Abstract

Purpose

This study aims to investigate the anatomical features relating to nasofrontal and septum osteotomy during Le Fort Ⅲ osteotomy among patients with syndromic craniosynostosis, and to compare them with normal controls using computed tomographic cephalometry.

Materials and methods

A total of 63 subjects were included (syndromic craniosynostosis, n = 21; controls, n = 42). The craniosynostosis subjects were subdivided into group A (craniosynostosis patients without history of previous surgery, n = 8) and group B (craniosynostosis patients with history of previous surgery, n = 13). Cephalometric measurements based on computed tomographic images were analyzed.

Results

The angle between the refencing plane (HP) of the anterior cranial base and the most inferior point of the sphenoid sinus via Nasion (∠HP-N-ISS) was 23.85 ± 3.10°, 21.15 ± 4.64° and 28.32 ± 2.92° for group A, group B and the control group, respectively. The angle between HP and the posterior nasal spine (PNS) via nasion (∠HP- N- PNS) was 42.63 ± 2.02°, 38.50 ± 4.84° and 47.68 ± 2.62° for group A, group B and the control group, respectively.

Conclusion

This study characterized the surgically relevant anatomical features in nasofrontal osteotomy during Le Fort Ⅲ osteotomy. The safe range for osteotomy angle is significantly different between normal and syndromic craniosynostosis subjects. Awareness of this difference may prevent further complications.

综合颅畸形患者颅底前部勒堡第Ⅲ截骨术相关解剖特征的头颅测量学研究。

目的：本研究旨在调查综合征颅颧突出症患者在 Le Fort Ⅲ 截骨术中鼻额骨和鼻中隔截骨的相关解剖特征，并使用计算机断层扫描头颅测量法与正常对照组进行比较：共纳入 63 名受试者（综合征颅骨发育不良，21 人；对照组，42 人）。颅骨发育不良受试者被细分为 A 组（既往无手术史的颅骨发育不良患者，n = 8）和 B 组（既往有手术史的颅骨发育不良患者，n = 13）。分析了基于计算机断层扫描图像的头颅测量结果：结果：A 组、B 组和对照组的前颅底反折面（HP）与经 Nasion 的蝶窦最下点之间的角度（∠HP-N-ISS）分别为 23.85 ± 3.10°、21.15 ± 4.64°和 28.32 ± 2.92°。A 组、B 组和对照组的 HP 与经鼻孔的后鼻骨脊柱（PNS）之间的角度（∠HP- N- PNS）分别为 42.63 ± 2.02°、38.50 ± 4.84°和 47.68 ± 2.62°：本研究描述了 Le Fort Ⅲ截骨术中鼻额部截骨的相关解剖特征。截骨角度的安全范围在正常人和综合征颅脑发育不良患者之间存在显著差异。认识到这一差异可预防进一步的并发症。
