气囊动脉,在鼻提升过程中潜在的出血来源,在老年患者和更宽的鼻中更为常见. 它的骨运河是骨运河.
科学领域:
- 人体解剖学 解剖学 解剖学
- 放射学 放射学是一门学科.
- 在口腔外科手术.
背景情况:
- 膜关动脉,后上膜动脉和外轨道动脉之间的解剖,可以穿过侧面大壁的骨通道.
- 这条动脉在侧面鼻提升手术期间存在风险,包括出血和瘤形成.
- 它的解剖过程可以在软组织内,使其在形光束计算机断层扫描 (CBCT) 上无法检测到.
研究的目的:
- 为了调查侧面大壁中含有大膜门动脉的骨通道的存在和解剖关系.
- 为了确定与患有这种骨通道的可能性更高相关的患者特征.
- 通过使用稳定的解剖结构,如硬 palatus 和鼻宽度,建立预测标记,以确定膜腹动脉的存在.
主要方法:
- 对符合纳入标准的148名患者的CBCT扫描进行了回顾性分析.
- 根据患者的性别,年龄和上鼻类型 (宽,平均,窄) 进行患者的表征.
- 测量骨通道的直径及其与鼻腔底部和硬 palates 的空间关系.
主要成果:
- 在57.0%的患者中,确定了含有膜关动脉的骨通道.
- 年龄较大 (p=0.064) 和鼻较宽与骨通道的更高患病率有关.
- 硬 palates 的水平作为一个可靠的预测器在牙和前牙区域;通道宽度在男性更大 (p=0.015).
- 从鼻腔底部较小的距离和牙的存在 (p=0.067) 之间发现了相关性,牙损失后增加了牙.
结论:
- 了解膜关动脉的解剖学对于最大限度地降低风险至关重要,比如在侧面鼻升降时动脉出血等风险.
- 标准的手术前检查CBCT为预测这种动脉存在提供了有价值的数据.
- 硬口腔和鼻的宽度可以帮助预测膜关动脉的位置,改善手术规划.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...
Imaging Studies for Cardiovascular System III: X-Ray
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
