title: Simple techniques for three-dimensional photography of the nose in nasal deformity.
abstract: OBJECTIVE
  To investigate the use of anaglyphs and stereograms for three-dimensional imaging of the external nose.
  
  
  METHODS
  Red-cyan anaglyphs and colour stereograms created from stereo photographs of patients with nasal deformity were compared to standard photographs. Assessors rated images on 'life-likeness' of imaging, contour definition and utility for surgical planning.
  
  
  RESULTS
  9 patients were recruited. Stereograms provided significantly improved life-like features and definition of nasal structure, with some benefit for pre-operative planning. Less benefit was found for anaglyph images. Oblique views proved most effective.
  
  
  CONCLUSIONS
  Stereograms provide simple, inexpensive three-dimensional images of the nose, with potential uses in operative analysis, medicolegal documentation, teaching and research.
