Abstract

|
The odontogenic keratocyst is well known for its tendency to recur, its specific histopathologic feature and potential aggressive behavior. Recurrence is usual, occurring principally in the first 2 years after operation. Recurrence rate was found to vary from 25% to 60%, depending on the kind of treatment management and followup period. The odontogenic keratocyst is a histologically distinct lesion that is thought to arise from dental lamina remains, usually occurring in the posterior portion of the mandible or the mandibular ramus. Odontogenic keratocyst occurrence in the maxilla is unusual and its appearance in the maxillary sinus is very uncommon. Recently, we experienced a case of odontogenic keratocyst in the maxillary sinus that presented as nasal obstruction in a 23-year-old female. An enucleation was performed and there has been no evidence of recurrence up to 6 months following the surgery.
