Facial anatomy for cosmetologists: how to bypass danger zones (video)

In order to safely carry out any injection techniques for facial rejuvenation, it is necessary to know exactly the danger zones where the branches of the nerves and large vessels pass. Today we will tell you in detail how the mimic muscles of the face are located, dwell on the features of the blood supply and innervation of the zones in which it is necessary to carry out aesthetic correction.

With age, the appearance and outlines of the face change. The reason for such changes is the weakening of the muscles of the face and neck, which decrease in volume and deform, while their tone decreases. This entails the need for the introduction of fillers and botulinum toxins.

For a safer work of a cosmetologist, the performance of any cosmetic procedures or manipulations of the facial area inevitably requires knowledge of the anatomy and topography of the formations of this zone. Estet-portal.com will not only describe, but also demonstrate the video lesson "anatomy of facial aging for cosmetologists".

Anatomical structures: nerves, vessels, vessels of the face

There are several important aspects of facial anatomy for cosmetologists that need to be assessed by the doctor before starting work:

1. Using botulinum toxin in work, it is necessary to clearly understand and represent the work of facial muscles, the place of origin and attachment of the muscle, its size, strength, the number of muscle bundles and fibers, interlacing and interaction of muscles with each other.

2. Working with needles requires precise knowledge of the location of the vessels, possible places of their damage or puncture, pressure points in emergency cases.

3. Knowledge of the innervation of the face, the difference between sensory and motor branches of the nerves sometimes becomes a decisive factor in determining the cause of deformation or asymmetry on the face.

Nerves of the face anatomy

Motor innervation of the face (innervation of the mimic muscles) is provided by branches of the facial nerve (n.facialis):

• rr.colii cervical branches – platysma innervation;
• rr.marginalis mandibulae extreme branches of the lower jaw – innervation of the muscles of the chin and lower lip;
• rr.buccalis buccal branches – innervate the muscle of the same name and the muscle that lowers the corner of the mouth;
• rr.zygomatici zygomatic branches – innervates the large and small zygomatic muscles, the muscle that lifts the upper lip and wings of the nose, partially the circular muscle of the eye and the cheek muscle;
• rr.temporalis temporal branches – innervates the orbicular muscle of the eye, the muscle that wrinkles the eyebrow, the frontalis muscle and the anterior part of the ear.
• Sensitive innervation of the face and neck is provided by the branches of the trigeminal nerve (n. trigeminus), supratrochlear (n. supratrochlearis), supraorbital (suprorbitalis), infraorbital (n.infraorbitalis) and mental (n.mentalis) nerves.

Blood supply of the face anatomy

The blood supply to the face is carried out to a greater extent by the branches of the external carotid artery (a.carotis externa): a.facialis, a.temporalis superfacialis, a.maxillaris.

In the region of the orbit, there is an anastomosis between the external and internal carotid arteries with the help of a.ophtalmica. The vascular network on the face is very developed, which, on the one hand, ensures perfect nutrition of all areas, and on the other hand, it means that an injury to one of the vessels can lead to severe bleeding.

Mimic muscles of the face anatomy

Name "mimic muscles" – functional. In the course of evolution, they were transformed from specially adapted structures for capturing food, acute smell and hearing into facial muscles, the contraction of which moves the skin of the face in accordance with the psycho-emotional state of a person, and is also responsible for the articulation of speech;

Mimic muscles are mainly concentrated around the natural openings on the face, expanding or closing them.

The most complex structure and the greatest number are the muscles surrounding the oral cavity.

In accordance with their development, the facial muscles have a close relationship with the skin of the face, into which they are woven with one or two ends. For us, this is important because in the process of skin aging, loss of elasticity and firmness, they cannot adequately contract, the muscular frame weakens. This underlies the ptosis of the skin and the appearance of mimic wrinkles on the face;

Most often, botulinum toxin injections occur on the frontal abdomen of the occipital-frontal muscle, the circular muscle of the eye, the circular muscle of the mouth, the muscles that lower the corner of the mouth and lower lip, the chin muscle, since their active contraction causes the reflection of our psycho-emotional state in facial expressions.
