Mucosal Cysts of the Maxillary Sinus: Report of 75 Cases

Abstract

Review of panoramic radiographs revealed 75 patients with mucosal cysts in the maxillary sinus. The medical histories of these patients, signs and symptoms of sinus disease, routine intraoral radiographic findings, and detailed analyses of dental pathosis in close proximity to the involved sinus were related to the occurrence of the condition. This study indicates an incidence of about 2% in a dental school clinic population. The incidence of related symptoms was higher than that reported in previous studies. The role of dental pathosis as a possible etiologic factor is discussed. Review of panoramic radiographs revealed 75 patients with mucosal cysts in the maxillary sinus.
