The space lay be-tween the periosteum, perichondrium and the fascia dorsum nasi. The shape of the space is like a pyramid. The space averaged 3.09 ± 0.66 cm in length. 此间隙位于鼻骨膜、软骨膜与鼻背筋膜之间,间隙上窄、下宽呈锥状,全长平均为3.09±0.66cm。
Results: ⑴ A latent space between the periosteum and the connective tissue lay under the fascia of dorsum nasi. 结果:⑴在鼻背筋膜下存在一薄的疏松结缔组织层,与骨膜之间为一潜在间隙。
