Maxillary sinusitis are common infections. A dental origin is found in about 10% of the cases. The roots of the posterior maxillary teeth are adjacent to the sinus floor. Extensions of dental infections are therefore possible to the sinus. An odontogenic source should be considered in patients with a history of dental pain or recent oral surgery and those with extended unilateral sinusitis or unilateral sinusitis resistant to conventional treatment. Maxillary sinusitis of dental origin are polymicrobial infections. Conventional radiographs and CT-scans are required for the diagnosis and proper management. Dental treatments to remove the underlying cause combined with oral antibiotics to treat the infection are required. Endoscopic or open surgery may be necessary to complete the treatment and restore adequate sinusal function.
上颌窦炎是常见的感染性疾病。约10%的病例病因源于牙齿。上颌后牙的牙根毗邻鼻窦底部，因此牙齿感染有可能蔓延至鼻窦。对于有牙痛病史或近期口腔手术史的患者，以及患有单侧鼻窦炎且病情迁延或对传统治疗耐药的患者，应考虑牙源性病因。牙源性上颌窦炎属于混合性感染。诊断和恰当治疗需要借助传统X线片和CT扫描。需要进行牙科治疗以消除潜在病因，并联合口服抗生素治疗感染。可能需要借助内镜手术或开放手术来完成治疗并恢复鼻窦的正常功能。
