November 27, 2020What is the structure of the species?
The middle part of the face or midface in terms of anatomy includes the ossification of the maxilla and cheekbones and soft tissue and adipose tissue that is located on this area and in terms of appearance of this area (cheeks) above the eyes, below the horizontal line of the lips It leads to the nose from the inside and to the ears on both sides from the outside, and it is one of the most important and effective parts in creating a harmonious and beautiful face. This part of the face, which includes the maxilla, a part of the mandible, and the cheekbones in the upper outer part, is covered by connective tissue and thick fat that makes the skin look fresh and elongated. .
What is Cheek Surgery?
In children and adolescents, who generally have prominent and full cheeks, the face looks beautiful, fresh and cheerful. By entering middle age, the cheeks gradually become weak, wrinkled, and with a decrease in bone volume and connective tissue, and smooth The cheeks become sunken, the middle part of the face is sunken and is accompanied by the fall of the lateral part of the face below the cheekbones. In a group of people, due to the small size of the cheekbones or upper jaw, the maintenance of connective tissue and adipose tissue of the cheeks in this part of the face is very weak, and from an early age, the cheeks of the face appear small and weak in terms of ossification. arrives. In this case, if there is a large nose or large eyes, this defect will be more visible and the patient will simply perform the nose operation without knowing the causes of facial imbalance. Although this operation is able to solve some of the problems of the person’s face, but until the cheek area is corrected and strengthened, the patient will not be satisfied with the result of his nose operation. Therefore, in people who have a small face with poor ossification, as well as a large nose, lips and eyes, one of the methods of balancing the face is proper cheek surgery and cheek surgery.
Suitable people for cheek surgery
Patients who need species and species formation are people who, despite having a suitable species in youth, enter middle age due to bone resorption and connective tissue in this area and reduced skin collagen production and under the influence of environmental factors such as gravity and radiation. The sun gradually removes the connective tissue and fat of the middle part of the face from its anatomical location and moves downwards and inwards, causing the cheeks to flatten and the middle part of the face to fall out. In this group of patients, the outer part of the face is usually sunken under the cheeks and under the eyes, and the crease between the lips and nose becomes deeper. The skin of this area finds deep wrinkles and protrudes asymmetrically and asymmetrically from under the skin in the areas under the eyes and cheeks. As this process progresses, the youthful face of the person gradually gives way to the depressed and tired face, which is one of the signs of aging. Although the above stages will occur gradually in all individuals over a lifetime, the following factors, as effective factors in this regard, can delay or hasten this issue.
Factors that delay cheek drooping:
1- Existence of strong skeleton in the middle part of the face and thick skin and strong connective tissue.
2- Observing skin hygiene from early childhood and adolescence and using methods to prevent bone resorption and reduce skin collagen production.
Avoid obesity and frequent weight loss and wrong diets that lead to rapid weight loss.
4- Protecting facial skin from the sun using effective and useful physical protectors and sunscreens.
5- Regular hydration of dry, brittle and thin skin.
6- Control of general diseases such as diabetes, hormonal diseases, hyperthyroidism and hypothyroidism.
Other effective factors in causing drooping cheeks and middle part of the face are:
1- Genetic and familial factors
2- Wrong diet
3- Insomnia, anxiety, depression, smoking and alcohol consumption
4- Working in a free environment and exposed to the sun and wind
5 – Lack of proper species structure in youth
Who are the species candidates?
Who is cheek surgery or cheek surgery suitable for?
Young people with weak cheekbones who have an unbalanced middle part of the face and want an attractive and balanced face. And the group of middle-aged people who have suffered from bone and tissue connectivity of the cheekbones and middle part due to the loss of life. Although cheekbone surgery or cheek surgery has a great effect on creating an attractive and balanced face in all the mentioned people, but experience has shown that people who have faces with the following characteristics also get good results from this operation.
1- Fully round faces that do not have proper angles between its various components.
2- Square-shaped faces that have a large lower jaw, in which the imbalance between the middle part of the face and the lower jaw is possible only by placing a suitable cheek.
