Summary
Aging cranium shows lateral expansion and decreased volume, contributing to facial soft-tissue laxity in older adults. This study investigated cranial changes with age.
Area of Science:
- Gerontology
- Anatomy
- Medical Imaging
Background:
- Cranial aging and its effects on facial soft tissues are not well understood.
- Limited data exists on age-related changes in skull morphology.
Purpose of the Study:
- To investigate age-related changes in the cranium.
- To propose a mechanism for reduced support of facial soft tissues in aging.
Main Methods:
- Computed tomographic (CT) scans of 157 individuals across various age decades.
- Standardized measurements of cranial thickness, diameters, and volumes were performed.
Main Results:
- Cranial volume decreased with age in both males and females.
- Skull exhibited lateral expansion (increased transverse diameter) and decreased sagittal diameter with aging.
- Frontal bone thickness decreased in males but slightly increased in females.
Conclusions:
- Decreased calvarial volume with age contributes to facial soft-tissue laxity.
- Lateral skull expansion may lead to a more 'skeletonized' facial appearance in the elderly.

Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

01:10Line Loss
547
The different configurations of source-load connections include wye (star) and delta connections. The relationship between line and phase voltages and currents varies depending on the configuration. When the source is supplying power, it is transmitted through the wires to the load, and during this transmission, some power is absorbed by the wires, leading to line loss.
Line loss impacts power delivery efficiency in a balanced three-phase circuit. The symmetry in such a circuit simplifies the...

01:14Muscles for Facial Expressions
5.0K
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...
