title: Odontogenic keratocysts of the midline maxillary region.
abstract: OBJECTIVE
  This article compares the demographic features of the anterior midline maxillary odontogenic keratocyst with those in other regions.
  
  
  METHODS
  The data on 18 cases of anterior midline maxillary odontogenic keratocyst were reviewed.
  
  
  RESULTS
  Thirteen of the cases were in men (72.2%), and 16 of the patients (88.9%) were past the age of 60 years. The mean age of the patients was 69.9 years, which is much higher than for odontogenic keratocysts in other locations. The most common clinical diagnoses were periapical cyst and nasopalatine duct cyst.
  
  
  CONCLUSIONS
  It is important to include odontogenic keratocyst in the differential diagnosis of anterior midline maxillary radiolucencies, especially when they occur in older individuals.
