Definition of outcome variables

Outcome variables	Definition
Skeletal symmetry	Linear and angular measurements of the anatomic landmarks of the facial skeleton using radiographs for assessment of facial asymmetry
Menton deviation	Distance from the menton of the mandible to the midsagittal reference plane
Maxillary canting	Angle between the maxillary plane and the horizontal reference plane
Frontal ramal inclination*	Angle between the midsagittal reference line and the line connecting the most lateral point of the condylar head and gonion in the frontal plane
Ramus height*	Distance from the condylion to gonion
Body length*	Distance from the gonion to menton
Midline discrepancies	Deviation of upper and lower dental midline from the midsagittal reference line; midline discrepancy between the upper and the lower dentition
Lip canting	The angle between the line where the upper and lower lips meet and the horizontal reference line
TMD	Signs and symptoms related to TMD
Quality of life	Quality of life related to surgical treatment of facial asymmetry
Relapse	Change of more than 1 mm in the menton deviation after surgery

TMD, temporomandibular disorders.
