Combined 3-dimensional and mirror-image analysis for the diagnosis of asymmetry.

Three-dimensional imaging techniques have greatly improved our ability to assess asymmetry by means of linear and angular measurements. However, visualizing deformities enables a unique appreciation of the underlying deformity, which might not be possible by looking at quantitative numbers alone. This article describes the method of a mirror-image analysis technique to visualize the asymmetry to assist in diagnosis and treatment planning. Other advantages of a mirror-image analysis, in addition to the quantitative analysis, are also discussed.
