Assured of a robust blood supply by its narrow pedicle centered on the septal branch of the superior labial artery, the pivoting septal flap provides nasal support from the radix to the most distal nasal tip and from the tip to the columella base--plus a large bonus of lining tissues for the nasal vault and vestibules. Lining flaps from such intranasal tissues are thin, vascular, and flexible. They allow the use of primary cartilage grafts and the establishment of a subsurface architecture in the shape of a nose. When visualized through a conforming forehead flap, the normal landmarks and highlights are restored. In cases of total nasal amputation, a pivoting septal flap permits the fabrication of dorsal nasal support weeks before lining and cover flaps are assembled.
以唇上动脉鼻中隔支为中心的狭窄蒂确保了充足的血供,旋转鼻中隔瓣为从鼻根到最远端鼻尖以及从鼻尖到鼻小柱基部提供了鼻支撑——此外还为鼻穹窿和前庭提供了大量的衬里组织。来自此类鼻内组织的衬里瓣薄、血管丰富且柔韧。它们允许使用原发性软骨移植,并建立鼻形的皮下结构。通过贴合的额瓣观察时,正常的标志和突出部分得以恢复。在全鼻切除的病例中,旋转鼻中隔瓣允许在组装衬里瓣和覆盖瓣之前数周制作鼻背支撑结构。
