Large Keratocystic Odontogenic Tumor involving entire maxillary sinus: A common pathology in uncommon location

Keratocystic odontogenic tumor (KOT) is an odontogenic neoplasm of jaw which occurs more frequently in mandible. Its occurrence in maxilla is relatively infrequent. This article reports a case of large KOT of left maxilla involving the entire maxillary sinus extending up to the infra-orbital rim, in a middle aged person. The pathology was treated with surgical enucleation and chemical cauterization. Taking into the consideration the high recurrence rate of KOT, regular and periodic follow up is necessary in such cases. At 2 years follow up the present case showed normal healing with no recurrence.
