A 66-year-old woman presented with a 6-month history of unilateral right nasal obstruction and rhinorrhoea not responding to medical therapy. She had a history of dental implantation for an unerupted tooth on the right side 3 years ago. Physical examination including flexible nasendoscopy demonstrated yellow debris in the right middle meatus. CT paranasal sinuses demonstrated a radiopaque lesion in the right anterior ethmoid sinus and resembled the unerupted tooth. The tooth was removed endoscopically from the right nasal cavity without complications. This case highlights the importance of eliciting an accurate dental history and considering ectopic dentition as a differential diagnosis in a patient with unilateral symptoms of sinusitis.
一位 66 岁女性，因右侧单鼻孔阻塞伴流涕 6 个月就诊，经药物治疗后未见缓解。3 年前，该患者因右侧未萌出牙行牙种植术。体格检查包括鼻内镜检查，右侧中鼻道可见黄色碎片。鼻窦 CT 显示右侧额窦前份有不透射线的病变，类似于未萌出牙。该牙经鼻内镜从右侧鼻腔取出，无并发症。本病例强调了在单侧鼻窦炎患者中，详细询问牙科病史和考虑异位牙作为鉴别诊断的重要性。
