Marsupialization and peripheral ostectomy for the management of large odontogenic keratocyst: a case report

Odontogenic keratocyst has been of particular interest due to its distinctive behavior and its tendency to frequently recurrence and the diversity of treatment methods. Researchers have differed over the past decades about the nature of this lesion, sometimes it was classified as a cyst and sometimes it was classified as a tumor because of its specific histopathologic features, high recurrence rate and aggressive behavior. We discuss a case of a large odontogenic keratocyst (OKC) that was treated by marsupialization followed by peripheral ostectomy. Based on our findings, we conclude that the marsupialization followed by peripheral ostectomy was a conservative and effective option for the management of large OKC.
