Odontogenic keratocysts need not only to be fenestrated, but also removed completely. The cysts show a high rate of recurrence and occasionally show malignant transformation. Herein, we report a case of odontogenic keratocyst in which we performed endoscopic modified medial maxillectomy (EMMM) for complete removal of the cyst. The patient was a 65-year-old female who was diagnosed as having an odontogenic keratocyst by sinus CT and MRI, and was treated by EMMM for complete removal of the cyst under a bright field. She had a good postoperative course and the condition of her sinus mucosa returned to normal.
Until now, EMMM has been used mainly for the treatment of papillomas, however, we believe that it is also useful for the treatment of odontogenic keratocysts. In conclusion, we suggest that this endoscopic procedure is effective for obtaining direct and wide access into the maxillary sinus to accomplish complete removal of maxillary odontogenic keratocysts.
