Paranasal sinus anatomy and variations have gained interest with the introduction of functional endoscopic sinus surgery and the concept of the ostiomeatal complex. Anatomical variations can be divided in structural abnormalities, (increased) pneumatization and supplementary openings. Most anatomical variations are equally found in control and sinusitis patients. The anatomical variations which are most commonly associated with sinus pathology are septal deviations, true conchae bullosae and supplementary maxillary ostia but the latter one only when recycling is present. The knowledge of anatomical variations is most important in the surgical management and specifically in the prevention of complications.
随着功能性鼻内镜鼻窦手术的引入以及窦口鼻道复合体概念的提出，鼻窦解剖结构及其变异受到了关注。解剖变异可分为结构异常、（过度）气化和副开口。大多数解剖变异在对照组和鼻窦炎患者中同样常见。与鼻窦病变最常相关的解剖变异是鼻中隔偏曲、真正的泡状鼻甲和副上颌窦口，但只有在存在引流不畅时才会出现后者。解剖变异的知识在手术管理中，特别是在预防并发症方面最为重要。
