概括
男性的横向面部生长明显大于女性,在12.6岁左右出现明显的差异. 这项研究强调了面部发育中的基于性别的变化,这对于理解生长模式至关重要.
科学领域:
- 头骨面部的发展
- 人类测量学 人类测量学.
- 增长和发展 增长和发展
背景情况:
- 了解典型的横向面部生长模式对于诊断和治疗面异常至关重要.
- 之前的研究已经表明了面部形态的性别差异,但对横向生长模式的详细纵向数据是有限的.
研究的目的:
- 纵向分析从10岁到18岁的个体中横向面部生长的模式.
- 识别横向面部生长的时间和程度的性别特异性差异.
主要方法:
- 一项纵向队列研究,涉及101名10-18岁的个人 (56名男性,45名女性).
- 使用立体摄影仪获得每6个月一次的三维面部表面成像.
- 测量横向面部特征的线性距离,包括嘴唇宽度,鼻子宽度,口腔间距离和外腔口腔距离.
主要成果:
- 观察到唇和鼻子宽度的最低基线性别差异.
- 男人表现出更大的横向增长:鼻子宽度增加了6.0毫米 (男性) 与3.9毫米 (女性),嘴唇宽度增加了5.1毫米 (男性) 与2.1毫米 (女性).
- 两性之间鼻腔和唇部生长模式的差异发生在12.6年左右;男性表现出始终更大的口腔间和外口腔间距离,随着时间的推移而增加.
结论:
- 在女性中,横向面部生长在14岁左右停止,而在男性中持续更长时间.
- 男性的更大增长和更长的持续时间导致青春期后鼻子和嘴唇的尺寸更大.
- 考虑到正常的背景生长,包括性别特异性模式,可以增强对腔扩张等干预措施的分析.

01:14Muscles for Facial Expressions
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...
01:21Deformations in a Transverse Cross Section
When a material is subjected to uniaxial stress, it elongates or contracts in the direction of the applied force, and also undergoes changes in the perpendicular directions. This behavior is crucial for understanding how materials behave under stress and is governed by mechanical properties such as Poisson's ratio v, which measures the ratio of transverse strain to axial strain.
As the material stretches, it expands or contracts in orthogonal directions to the load. This phenomenon varies...
