Consisting of the paired nasal bones and the ascending frontal process of the maxilla, the vault acts as a cantilever, supporting the upper nose and the upper lateral cartilages. 骨性穹隆由一對鼻骨和上頜骨額突構成，好似一個(gè)支架，支撐著(zhù)鼻上部和上外側軟骨。
A transition zone of bony thickness exists along the frontal processes of the maxilla from the piriform aperture to the radix along the lateral nasal wall. 在上頜骨額突從梨狀孔向鼻根沿鼻腔外側壁走行過(guò)程中存在著(zhù)一骨厚度移行區。
