概括

上鼻角 (UNLA) 与下对齐相关,较高的UNLA在II类,较低的UNLA在III类不良闭合. 鼻腔形态显示性别差异,但骨和鼻子参数不能可靠地预测缺陷类型.

科学领域:

矯正牙科矯正牙科是一種矯正牙科.
头骨面部形态学头骨面部形态学
人类测量学人类测量学.

背景情况:

上鼻角 (UNLA) 对于诊断和规划正牙治疗至关重要.
了解UNLA与骨和鼻子参数的关系对于准确的评估至关重要.

研究的目的:

在印度人群中,将骨参数与鼻腔形态,特别是UNLA相关联.
为了研究鼻腔形态的基于性别的差异.
为了确定骨缺陷的最佳UNLA切线值.

主要方法:

追溯分析了162个治疗前的横向脑膜测量记录.
根据ANB角度将患者分为骨I,II和III类.
根据生长模式 (水平,平均,垂直) 使用SN-GoGn角度进行细分.
统计分析包括相关性,回归,曼-惠特尼U,克鲁斯卡尔-瓦利斯和ROC曲线.

主要成果:

UNLA与上垂位置正相关,与下位置和口腔平面倾斜负相关.
在鼻子长度,深度和下前面面部高度方面发现了显著的性别差异.
最佳的UNLA切线:在II类时≥20°,在I类时≥16-20°,在III类时≤16°.
骨和鼻子参数不是骨模式的可靠预测指标.

结论:

在骨II类缺陷中,UNLA随着下方 palatal 平面倾斜而增加.
骨III类恶性闭塞与一个向上倾斜的鼻尖有关.
UNLA 作为特定骨缺陷类型的指标.

Cranial Bones: Lateral View

Cranial Bones: Lateral View

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...

Assessment of Airway, Skin Color, and Use of Accessory Muscles

A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.
Introduction
The initial evaluation of a patient's respiratory system...
