BACKGROUND/OBJECTIVES: The success of the orthopaedic treatment is closely related to the patient's skeletal maturation. This study aimed to evaluate the midpalatal suture (MPS), the zygomaticomaxillary suture (ZMS) maturation, and the closure degree of the spheno-occipital synchondrosis (SOS) in patients of different age groups. The presence of a correlation between these parameters and the palatal dimensions was also verified.
SUBJECTS/METHODS: The study was based on computed tomography images of 314 patients between 7 and 30 years of age with no orthodontic treatment history. The images were retrieved from the archive of the Radiology Department of Bezmialem Vakif University Hospital and divided into six groups according to the patient's age: 7-10, 11-13, 14-16, 17-20, 21-25, and 26-30 years. The maturation scores of ZMS, SOS, and MPS were determined, and palatal thickness and length were recorded. The data were analysed by using Statistical Package for Social Sciences for Windows 22.0.
A positive relationship was found between SOS closure degree and MPS/ZMS maturation (MPS-ZMS: r = 0.816, MPS-SOS: r = 0.736, ZMS-SOS: r = 0.868, P = 0.000). The degrees of ZMS and MPS maturation were significantly increased as the SOS closure degree increased. The MPS maturation score was significantly lower in patients with a short and thick palate (MPS-palatal thickness: r = 0.405, MPS-palatal length: r = 0.387, P = 0.000).
A positive correlation indicated the simultaneous progress in the maturation of the SOS, MPS, and ZMS. Moreover, the ANS-PNS length increase was found to be correlated with the increase of the MPS, ZMS, and SOS maturation scores. In contrast, a negative correlation was observed between the palatal thickness and the maturation stage of these structures.
背景/目的：矫形治疗的成功与患者的骨骼成熟度密切相关。本研究旨在评估不同年龄组患者的正中腭缝（MPS）、颧骨上颌缝（ZMS）成熟度以及蝶枕缝（SOS）的闭合程度，并验证这些参数与腭部尺寸之间是否存在相关性。
受试者/方法：该研究基于 Bezmiâlem Vakif 大学医院放射科档案中 314 名无正畸治疗史的 7 至 30 岁患者的计算机断层扫描图像。将图像根据患者年龄分为 6 组：7-10 岁、11-13 岁、14-16 岁、17-20 岁、21-25 岁和 26-30 岁。确定 ZMS、SOS 和 MPS 的成熟评分，并记录腭部厚度和长度。使用 Windows 22.0 的社会科学统计软件包对数据进行分析。
SOS 闭合程度与 MPS/ZMS 成熟度呈正相关（MPS-ZMS：r = 0.816，MPS-SOS：r = 0.736，ZMS-SOS：r = 0.868，P = 0.000）。随着 SOS 闭合程度的增加，ZMS 和 MPS 成熟度显著增加。MPS 成熟评分在腭部短而厚的患者中明显较低（MPS-腭部厚度：r = 0.405，MPS-腭部长度：r = 0.387，P = 0.000）。
SOS、MPS 和 ZMS 的成熟度呈正相关，提示其同步进展。此外，还发现 ANS-PNS 长度增加与 MPS、ZMS 和 SOS 成熟评分的增加相关。相反，在这些结构的成熟阶段与腭部厚度之间观察到负相关。
