Abstract

We report a case of keratocystic odontogenic tumor (KCOT) in a 21-year-old female patient. The patient was referred to our clinic from a dental clinic for the radical treatment of recurrent KCOT in the maxilla. She had undergone conservative drainage surgery twice at that clinic. The tumor was cystic and covered with a bony capsule, which extended high into the maxillary sinus. A pinhole fistula, which was created during a previous surgery, was identified in the gingivobuccal sulcus. The whole tumor was successfully removed using a bidirectional approach from the fistula and from the antrostomy in the middle meatus. This report shows that the intimate collaboration between an otorhinolaryngologist and an oral surgeon could provide a minimally invasive, and at the same time, radical surgical treatment for certain kinds of tumor in the head and neck region. We also recommend the introduction of endoscopic surgeries by the oral surgeon.
