Normal variations in the paranasal sinus region are well documented in literature. We present five cases of a little known normal variant, which can have serious implications for the patient as well as the operating surgeon. An ectopic infra orbital nerve canal coursing through the maxillary sinus has rarely been described in imaging literature. This may sometimes be mistaken for a simple septum in the maxillary sinus and may cause serious complications during Functional Endoscopic sinus surgery (FESS) surgeries. We describe the imaging findings and present a brief review of the previous publications on the same subject.
鼻窦区域的正常变异在文献中有充分记载。我们展示了五例鲜为人知的正常变异病例，这对患者以及手术医生都可能产生严重影响。一条异位眶下神经管穿过上颌窦，在影像学文献中鲜有描述。这有时可能被误认为是上颌窦内的一个简单间隔，并且在功能性鼻内镜鼻窦手术（FESS）中可能导致严重并发症。我们描述了影像学表现，并对之前关于同一主题的出版物进行了简要综述。
