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

本文研究了唇腭裂患者从婴儿期到8岁的上颌骨发育情况。受试者包括201例唇腭裂患者。采用上颌骨连续铸型(901例)和头颅X线片(624例)进行分析比较。腭裂成形术的分类系统为粘骨膜瓣，改良骨膜上黏膜瓣联合二期腭裂联合Hotz钢板组，结果如下：1.在Hotz平板生长指导下，观察到上颌骨前向生长和侧方生长；2.二期腭裂联合Hotz钢板组在8岁时上颌骨前部和宽度较其他组显著增长；3.侧位X线片分析显示，二期腭裂联合Hotz钢板组与粘膜骨膜瓣组相比，SNA和A‘-PTM的位置有显著差异。4.结论：二期腭裂联合Hotz钢板组与粘膜骨膜瓣组相比，两期腭裂联合Hotz钢板组上颌骨前部和宽度均有显著增长。Hotz钢板组对唇腭裂患者的上颌骨发育有较好的疗效。

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.
