This study aimed to correlate the cervical vertebrae maturation (CVM) stages with the bone fusion stages of the midpalatal suture (MPS).
The sample consisted of 351 cone-beam computed tomographies (CBCTs) of patients divided into two groups: 10-15 years old and 16-20 years old. Both CVM and MPS stages were correlated using Spearman's correlation analysis. To assess the diagnostic performance of the CVM stages in identifying the bone fusion stages of the MPS, the likelihood ratio (LHR) test was applied.
In the whole sample, a low positive correlation was found between CVM and MPS bone fusion level (P<0.001; Rho=0.395). In the younger age group, the correlation was moderate in the male (P<0.001; Rho=0.616) and low in the female (P<0.001; Rho=0.394) patients. In the 16-20 years age group, there was no correlation between CVM and MPS fusion. A moderate increase in the probability of determining CS1 for stage A (38%) and CS2 for stage B (42.2%) of MPS ossification was found among the 10-15 year old female patients.
A low and moderate positive correlation was found between CVM and MPS level of bone fusion in female and male patients respectively, but the diagnostic performance of the CVM stages in the identification of MPS bone fusion stages did not have a high correlation. Therefore, the CVM stages indicated no conclusive probability of determining the MPS bone fusion stage.
本研究旨在探讨颈椎成熟度（CVM）分期与正中腭缝（MPS）骨融合分期的相关性。
本研究样本包括 351 例经锥形束 CT（CBCT）检查的患者，分为 10-15 岁和 16-20 岁两组。采用 Spearman 相关分析对 CVM 和 MPS 分期进行相关性分析。应用似然比（LHR）检验评估 CVM 分期对 MPS 骨融合分期的诊断性能。
在整个样本中，CVM 与 MPS 骨融合水平之间呈低度正相关（P<0.001；Rho=0.395）。在年龄较小的组中，男性患者的相关性较强（P<0.001；Rho=0.616），女性患者的相关性较弱（P<0.001；Rho=0.394）。在 16-20 岁年龄组中，CVM 与 MPS 融合之间无相关性。在 10-15 岁女性患者中，CVM 分期为 A 期的 CS1（38%）和 B 期的 CS2（42.2%）的概率适度增加。
在男性和女性患者中，CVM 与 MPS 骨融合水平之间存在低度和中度正相关，但 CVM 分期在识别 MPS 骨融合分期方面的诊断性能没有高度相关性。因此，CVM 分期并不能确定 MPS 骨融合阶段。
