Serial cadaver dissections were performed and the anatomy of the natural ostium of the maxillary sinus and its adjacent structures observed. The results showed obvious anatomic variations. In most cases, the maxillary ostium was located in the infundibulum, directly under the orbit. The average distance was 1.1 cm from the maxillary ostium to the anterior maxillary wall, showing the anatomic relationship of the maxillary ostium with the nasolacrimal duct. The close anatomic relationship between the antronasal channel and orbit was demonstrated by radiography. A retrospective review of 70 middle meatal antrostomies was conducted and discussed. The anatomy of the antronasal channel should be well understood by an endoscope sinus surgeon in order to perform the middle meatal antrostomy without injuring the orbit and nasolacrimal duct.
进行了系列尸体解剖，并观察了上颌窦自然开口及其相邻结构的解剖情况。结果显示存在明显的解剖变异。在大多数情况下，上颌窦开口位于漏斗部，直接位于眼眶下方。上颌窦开口至上颌前壁的平均距离为1.1厘米，显示了上颌窦开口与鼻泪管的解剖关系。通过影像学检查证实了鼻上颌通道与眼眶之间紧密的解剖关系。对70例中鼻道上颌窦造口术进行了回顾性分析并进行了讨论。鼻窦内窥镜外科医生应充分了解鼻上颌通道的解剖结构，以便在进行中鼻道上颌窦造口术时不损伤眼眶和鼻泪管。
