“…Both jaws were retrognathic, even though maxillary and mandibular body average length increased under the influence of GH therapy. These results are in accordance with previous studies that have also found retrognathic jaws [24][25][26] and increase in mandibular ramus [24][25][26] and corpus lengths 25,26 in TS girls treated with GH. Bimaxillar retrognathism, also present in TS girls 2,3,5-7 and adult patients 4,8 that were not treated with GH, used to be explained by flattened cranial base 3 and reduced lengths of maxilla and mandible.…”
