Abstract

Objectives

This study aimed to assess the relative growth rates (RGRs) of the maxilla and mandible at varying fusion stages of the spheno-occipital synchondrosis (SOS), thereby elucidating the potential of SOS stages in predicting maxillomandibular growth.

Materials and Methods

A total of 320 subjects (171 boys and 149 girls), aged 6 to 18 years, were retrospectively included. Each subject had a minimum of two longitudinal cone-beam computed tomography (CBCT) images, with no more than one interval of SOS fusion stage change between the two scans. Subjects were categorized based on their SOS fusion stages and genders. The RGRs of the maxilla and mandible at various SOS fusion stages were measured and compared using longitudinal CBCT images.

Results

Significant statistical differences were observed in maxillomandibular RGRs across various SOS fusion stages. In girls, the sagittal growth of the maxilla remained stable and active until SOS 3, subsequently exhibited deceleration in SOS 4–5 (compared to SOS 3–4, P < .05) and continued to decrease in SOS 5–6. Whereas in boys, the sagittal growth of the maxilla remained stable until SOS 4, and a deceleration trend emerged starting from SOS 5 to 6 (P < .01 compared to SOS 4–5). Mandibular growth patterns in both genders exhibited a progression of increasing-accelerating-decelerating rates from SOS 2 to 6. The highest RGRs for total mandibular length were observed in SOS 3–4 and SOS 4–5.

Conclusion

Spheno-occipital synchondrosis fusion stages can serve as a valid indicator of maxillomandibular growth maturation.

将脊枕骨突融合阶段作为评估上颌骨生长指标的可行性：混合纵向研究。

研究目的本研究旨在评估上颌骨和下颌骨在脊枕骨突（SOS）不同融合阶段的相对生长率（RGRs），从而阐明SOS阶段在预测上下颌骨生长方面的潜力：回顾性纳入了 320 名年龄在 6 至 18 岁之间的受试者（171 名男孩和 149 名女孩）。每个受试者至少有两次纵向锥束计算机断层扫描（CBCT）图像，两次扫描之间的SOS融合阶段变化间隔不超过一次。受试者根据其 SOS 融合阶段和性别进行分类。使用纵向 CBCT 图像测量并比较不同 SOS 融合阶段的上颌骨和下颌骨的 RGR：结果：在不同的 SOS 融合阶段，上颌骨和下颌骨的 RGR 存在显著的统计学差异。在女孩中，上颌骨的矢状面生长在 SOS 3 之前保持稳定和活跃，随后在 SOS 4-5 阶段出现减速（与 SOS 3-4 阶段相比，P脊枕骨突融合阶段可作为上颌骨生长成熟的有效指标。
