The Odontogenic Keratocyst (OKC) is one of the most aggressive odontogenic cysts. OKCs of the maxilla are particularly rare with less than 1% of cases reported in the literature. A 29-year-old female patient presented with pain and loose upper molars. Imaging confirmed an ectopic tooth at the osteomeatal complex and a maxillary OKC. These were endoscopically surgically removed and two teeth were encountered at the maxillary antrum. Histopathology confirmed the diagnosis of OKC of the maxilla. Surveillance with CT imaging and clinical assessment at 6 months shows no evidence of recurrence.
牙源性角化囊肿（OKC）是最具侵袭性的牙源性囊肿之一。上颌骨的OKC极为罕见，文献报道的病例不到1%。一名29岁女性患者出现疼痛和上颌磨牙松动。影像学检查证实鼻窦复合体处有一颗异位牙以及一个上颌骨OKC。通过内镜手术将其切除，在上颌窦内发现了两颗牙齿。组织病理学检查确诊为上颌骨OKC。6个月时通过CT成像监测和临床评估未发现复发迹象。
