Growth of Maxilla in Patients with Cleft Lip and Palate -Compared with various methods of Treatment for Cleft Palate-

研究了婴幼儿至8岁唇腭裂患者在不同的腭裂成形术后上颌生长情况。研究对象为201例唇腭裂患者。采用上颌连续铸型（901张）和x线头片（624张）进行分析比较。腭成形术的分类系统为粘骨膜瓣、改良的粘骨膜上粘膜瓣和两期腭成形术联合Hotz板。实验结果如下：1.实验结果表明：采用Hotz钢板生长引导，观察上颌前段生长和外侧节段前外侧生长情况。两期腭成形术联合Hotz板组与其他组相比，上颌前突和宽度在8岁时明显增长。3 .侧位x线图分析显示，两期腭成形术联合Hotz板组与粘骨膜瓣组相比，SNA和A′-Ptm的位置显著。结论两期腭成形术联合霍氏板组对腭裂患者上颌生长是有效的。

The maxillary growth in patients with cleft lip and palate from infancy to eight years of age following various methods of palatoplasty was studied. The subjects consisted of 201 cleft lip and palate patients. Serial maxillary casts (901) and roentgenographic cephalograms (624) were used for the analysis and compared. The classification system of palatoplasty was mucoperiosteal flap, modified supraperiosteal mucosal flap and two-stage palatoplasty combined with Hotz plate.The results were as follows :1.Anterior growth of maxilla and anterolateral growth of lateral segments were observed by growth guidance of Hotz plate.2.The signigicant anterior and width growth of maxilla were observed to eight years of age in two-stage palatoplasty combined with Hotz plate group compared with other groups.3.The analysis of lateral roentgenographic cephalograms revealed that the significant position of SNA and A'-Ptm in two-stage palatoplasty combined with Hotz plate group compared with mucoperiosteal flap group.4.It is conclueded that two-stage palatoplasty combined with Hotz plate group is effective for maxillary growth in patients with cleft lip and palate.
