我们报告一个因拔牙后假牙衬料经由口腔窦瘘管进入而造成慢性上颌窦炎的病例。患者是一位80岁的女性，她来我们这里就诊，主诉右侧后上颌骨有脓性分泌物。她拔除了右上第二磨牙，并用硅胶衬里材料重新衬上义齿。患者在第一次来我诊所就诊前20天发现右脸颊肿胀和脓性溢液。口腔检查显示右上颌骨后牙槽嵴有一直径3 mm的口腔窦瘘。计算机断层扫描显示在右侧上颌窦内有一个高密度异物，粘膜衬里增厚。在异物引起的上颌窦炎的诊断下，内窥镜上颌窦手术与异物取出同时进行。取出的异物大小为12 × 6 mm，椭圆形，颜色为浅粉色，与硅胶义齿衬里材料相容。在随访期间，观察到口腔窦瘘在异物取出后自发闭合。术后7个月上颌窦形态良好，无鼻窦炎复发。
We report a case of chronic maxillary sinusitis caused by denture lining material entering through an oroantral fistula after tooth extraction. The patient was an 80-year-old female who visited us with a complaint of pus discharge from the right posterior maxilla. She had extraction of the upper right second molar and had her upper denture relined with silicone lining material. The patient noticed swelling of the right cheek and purulent rhinorrhea 20 days before her first visit to our clinic. Oral examination showed an oroantral fistula with a diameter of 3 mm in the posterior alveolar ridge of the right maxilla. Computed tomography revealed a hyperdense foreign body in the right maxillary sinus and thickening of the mucosal lining. Under diagnosis of maxillary sinusitis caused by a foreign body, endoscopic maxillary surgery was performed simultaneously with the removal of the foreign body. The foreign body removed was 12 × 6 mm in size, oval in shape, light pink in color, and compatible with silicone denture lining material. During the follow-up it was observed that the oroantral fistula closed spontaneously after the removal of the foreign body. The maxillary sinus was in a good shape without recurrence of sinusitis seven months after surgery.
