概括
口腔扩张并不能纠正鼻隔膜偏差;相反,随着时间的推移,偏差会恶化. 这项研究使用3D成像来分析口腔扩张后鼻腔隔膜形状的变化.
科学领域:
- ортодонтика和牙科人类学
- 头骨和面部外科手术
- 医学成像分析 医学成像分析
背景情况:
- 大的横向差异通常用 palatal 扩张来治疗.
- 这些差异与鼻隔膜偏差之间存在潜在的联系.
- 以前对快速 palatal 膨胀对鼻腔隔膜的影响的 2D 放射性研究缺乏确的证据.
研究的目的:
- 通过3D几何形态测量来研究口腔扩张后鼻腔隔膜形状的变化.
- 分析形光束计算机断层扫描 (CBCT) 数据,以详细评估隔膜形态.
- 为了比较经过 palatal expansion 和对照组的患者之间鼻腔隔膜的变化.
主要方法:
- 在两个时间点分析了71名受试者的CBCT扫描 (53个扩展,18个控制).
- 使用MimicsTM软件创建了3D模型,通过CheckpointTM数字化了地标.
- 概括的Procrustes分析,主要组件分析和热映射被用来评估形状变化.
主要成果:
- 对照组在时间点之间的隔膜偏差没有显著变化.
- 在扩张组中观察到隔膜偏差的显著变化.
- 热图显示后顶隔膜发生了最大的变化,而中部,下部显示最小的变化.
结论:
- 口腔扩张不会导致鼻腔隔膜直.
- 鼻隔膜偏差似乎随着年龄的增长而进展,即使在 palatal 扩张治疗后.
- 这项研究强调了上腺发育和鼻腔隔膜形态之间的复杂相互作用.

Nose and Nasal Cavity
10.5K
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

Cranial Bones: Lateral View
4.4K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
