Abstract

Objective: This study aimed to evaluate the differences in cephalometric characteristics and skeletal maturation in girls with central precocious puberty (CPP) via lateral and hand-wrist radiographs. We also aimed to identify the indicators that are most effective for determining skeletal maturity in these patients.

Methods: The study included 70 Korean girls (mean age, 8.5 ± 0.5 years) diagnosed with CPP at the Department of Pediatrics, and 48 normal healthy age-matched girls who visited the Department of Orthodontics and had no history of hormone treatment or growth problems. Skeletal maturation was evaluated using lateral cephalometric and hand-wrist radiographs using cervical vertebrae maturation indicators (CVMI) and skeletal maturity indicators (SMI).

Results: The mean mandibular plane angle was smaller in the CPP group than in the control group (35.8° ± 4.9° vs. 39.0° ± 6.5°), resulting in greater posterior facial height (p = 0.003). SMI was significantly greater in the CPP group (3.5 ± 1.4 vs. 2.0 ± 1.0) than in the control group (p = 0.001) and was significantly associated with CPP (r = 0.492; p = 0.001), whereas CVMI was not.

Conclusions: In comparison with the control group, the CPP group exhibited a smaller mandibular plane angle, greater posterior facial height, and greater skeletal maturation. SMI may be more suitable than CVMI for determining skeletal maturation in CPP. Hand-wrist radiography is recommended in addition to lateral cephalogram for predicting growth in girls with CPP.

中枢性性早熟女孩颈椎和腕关节的头颅测量特征和骨骼成熟的评价。

目的:本研究旨在通过侧位片和腕位片评估中枢性性性早熟(CPP)女孩的头颅特征和骨骼成熟度的差异。我们还旨在确定最有效的指标，以确定这些患者的骨骼成熟度。方法:研究对象为70名在儿科诊断为CPP的韩国女孩(平均年龄8.5±0.5岁)，以及48名在正畸科就诊、无激素治疗史和生长问题的正常健康年龄匹配的女孩。采用颈椎成熟度指标(CVMI)和骨骼成熟度指标(SMI)，通过侧位头颅x线片和腕位x线片评估骨骼成熟度。结果:CPP组平均下颌平面角小于对照组(35.8°±4.9°比39.0°±6.5°)，导致后面部高度增大(p = 0.003)。CPP组SMI显著高于对照组(3.5±1.4比2.0±1.0)(p = 0.001)，且与CPP显著相关(r = 0.492;p = 0.001)，而CVMI则没有。结论:与对照组相比，CPP组下颌平面角较小，面部后高度较大，骨骼成熟程度较高。SMI可能比CVMI更适合于确定CPP患者的骨骼成熟度。在预测CPP女孩的生长情况时，除了侧位脑电图外，还建议进行手腕x线摄影。

期刊介绍： The Korean Journal of Orthodontics (KJO) is an international, open access, peer reviewed journal published in January, March, May, July, September, and November each year. It was first launched in 1970 and, as the official scientific publication of Korean Association of Orthodontists, KJO aims to publish high quality clinical and scientific original research papers in all areas related to orthodontics and dentofacial orthopedics. Specifically, its interest focuses on evidence-based investigations of contemporary diagnostic procedures and treatment techniques, expanding to significant clinical reports of diverse treatment approaches. The scope of KJO covers all areas of orthodontics and dentofacial orthopedics including successful diagnostic procedures and treatment planning, growth and development of the face and its clinical implications, appliance designs, biomechanics, TMJ disorders and adult treatment. Specifically, its latest interest focuses on skeletal anchorage devices, orthodontic appliance and biomaterials, 3 dimensional imaging techniques utilized for dentofacial diagnosis and treatment planning, and orthognathic surgery to correct skeletal disharmony in association of orthodontic treatment.
