Subjects were divided into 3 groups: maxillary advancement\u2010only (AO), maxillary advancement\u00a0+\u00a0impaction (AI) and maxillary advancement\u00a0+\u00a0downfracture (AD). Exclusion criteria were mandibular\u2010only surgery, occlusal canting, facial asymmetry, orbital surgery and craniofacial syndrome. One investigator measured inferior scleral exposure on both sides using following landmarks: upper eyelid margin (A), inferior limbus (B) and lower eyelid margin (C). Distance between A and C was recorded as overall eye height (E), and distance between B and C was recorded as inferior sclera exposure (S). S:E ratio in percentage was calculated to standardize sclera exposure relative to overall eye height.
