Abstract: | To assess the usefulness of CT images for the diagnosis of suspected odontogenic maxillary sinusitis, 52 patients with maxillary
sinusitis who had received CT examination were retrospectively analyzed. maxillary sinus ostium was established on coronal
CT image in 20 out of 55 lesions in those 52 patients. However, a considerable number of patients who had inflammatory disease
not only in the maxillary sinus but also in other paranasal sinuses (38/55) or in the nasal meatus (34/55) were included in
those 52 patients. Concerning the opening of the ostium, the clinical diagnosis is frequently different from the diagnosis
made using CT. The CT findings of the maxillary sinus ostium, nasal meatus and other paranasal sinuses were thus important
in planning the treatment for patients with maxillary sinusitis in dentistry, as in otorhinolaryngology. |
