Extensive maxillary odontogenic keratocyst: review of the literature and report of a case.

Abstract

Odontogenic keratocysts arising in the maxilla are relatively uncommon, small unilocular lesions that rarely involve the maxillary sinus. This paper reviews the clinical, radiologic and histologic features of an extensive maxillary odontogenic keratocyst involving the maxillary sinus, and the complications associated with its management. The authors emphasize the importance of regular patient follow-up examinations and imaging studies in order to detect and treat recurrent lesions when they are small and well-localized.
