Resumen
Esta revisión presenta el Remodelado de Piel, SMAS y Ligamentos (SSLR), una técnica de relleno basada en la anatomía para el lifting facial dinámico. SSLR utiliza una colocación precisa del relleno para lograr una elevación y animación natural con un mínimo de producto.
Área de la Ciencia:
- Dermatología
- Medicina Estética
- Anatomía Facial
Sus antecedentes:
- Las técnicas contemporáneas de relleno han evolucionado desde la simple volumización hasta el lifting basado en la anatomía funcional.
- Esta revisión sintetiza un marco que integra el remodelado de la piel, el SMAS (Sistema Musculoaponeurótico Superficial) y los ligamentos (SSLR).
- El enfoque SSLR tiene como objetivo la elevación facial dinámica, compatible con las expresiones, utilizando una cantidad mínima de producto de relleno.
Objetivo del estudio:
- Presentar un marco para lograr el lifting facial dinámico a través de un enfoque novedoso para la inyección de relleno.
- Explicar el mecanismo del lifting facial como un fenómeno de redistribución de tensión.
- Proporcionar una estrategia reproducible y guiada por la anatomía para el rejuvenecimiento facial.
Principales métodos:
- Basándose en la anatomía específica de las capas y los patrones de envejecimiento, SSLR implica la colocación precisa de pequeños bolos de relleno de alta cohesividad.
- Las inyecciones se administran estratégicamente en inserciones de ligamentos densos y grasa sub-SMAS.
- Se utilizan microdepósitos dérmicos/subdérmicos para mejorar la envoltura de la piel y atenuar la transmisión de arrugas.
Principales resultados:
- SSLR explica el lifting clínico como un fenómeno de redistribución de tensión, independiente de la acción muscular específica.
- La expansión sub-SMAS y el refuerzo de los ligamentos conducen a mejoras predecibles en el descenso de la mitad de la cara, los pliegues nasolabiales y la definición de la línea de la mandíbula.
- Volúmenes conservadores de relleno logran un rejuvenecimiento significativo, respaldado por observaciones de mecanorreceptores similares a Ruffini que influyen en el tono facial.
Conclusiones:
- La anatomía funcional proporciona una justificación clara de cómo los depósitos de relleno pequeños y específicos del plano producen efectos de lifting sustanciales.
- SSLR ofrece una estrategia reproducible y guiada por la anatomía para restaurar la armonía facial tridimensional.
- Esta técnica es aplicable en diversos sexos y etnias, preservando la animación facial natural.

Lift
547
Lift is a fundamental aerodynamic force that acts perpendicular to the direction of airflow. It plays a central role in achieving and sustaining flight and in stabilizing various vehicles. Lift primarily originates from pressure differences created across surfaces, such as an airfoil. A lower pressure region forms above the wing, while a higher pressure region forms below it, generating an upward force. This differential results from the shape and orientation of the airfoil, enabling the wing...

Additives and Fillers in Concrete
355
Additives and fillers are integral to enhancing the properties of concrete. Pozzolans and blast-furnace slag are additives or admixtures due to their reactions with calcium hydroxide released during cement hydration. Fillers, which are finely ground and similar in fineness to Portland cement, improve concrete attributes such as workability density, and reduce capillary bleeding or cracking. Some fillers possess hydraulic properties or participate in benign reactions within the cement paste.

Exponential Functions with Base e
256
Exponential functions with base e are essential for modeling continuous processes of growth and decay. The constant e, approximately 2.718, naturally arises in systems where change occurs proportionally to the current value. A positive exponent represents continuous growth, while a negative exponent represents continuous decay. These functions are especially useful for describing situations where change happens smoothly over time rather than in discrete steps.One clear example of exponential...

Anatomy of the Heart
120.0K
The human heart is made up of three layers of tissue that are surrounded by the pericardium, a membrane that protects and confines the heart. The outermost layer, closest to the pericardium, is the epicardium. The pericardial cavity separates the pericardium from the epicardium. Beneath the epicardium is the myocardium, the middle layer, and the endocardium, the innermost layer. There are four chambers of the heart: the right atrium, the right ventricle, the left atrium, and the left ventricle.

Anatomy of the Eyeball
9.8K
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle...

Tooth Anatomy

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
