Abstract：
This is a prospective study examining palatal casts from patients with unilateral cleft lip and palate (UCLP) in the first month of life, immediately before cheiloplasty, and immediately before palatoplasty. None of the patients receives presurgical orthopedics (nasoalveolar molding).
In this prospective study, upper arch plaster models were taken 3 times during the treatment: in the first month of life (T1), before the cheiloplasty (T2), and before the palatoplasty (T3). Anatomic landmarks were defined and linear anthropometric measurements were obtained afterward. Dimensional analysis was performed using 3D software. Two-way analysis of variance followed by Tukey test was performed for statistical analysis.
Tertiary, institutional.
Twelve patients with UCLP of either sex with less than 1 month of life and without any other syndrome.
No intervention was performed.
Reduction of the cleft without using orthopedics apparatus.
There was a statistically significant reduction in the cleft gap comparing T1 to T3. There was also a significant reduction in the intercanine width comparing T2 and T3, and T1 and T3. There was significant increase in the posterior arch width comparing T2 and T3, and T1 and T3. The palatal plate\'s width increased in all times analyzed.
The palatal cleft narrows spontaneously as well in both midpoint and posterior point during the first 6 months of patient\'s treatment. This event was enhanced by cheiloplasty. This surgery might have a greater influence on the anterior arch width than in the posterior arch region.

摘要：
这是一项前瞻性研究，检查单侧唇腭裂（UCLP）患者在出生后第一个月的腭管型，在唇缘成形术之前，就在腭成形术前。没有患者接受术前骨科（鼻肺泡成型）。
在这项前瞻性研究中，上弓石膏模型在治疗期间采取3次：在生命的第一个月（T1），唇膏整修前（T2），在腭成形术前（T3）。定义了解剖标志，然后获得了线性人体测量。使用3D软件进行尺寸分析。进行双向方差分析，然后进行Tukey检验进行统计分析。
第三纪，机构。
12例UCLP患者，无论性别，生命少于1个月，无任何其他综合征。
未进行干预。
在不使用骨科器械的情况下减少裂隙。
与T1和T3相比,裂隙有统计学上显著的减少。与T2和T3以及T1和T3相比，犬间宽度也显着降低。与T2和T3以及T1和T3相比，后弓宽度显着增加。在分析的所有时间中，the板的宽度都增加了。
在患者治疗的前6个月中，腭裂在中点和后点自发变窄。该事件通过唇缘成形术得到加强。与后弓区域相比，该手术对前弓宽度的影响可能更大。
