This questionnaire-based study investigated the psychological profile of or
thognathic patients prior to starting treatment and compared the findings w
ith a control group of non-patients. Comparison of the data used multivaria
te multiple regression analysis where outcome variables and independent var
iables were studied simultaneously. Some differences were found in the psyc
hological profile of the orthognathic patient. They displayed higher levels
of state anxiety (P < 0.001), higher numbers of individuals in their socia
l support network (P < 0.05), and lower body image and facial body image (P
< 0.001). Self-esteem was also found to be lower, but only at borderline l
evels of significance (P= 0.052).
