Abstract：
Introduction: Ectopic foreign bodies in the maxillary sinus occur rarely. Ectopic tooth eruption rarely occurs in the orbit, nasal cavity, maxillary sinus, and elsewhere. Ectopic eruption of teeth in the maxillary sinus is most commonly associated with wisdom teeth and is rarely associated with supernumerary teeth. This rare phenomenon may be accompanied by chronic recurrent sinusitis with headaches and facial pain. However, fibro-osseous lesions in the paranasal sinuses are discovered incidentally on X-ray images and are often asymptomatic. Osteoma is the most common fibro-osseous lesion that develops in the paranasal and nasal sinuses. Osteomas rarely cause serious symptoms such as orbital lesions and intracranial invasion. Case Presentation: We report a rare case of exostosis containing supernumerary teeth within the maxillary sinus. A characteristic pedicled bone lesion with a clear border on computed tomography was the undefined orthopantomogram radiopacity in the maxillary sinus, and the lesion contained supernumerary teeth. As the patient had chronic nasal congestion, the tumor was surgically removed. Pathologically, the surgical specimen revealed an osteoma. The patient\'s symptoms of chronic sinusitis disappeared. Because the patient had no history of midface trauma or surgery, the supernumerary teeth were speculated to have migrated during a reactive osteogenic process caused by chronic sinusitis. Conclusions: A foreign body in the maxillary sinus can be easily diagnosed by computed tomography. Surgical removal is recommended if the foreign body is symptomatic or occupies more than half of the maxillary sinus. This can help resolve chronic sinusitis symptoms and prevent serious complications in the future.
摘要：
简介：上颌窦异位异物很少发生。异位牙萌出很少发生在眼眶，鼻腔,上颌窦,和其他地方。上颌窦中牙齿的异位萌出最常见的是与智齿有关，很少与多余的牙齿有关。这种罕见的现象可能伴有慢性复发性鼻窦炎，伴有头痛和面部疼痛。然而,鼻旁窦的纤维骨性病变是在X射线图像上偶然发现的，通常无症状。骨瘤是在鼻旁窦和鼻窦发展的最常见的纤维骨病变。骨瘤很少引起严重症状，如眼眶病变和颅内侵犯。病例介绍：我们报告了一例罕见的上颌窦内含有多生牙的外生体。在计算机断层扫描上具有清晰边界的特征性带蒂骨病变是上颌窦中未定义的正骨图射线不透性，病变包含多余的牙齿。由于病人有慢性鼻塞,手术切除了肿瘤.病理上,手术标本显示骨瘤。患者的慢性鼻窦炎症状消失。因为病人没有面部创伤或手术史，推测多余的牙齿在慢性鼻窦炎引起的反应性成骨过程中迁移。结论：上颌窦异物可通过计算机断层扫描轻松诊断。如果异物有症状或占据上颌窦的一半以上，建议手术切除。这可以帮助解决慢性鼻窦炎症状并防止将来发生严重的并发症。
