Oroantral communication is an unnatural communication of the maxillary sinus with the oral cavity, often resulting from dental extractions, infection, trauma, or excision of cysts or tumors. Pathological epithelialization of oroantral communication leads to oroantral fistula. Various techniques have been proposed for surgical closure. Uneventful healing of the defect can be achieved in the absence of antral infection. Hence, medical management of maxillary sinusitis should precede surgical closure of the defect. Here, we report a case of an oroantral fistula of the left maxillary third molar, caused by a secondary infection of the extraction site, managed primarily by antibiotics, topical steroids, and irrigating agents followed by surgical closure. It is essential to carefully inspect the post-extraction socket of maxillary teeth due to its high risk of development of oroantral communication. Also, the management of oroantral communications needs early detection to prevent infection and to prevent transforming into an oroantral fistula. In case of an infected oroantral communication or fistula, priority rests on treating the infection first and followed by surgical repair.
口腔上颌窦交通是上颌窦与口腔之间的异常连通，通常由拔牙、感染、外伤或囊肿或肿瘤切除引起。口腔上颌窦交通的病理性上皮化会导致口腔上颌窦瘘。已经提出了各种手术闭合技术。在没有窦腔感染的情况下，缺损可以顺利愈合。因此，在上颌窦炎的手术闭合之前，应先进行药物治疗。在此，我们报告一例因拔牙部位继发感染导致的左上颌第三磨牙口腔上颌窦瘘病例，主要通过抗生素、局部类固醇和冲洗剂进行治疗，随后进行手术闭合。由于上颌牙齿拔牙窝发生口腔上颌窦交通的风险较高，因此必须仔细检查拔牙后的牙槽窝。此外，口腔上颌窦交通的处理需要早期发现，以预防感染并防止转变为口腔上颌窦瘘。对于感染的口腔上颌窦交通或瘘，首先要优先治疗感染，然后再进行手术修复。
