Because this produces peculiar tooth jaw face to misshape, constant expression is mid development undesirable reach cave, length of direction of around of bone of the upper jaw and perpendicular direction height shorten, tooth bend is narrow, the tooth lists jam, occlusive relation is disorder, anterior teeth or complete tooth bend are enclothed instead, before mandible true sex or false sex dash forward. 2 use DO method at the back of art of Jiao Zhi cleft palate in the portion caves at the back of art of abnormal cleft palate in the portion caves abnormal treatment method is very much, if Kettle reports block is mental,raise fight a way, the face guard method that Tind Lund uses, wang Ketao [1] uses Peng body to get together 4 fluorine ethylene fills up repair misshapes this kind etc.

因此产生特有的牙颌面畸形，常表现为面中部发育不良及凹陷，上颌骨前后方向长度及垂直方向高度变短，牙弓狭窄，牙列拥挤，咬合关系紊乱，前牙或全牙弓反覆盖，下颌真性或假性前突。2利用DO术矫治腭裂术后面中份凹陷畸形腭裂术后面中份凹陷畸形治疗方法很多，如Kettle报道枕颏支抗法，Tind lund采用的面罩法，王克涛[1]采用膨体聚四氟乙烯充填修复此类畸形等。
