The evaluation of midpalatal suture maturation is essential to undertake the most predictable maxillary expansion approach. Several factors, such as age, gender, and facial growth patterns, seem to be involved in midpalatal suture staging and, consequently, in its opening; however, the link between these variables and the stages of midpalatal suture development remains poorly understood. Our study aimed to analyse the midpalatal suture maturation in relation to age, sex, and skeletal growth patterns by CBCT.
We enrolled 263 patients (119 males and 144 females) aged from 8 to 20 years. The midpalatal suture maturation was defined according to Angelieri et al.'s classification using a low-dose CBCT. The chi-square test and linear regression were applied to investigate the suture stages by age, sex, and vertical and sagittal growth patterns.
Stage A was present in 8- and 9-year-olds with a larger prevalence in boys, while the prevalence of stage E increased progressively with age. Stage D was the most prevalent in our sample. The statistical analysis described that stage A was more likely in the youngest subjects, and stage E in the oldest participants. The males tended to have lower maturation stages. Moreover, the hypodivergent and normodivergent subjects tended to have higher maturation stages, while Class III was more likely in subjects in stages D or E.
A total of 127 patients were in stages A, B, and C, showing an unfused suture. In young individuals, the opening of the midpalatal suture leads to a proper facial growth development by correcting the transverse superior hypoplasia. The midpalatal sutural maturation classification was related to age, sex, and divergence.
评估腭中缝成熟度对于采用最可预测的上颌扩弓方法至关重要。年龄、性别和面部生长模式等多种因素似乎与腭中缝分期有关，进而与腭中缝的打开有关；然而，这些变量与腭中缝发育阶段之间的联系仍知之甚少。我们的研究旨在通过锥形束计算机断层扫描（CBCT）分析腭中缝成熟度与年龄、性别和骨骼生长模式的关系。
我们纳入了263名年龄在8至20岁之间的患者（119名男性和144名女性）。使用低剂量CBCT根据安杰利耶里等人的分类来定义腭中缝成熟度。应用卡方检验和线性回归按年龄、性别以及垂直和矢状生长模式来研究缝的阶段。
A期出现在8岁和9岁儿童中，男孩中的患病率更高，而E期的患病率随年龄逐渐增加。D期在我们的样本中最为普遍。统计分析表明，最年轻的受试者更可能处于A期，而最年长的参与者更可能处于E期。男性的成熟阶段往往较低。此外，低角型和均角型受试者往往具有较高的成熟阶段，而Ⅲ类在处于D期或E期的受试者中更常见。
共有127名患者处于A、B和C期，显示缝未融合。在年轻个体中，腭中缝的打开通过纠正横向的上颌发育不全导致面部生长发育正常。腭中缝成熟度分类与年龄、性别和角度有关。