3- Flat and flat faces (in profile) where the middle part of the face is sunken due to the weakness of fat tissue and connectivity.
4- In people who have very small chins and cheeks.
5- People who have suffered a unilateral or bilateral facial fracture due to an accident or accident and have a sunken and asymmetrical cheek and upper jaw.
6- People who have congenital facial defects and have suffered from unilateral or bilateral facial analysis.
Different sorting methods
There are different methods of sorting, which can be different in each person depending on the type of face and the purpose of performing this method.
Fat injection in cheek surgery
For years, facial plastic surgeons have been thinking about injecting fat into the middle of the face and cheeks to highlight this area. In this way: The results obtained are initially satisfactory for the patient. However, due to the absorption of most of the injected fat, the patient’s face gradually returns to its original state in 3 to 6 months, and therefore in this method, the patient must inject fat repeatedly every 6 months to a year.
Gel injection in cheek surgery
Injection of different synthetic gels has long been used by surgeons as an easy solution for patient speciation, but gel injections have always been associated with complications and limitations.
These include the following:
1- Movement of the gel: In the subcutaneous connective tissue, the gel is gradually moved and under the influence of facial muscle movements and environmental factors such as gravity, it moves downwards and moves from the main injection site, which corrects the patient’s lesions. It will take a lot of effort and sometimes it is irreparable.
2- The movement and (migration) of the pieces or (small particles of the gel) and its absorption in the general system of the body will have unwanted effects, so far no gel for injection in the connective tissue has received the necessary approval from the competent health and medical authorities of the world. Has not received and is not recommended in any way.
Cheek bone surgery
One of the most effective ways to create a suitable cheek is to bring the cheekbones forward, which is a stable and very effective method, but because of the risks of cheek surgery around the eyes and because the cheekbones form part of the outer and lower structure of the eye socket. It is not widely accepted by maxillofacial plastic surgeons and is less commonly used today.
Cheek lift (midface)
One of the effective and useful methods to correct the loss of the middle area of the face and cheeks is to perform midface lift in both classical and endoscopic methods.
In this operation, which uses a mannequin lift cut (forehead and eyebrows) with non-absorbable threads, soft tissue and cheek fat are returned to their previous place and fixed in place. Although this method is very effective in correcting the loss of connective tissue in the middle of the face and correcting the line of the nose and lips, but it is not useful for patients whose cheek size is small or the connective tissue and facial fat have been analyzed and due to technical limitations 3D correction of cheek and midface problems is not, and in these cases, it is better to use cheek prosthesis at the same time.
Cheek prosthesis
With the transformation of the faces of mannequins and cinematic models and at the same time their tendency to have an attractive face, the tendency to highlight the components of the face in the middle and lower part of the face has increased so that the term Contour face as a beauty model is most popular today. Among journalistic models and beauty models, which means having a face with multiple angles and failures. On the other hand, with the evolution of medical engineering technique and making anatomical prostheses according to the shape of facial bones and improving their biocomptibility or compatibility in the body and The ease of facial prosthetic surgery, the use of various facial and cheek prostheses has become a popular method in plastic surgery.
Existence of suitable prostheses with different sizes – ease of surgery, no need for general anesthesia, compatibility of these prostheses with the body and their non-excretion by the body and their insensitivity to the patient, are among the advantages of this surgical method. In such a way that today, with the availability of such prostheses, having a fit and balanced face is no longer far from the mind or specific of the wealthy sections of society and movie stars, and everyone can perform a suitable and desired face surgery with light and outpatient surgery. Acquired.
However, it should be noted that the prosthesis is used by world-renowned brands and has international approvals and, if possible, the F.D.A (American Food and Drug Administration). Second, the following properties are evident on the prosthesis guide sheet.
1- Material used in prosthesis
2- Its compatibility with the body and ensuring the health of its use
3- Having an anatomical shape suitable for the cheek and the middle area of the face.
4- The prosthesis should be non-smooth and with Nonsmooth or Texture surfaces so as not to cause bone irritation.
