The modern data about the anatomy of a dangerous triangle of the face

The anatomical structures of the facial skin are susceptible to various damage and can be affected when the integrity of the skin is violated, both at home and during invasive procedures or surgical interventions. In such cases, there is a danger of rapid spread of infection, mainly through the blood flow through the valve-less vessels of the face and head, which can lead to damage to the brain, organ of vision and other structures. The so-called danger zones of the face are especially vulnerable - areas of the skin, damage to which is more likely to lead to serious consequences. To prevent the development of complications, a deep understanding of the anatomical structure of these areas of the face is necessary. The purpose of the review is to summarize modern notions about the most dangerous traumatic injuries, various surgical and cosmetic interventions of the anatomical areas in the face, their possible infection, consequences and complications. Traumatization of blood vessels and nerves in dangerous areas of the face, as well as infection of wounds in this area can cause death. The skin of dangerous anatomical areas of the face (the surface of the nasal area, lip area, nasolabial triangle and other areas) is thin and closely connected to the underlying muscles. These areas contain a large number of blood vessels that anastomose with each other, as well as lymphatic vessels and nerve plexuses. An analysis of the frequency of diseases and injuries in these areas shows that currently they are caused by other reasons than what was observed in previous decades, and are more associated with cosmetic procedures of uncontrolled injections of botulinum toxin type A and (or) hyaluronic acid preparations. These methods of rejuvenating the appearance and correcting facial structures are becoming increasingly popular and more dangerous for the anatomically determined reasons mentioned above. All of the above is relevant in the study of facial anatomy by both students and specialists.
