目的：为上颌骨移位术提供解剖学依据。方法：选用２１例切割为不同切面的成人头部断面和１０例头部正中矢状剖面标本。结果：上颌窦由５个壁构成，内侧壁呈垂直形的骨板；后外侧壁是由前外行向后内侧方向的壁；前壁上壁几乎呈方板状；下壁由牙槽突上缘和后外侧壁的下部组成。后外侧壁外侧分布有一层脂肪组织，厚度为５．６～６．４ｍｍ。结论：保留内侧壁或下壁的上颌窦移位术应以牙槽弓为切开的标志；保留下壁及硬腭的手术，应注意对翼腭窝血管、神经的保护。
Objective: To provide anatomical basis for maxillary transposition. Methods: Twenty-one adult head sections and 10 cases of median sagittal section were selected. Results: The maxillary sinus consisted of 5 walls, the medial wall was perpendicular to the bone plate, the posterior lateral wall was anteriorly medial to posterior medial wall, the anterior wall was almost square plate, and the inferior wall was composed of alveolar process Edge and the outer wall composed of the lower part. Outside the outer wall of the distribution of a layer of fat tissue, a thickness of 5.6 ~ 6.4mm. CONCLUSIONS: The maxillary sinus displacement that preserves the medial wall or inferior wall should be marked by the alveolar arch as a cut-off. To preserve the inferior wall and the hard palate, attention should be paid to the protection of the veins and nerves of the pterygopalatine fossa.
