| 摘要目的：研究成人骨性II类不同垂直骨面型上气道与舌骨形态及位置的差异。方法：随机选择60 名成人骨性II 类患者，男女
比例1:1，依据GoGn-SN角分为三组(高角组、均角组及低角组)，在自然头位下拍摄CBCT，运用MIMICS 软件对上呼吸道及舌骨
进行三维建模并测量21 项相关指标，分析不同垂直骨面型之间上气道各段之间及舌骨形态、位置的差异。结果：不同垂直骨面型
之间鄂咽上界平面矢状径长度(PNSL)存在显著性差异(P<0.05)，上气道各段高度(UTH、ETH)及宽度(PNSW、UTW、ETW)之间比较
无统计学差异(P>0.05)。高角组上气道鄂咽下界及舌咽下界矢状径长度(UTL、ETL)与均角和低角组均存在显著差异(P<0.01)，随着
垂直骨面型增大，呈现高角<均角<低角的趋势。高角组上气道鄂咽及舌咽体积明显小于均角和低角，差异有统计学意义(P<
0.05)。舌骨形态及位置在不同垂直骨面型之间无差异(P>0.05)。结论：不同垂直向生长方式对上气道产生影响较大，而对舌骨的生
长发育无影响。 |

| ABSTRACT Objective:To study the differences between different the patterns of hyoid bones and the upper airway form in skeletal
Class II patients. Methods:The sample (30 males and 30 females)of skeletal Class II patients were randomly selected. According to the
GoGn-SN angle, the patients were divided into three groups (high angle group, normal angle, or low angle). Cone-Beam computed tomography
(CBCT) were carried out under natural head postures. The 3D modeling of upper airway form and hyoid bone were generated
by using MIMICS software, and 21 indices were measured. The lengths of airway, dimentions and locations of hyoid bones were compared
among the three groups. Results:The length of the sagittal in the palatopharynx of the high angle group was statistically different
fromthat of the low and the normal angle group(P<0.05). No difference was found for palatopharynx and glossopharyn heights(UTH and
ETH) between the low angle group and that of normal angle group. Also, no significant difference was observed for the width of upper
airway among different vertical skeletal facial(P＞0.05). In the cross-length of upper airway, a significant tendency for reduced upper airway
dimension in the glossopharynx was found in the low angle, normal angle, and high angle subgroups, in that order, with statistically
significant differences (P<0.01). There were different in palatopharynx and glossopharynx volumes among different vertical skeletal patterns
(P<0.05). But no differece was found between the shape and position of hyoids among different vertical skeletal facial (P＞0.05).
Conclusion:Different vertical patterns of skeletal Class II were related to the shape of upper airway, but this effect was not observed for
the hyoid bone. |
