Type : Other, mainly phenotypes with suspected mendelian basis;
Alternative titles and symbols : Facial asymmetry; Hemifacial hypertrophy; Facial hemihypertrophy;
Description : The criteria for the hemifacial type of congenital hypertrophy are (1) unilateral
enlargement of the viscerocranium bounded superiorly by the frontal bone (not including
the eye), inferiorly by the inferior border of the mandible, medially by the midline
of the face, and laterally by the ear, the pinna being included within the hypertropic
area, and (2) enlargement of all tissues--teeth, bone, and soft tissue--within this
area (Rowe, 1962).;
