Abstract

BACKGROUND

This study aimed to three-dimensionally compare the maxillary growth among the spheno-occipital synchondrosis (SOS) maturation stages in both genders.

METHODS

This is a cross-sectional study of a retrospective type in which cone-beam computed tomography (CBCT) images of 500 patients aged 6 to 25 years (226 males and 274 females) were analyzed. The SOS was evaluated using the four-stage scoring system; completely open, partially fused, semi-fused, or completely fused. The SOS scoring and three-dimensional cephalometric measurements were analyzed by Invivo 6.0.3 software. Descriptive and analytical statistics were performed and a P-value < 0.05 was considered statistically significant.

RESULTS

There was a statistically significant difference in maxillary measurements among SOS maturation stages in both genders (P < 0.05). The mean differences in the maxillary growth among the SOS maturation stages between SOS stages 2 and 3 were higher than those between stages 1and 2 and stages 3 and 4 for maxillary length and height in both genders. However, the mean difference in the maxillary width was higher between SOS stages 1 and 2 than those stages 2 and 3 and stages 3 and 4. On other hand, there may be lesser maxillary growth between SOS stages 3 and 4 for maxillary width, length (in males), and height. The growth curves showed high active growth of the maxilla as the SOS was still fusing (especially stage 2 and 3) than those of the fused (stage 4). Moreover, the acceleration of growth occurred earlier in females than males regarding chronological age but not for SOS maturation stages.

CONCLUSIONS

The SOS maturation stages are valid and reliable maxillary skeletal maturation indicators for three-dimensional maxillary growth in both genders.

摘要

背景

本研究旨在三维比较男女两性蝶枕结合（SOS）成熟阶段的上颌生长情况。

方法

这是一项回顾性的交叉研究，分析了 500 名 6 至 25 岁患者（226 名男性和 274 名女性）的锥形束 CT（CBCT）图像。使用四阶段评分系统评估 SOS；完全开放、部分融合、半融合或完全融合。SOS 评分和三维头影测量分析使用 Invivo 6.0.3 软件进行。进行描述性和分析性统计分析，P 值<0.05 被认为具有统计学意义。

结果

男女两性 SOS 成熟阶段之间的上颌测量值存在统计学差异（P<0.05）。在男女两性中，SOS 成熟阶段 2 到 3 之间的上颌生长差异的平均值大于阶段 1 到 2 之间和阶段 3 到 4 之间的上颌长度和高度。然而，上颌宽度的平均值差异在 SOS 阶段 1 到 2 之间大于阶段 2 到 3 之间和阶段 3 到 4 之间。另一方面，SOS 阶段 3 到 4 之间的上颌宽度、长度（男性）和高度的上颌生长可能较小。生长曲线显示，随着 SOS 仍在融合（尤其是阶段 2 和 3），上颌的生长活跃程度高于融合（阶段 4）。此外，就年龄而言，女性的生长加速比男性更早，但与 SOS 成熟阶段无关。
