YR 2009 UL http://smj.org.sa/content/30/7/937.abstract AB OBJECTIVE: To retrospectively analyze the extraordinary pathologic entities inside the concha bullosa (CB).METHODS: Surgical interventions were performed on 136 patients (234 CB) at the Department of Ear, Nose, and Throat, and Head and Neck Surgery, Izmir Tepecik Training and Research Hospital, Izmir, Turkey between January 2002 and December 2007. Radiological and histopathological findings of these cases were reviewed retrospectively.RESULTS: In 203 (86.8%) of the 234 cases, only a pneumatized cavity was observed. The cavity was filled with purulent secretion in 13 (5.6%) cases. A bony septum, pyocele, polyp, ossifying fibroma, fungus ball, and cholesteatoma were the other extraordinary pathologies associated with CB.CONCLUSION: Although most of the CB cases have pneumatized cavity, it should be kept in mind that some extraordinary pathologies can be associated with CB.
