This study aimed to evaluate the zygomaticotemporal suture (ZTS) maturation, analyze the age distribution patterns of ZTS maturation stages, and investigate the relationship between ZTS and cervical vertebral maturation (CVM).
A total of 261 patients who underwent cone-beam computed tomography (112 males, mean age, 13.1 ± 3.3 years; 149 females, mean age, 13.7 ± 3.1 years) were examined to evaluate the ZTS stages. The ZTS stages were defined based on a modified method from previous studies on zygomaticomaxillary sutures. Differences between groups and correlations between indicators were analyzed using the Spearman correlation test, intraclass coefficient of correlation (ICC), one-way analysis of variance and rank sum test. Statistical significance was set at < 0.05. The diagnostic value of CVM stages in identifying ZTS maturation stages was evaluated using positive likelihood ratios (LRs).
A positive relationship was found between the ZTS and CVM stage (r = 0.747, ICC = 0.621, < 0.01) and between the ZTS stage and chronological age (r = 0.727, ICC = 0.330, < 0.01). Positive LRs > 10 were found for several cervical stages (CSs), including CS1 and CS2 for the diagnosis of stage B, CS1 to CS3 for the diagnosis of stages B and C, and CS6 for the diagnosis of stages D and E.
The ZTS maturation stage may be more relevant to the CVM stage than to the chronological age. The CVM stages can be good indicators for clinical decisions regarding maxillary protraction, except for CS4 and CS5.
本研究旨在评估颧颞缝（ZTS）的成熟度，分析ZTS成熟阶段的年龄分布模式，并探讨ZTS与颈椎成熟度（CVM）之间的关系。
共检查了261例接受锥形束计算机断层扫描的患者（112例男性，平均年龄13.1±3.3岁；149例女性，平均年龄13.7±3.1岁），以评估ZTS阶段。ZTS阶段是根据先前关于颧上颌缝研究的改良方法定义的。使用Spearman相关检验、组内相关系数（ICC）、单因素方差分析和秩和检验分析组间差异和指标之间的相关性。统计学显著性设定为<0.05。使用阳性似然比（LRs）评估CVM阶段在识别ZTS成熟阶段中的诊断价值。
发现ZTS与CVM阶段之间存在正相关（r = 0.747，ICC = 0.621，<0.01），ZTS阶段与实际年龄之间也存在正相关（r = 0.727，ICC = 0.330，<0.01）。在几个颈椎阶段（CSs）中发现阳性LRs>10，包括用于诊断B期的CS1和CS2、用于诊断B期和C期的CS1至CS3，以及用于诊断D期和E期的CS6。
ZTS成熟阶段可能与CVM阶段的相关性比与实际年龄的相关性更大。除CS4和CS5外，CVM阶段可为上颌前牵引的临床决策提供良好指标。
