Foreign bodies in paranasal sinuses are very rare and most of them are encountered in the maxillary sinus. These foreign bodies may be organic or inorganic and can enter the maxillary sinus through an oro-antral fistula. The oro-antral fistula is formed by a break in the bony segment of the maxillary sinus floor and usually arises subsequent to maxillary premolar and molar extractions. A 63-year-old female patient evaluated for a nonhealing, left, toothless palate lesion and chronic headache occurring over 4 years. Radiography and computed tomography revealed bone discontinuity in the left floor of the maxillary sinus and calcifications within the antrum. A blue foreign body, later identified as dental impression material, was removed by intranasal endoscopy. A careful oral examination is recommended prior to prosthetic restorations. In addition, paranasal sinus foreign bodies should be surgically removed to prevent secondary soft tissue reactions.
鼻窦异物非常罕见，其中大多数见于上颌窦。这些异物可能是有机的或无机的，可通过口鼻瘘进入上颌窦。口鼻瘘由上颌窦底骨段的破损形成，通常发生在上颌前磨牙和磨牙拔除之后。一名63岁女性患者，因左侧无牙腭部病变不愈合及4年多来的慢性头痛前来就诊。影像学检查和计算机断层扫描显示上颌窦左侧底部骨质连续性中断，窦腔内有钙化。通过鼻内镜取出了一个蓝色异物，后来确定为牙科印模材料。建议在进行修复修复之前进行仔细的口腔检查。此外，鼻窦异物应手术取出，以防止继发软组织反应。
