Iatrogenic foreign bodies of dental origin are rare and frequently involve the maxillary sinuses. We report an unusual case of tooth-root migration into the ethmoid sinus after dental extraction. A 54-year-old woman with a history of maxillary left molar extraction 6 months prior presented with symptoms of left nasal obstruction, green malodorous nasal discharge, hyposmia, and left-sided facial pressure for 3 months. She was diagnosed with unilateral sinusitis, and nasal endoscopy revealed severe left middle meatus edema with thick pus discharge. Computed tomography of the paranasal sinuses revealed a radiopaque foreign body in the left anterior ethmoid sinus with complete opacification of the left paranasal sinuses. The tooth root was extracted transnasally via functional endoscopic sinus surgery. Complete symptom resolution was achieved postoperatively. Sinonasal foreign bodies can cause sinusitis owing to mucosal irritation. Endoscopic extraction is an optimal treatment owing to its short operative time and reduced perioperative morbidity.
医源性牙科源性异物很少见，且常累及上颌窦。我们报告了一例拔牙后牙根迁移至筛窦的罕见病例。一名54岁女性，6个月前有左上磨牙拔牙史，出现左侧鼻塞、绿色恶臭鼻分泌物、嗅觉减退和左侧面部压迫感3个月。她被诊断为单侧鼻窦炎，鼻内镜检查显示左侧中鼻道严重水肿，有浓稠脓性分泌物。鼻窦计算机断层扫描显示左前筛窦有一个不透射线的异物，左侧鼻窦完全浑浊。通过功能性鼻内镜鼻窦手术经鼻取出牙根。术后症状完全缓解。鼻窦异物可因黏膜刺激导致鼻窦炎。内镜下取出术因其手术时间短和围手术期发病率低，是一种最佳治疗方法。
