Surgical anatomy of the nose

Abstract

Assessing the external nose requires an understanding of the anatomic components that contribute to its normal topographic features. Structures that influence the external appearance include the skin, which varies in thickness, and the underlying bony/cartilaginous skeletal framework. The soft tissue covering of the nose, external blood supply, external sensory nerve supply, caudal third of the nose, internal anatomy of the nose, and the boney vault are described. The authors conclude that knowing the details of nasal anatomy is essential when undertaking rhinoplasty surgery. Careful study of these details makes for a more confident, prepared practitioner.
