Rhinoplasty: nasal anatomy.

On the basis of over 100 fresh cadaver dissections as well as a review of nasal embryology and development, several important observations can be made regarding surgical anatomy of the nose. Within the bony vault, nasal profile modification consists of two distinct maneuvers: bony hump removal and modification of the nasofrontal groove area. The cartilaginous vault is in reality a unified, winged structure composed of septum and upper lateral cartilages. Within the nasal lobule, a continuous cartilaginous ring exists. The nose itself is covered by a superficial muscular aponenotic system.
