1. A method of assessing nasal symmetry, the method comprising:
employing a surface scanning device to acquire facial surface data of a facial region of a subject, the facial region including a nose of the subject;
processing the facial surface data to determine a nasal deviation measure indicative of a lateral deviation between a nasal midline of the subject and a facial midplane of the subject;
processing the facial surface data to determine a nasal symmetry measure indicative of a degree of symmetry associated with a nasal surface region relative to the facial midplane; and
generating a display comprising nasal deviation and symmetry information, the nasal deviation and symmetry information being generated based on both the nasal deviation measure and the nasal symmetry measure.
