Abstract：
Recurrent rhinorrhoea that occurs chronically, needs to consider the possibility of a fistula in the nasal cavity, which has the potential to form a rhinolith. We report the case of a 39-year-old man with complaints of recurrent rhinorrhoea since four years ago, accompanied by thick secretions, symptoms of post-nasal drips, and olfactory disturbances. The patient had a history of removing the left upper molar (molar I), which causes a fistula in the tooth extraction site, making it more likely for food and drink to enter the left nasal cavity. Anterior rhinoscopy examination revealed a white mass in the left inferior meatus and a purulent odour discharge. In addition, there were gingival defects of the first molar teeth, multi-sinusitis, and nasal septum deviation. Rinolith extraction was performed using functional endoscopic sinus surgery, submucosal resection, and repair of gingivo-nasal defects with rotational flaps. Follow-up for one week showed that the flap was in place and there were no complications.
摘要：
反复发作的慢性鼻漏，需要考虑鼻腔内瘘管的可能性，有可能形成鼻石。我们报告了一名39岁的男子，自四年前以来，他一直抱怨反复发作。伴随着浓稠的分泌物，鼻后滴水的症状，和嗅觉紊乱。患者有切除左上磨牙（磨牙I）的病史，导致拔牙部位的瘘管，使食物和饮料更有可能进入左鼻腔。前鼻镜检查显示左下鼻道有白色肿块和脓性气味。此外,第一磨牙有牙龈缺损,多鼻窦炎,和鼻中隔偏曲.使用功能性内窥镜鼻窦手术进行了Rinolith摘除术，粘膜下切除术,用旋转皮瓣修复牙龈鼻缺损。随访1周,皮瓣到位,无并发症发生。
