This nose was missing some of its middle section, along the dorsum.  I reconstructed it by placing an artificial material in the depression.

There are many materials that can be used successfully to build up part of the nose.  Some of the materials are natural (the patient's own bone or cartilage, stolen from another part of the body), and some are artificial.  I generally prefer the artificial materials, at least today, for several reasons.  One of the most important reasons is that a soft, artificial material can sit in the nose without showing a sharp edge or corner.  Smoother materials can make the nose look more natural.
