Abstract
Odontogenic sinusitis is caused by dental infection. The source of the infection is usually teeth after poor root canal therapy. Although the number of cases of untreated dental caries is decreasing, we treated 14 cases by dental and rhinologic treatment and the symptoms improved. The Lund-Mackay staging system1) was used for assessing disease extent and clinical management. The average score of preoperative CT scans was 5.9 points, and that of postoperative CT scans at 6 months after the operation was 0.5 points, showing a remarkable improvement. Therefore, in this disease, it is important to perform both dental-oral and otorhinolaryngology treatment, through close coordination and a deeper understanding of this disease. This report describes dental and rhinologic treatments that produced good results. It is suggested that more minimally invasive treatment may result in healing.
