have described the existence of chronic maxillary sinusitis with bone destruction of the maxillary sinus walls. Therefore, the CT finding of bone destruction is insufficient to differentiate between maxillary sinus carcinoma and chronic maxillary sinusitis. For this reason, we devised methods of combined diagnosis using CT and67Ga scintigraphy to increase the diagnostic accuracy when differentiating between the two conditions. Twenty-four patients with maxillary sinus carcinoma and 13 patients with chronic maxillary sinusitis underwent CT and67Ga scintigraphy. The sensitivity, specificity, and accuracy values obtained were 1.00, 0.85, and 0.95, respectively.
