Odontogenic maxillary sinusitis (OMS) is a subtype of maxillary sinusitis (MS). It is actually inflammation of the maxillary sinus that secondary to adjacent infectious maxillary dental lesion. Due to the lack of unique clinical features, OMS is difficult to distinguish from other types of rhinosinusitis. Besides, the characteristic infectious pathogeny of OMS makes it is resistant to conventional therapies of rhinosinusitis. Its current diagnosis and treatment are thus facing great difficulties. The multi-disciplinary cooperation between otolaryngologists and dentists is absolutely urgent to settle these questions and to acquire standardized diagnostic and treatment regimen for OMS. However, this disease has actually received little attention and has been underrepresented by relatively low publication volume and quality. Based on systematically reviewed literature and practical experiences of expert members, our consensus focuses on characteristics, symptoms, classification and diagnosis of OMS, and further put forward multi-disciplinary treatment decisions for OMS, as well as the common treatment complications and relative managements. This consensus aims to increase attention to OMS, and optimize the clinical diagnosis and decision-making of OMS, which finally provides evidence-based options for OMS clinical management.

牙源性上颌窦炎（OMS）是上颌窦炎（MS）的一种亚型。它实际上是继发于邻近的上颌牙感染性病变的上颌窦炎症。由于缺乏独特的临床特征，OMS 很难与其他类型的鼻窦炎区分开来。此外，OMS特有的传染性病原体使其对鼻窦炎的常规疗法具有抵抗力。目前其诊断和治疗面临着很大的困难。耳鼻喉科医生和牙科医生之间的多学科合作绝对迫切需要解决这些问题并获得标准化的OMS诊断和治疗方案。然而，这种疾病实际上很少受到关注，并且由于发表数量和质量相对较低而未被充分报道。在系统回顾文献和专家成员实践经验的基础上，我们的共识重点关注OMS的特征、症状、分类和诊断，并进一步提出OMS的多学科治疗决策，以及常见的治疗并发症和相关管理。该共识旨在提高对OMS的关注，优化OMS的临床诊断和决策，最终为OMS临床管理提供循证选择。
