Abstract： Objective  This study researched the effects of myofunctional training therapy to Class Ⅱ1mandibular retrognathia patients，and the effect of the myofunctional training on these cases was discussed in detail. Methods 10 patients who were all Class Ⅱ1mandibular retrognathia during growth were selected. Their age was during 8 to 10. They all accepted myofunctional training therapy. They were photographed cephalometric X-ray pretherapy and post-treatment. Hard tissue was analyzed by cephalometric X-ray. 22 indicators of hard tissue profile were gathered. Results Cephalometric measurement showed that： after myofunctional training the distance of Ar-Go and Go-Me increased. The angle of SNB also increased and the angle of ANB and NA-PA decreased（P
