case_images: The upper midline was co-incident with facial midline [Figure 1]. Hehad a nasolabial angle (110 ), retrusive upper lip (UL-E line = -3 mm) and protrusive lower lip (LL-E line = 3.9 mm) [Figure 4b, Table 1]. Antero posterior bite was corrected, and positive overjet was achieved [Figures 6-8 and Table 1]. Mandible was slightly rotated downwards and backward with change in FMA from 23.6  to 28  [Figure 15 and Table 1].

case_images: Screening of orthopantomogram (OPG) radiograph showed normal condyle glenoid fossa relationship [Figure 4a]. Hehad a nasolabial angle (110 ), retrusive upper lip (UL-E line = -3 mm) and protrusive lower lip (LL-E line = 3.9 mm) [Figure 4b, Table 1]. Postero-anterior cephalogram revealed no gross asymmetry but showed skeletal constriction of maxilla (J-J/Ag-Ag = 74%) [Figure 4c].
