She is innocent, honest, kindhearted, etc. She has great consciousness of self-esteem and pride. Among all, Tess is pure and has noble spirit of self-sacrifice and devotion. Suffering successive setbacks, Tess still dreams of happiness and keeps loyal to her love. In her pure heart, the longing for goodness never stops or dies.展开更多

The tongue locates forward and is larger than normal in prognathism, in which the jaw protrudes from the skull. It is not clear whether an enlarged tongue causes the open bite, protrusion or dental arch misalignment, or is a result of them. Here, we report two patients with mandibular prognathism and relative macroglossia, which were treated by mandibular setback surgery using a bilateral sagittal split osteotomy (BSSO) and excision of the tongue. This procedure achieved aesthetic improvement of the face and dentition.展开更多
