Cosmetic Surgery and Liposuction: Principles, Applications, and Aesthetic Standards Analysis

What kind of discipline is cosmetic surgery?

Cosmetic surgery is a newly emerging discipline that has separated from plastic surgery in recent years and developed rapidly, integrating clinical medicine, human aesthetics, and psychology. In terms of the patients, cosmetic surgery involves "aesthetic shaping and processing" of basically normal individuals to improve their appearance and body shape to near-ideal levels, making them feel younger and more beautiful, enhancing their vitality, or restoring their artistic youth. This also plays an important and positive role in the development of society as a whole.

Human spiritual needs are similar to material needs. As material living standards reach a certain level of satisfaction, these spiritual needs become increasingly apparent. The desire for beauty is universal; the hope to maintain youth and extend one's participation in social activities is a universal desire. Cosmetic surgery is precisely such a discipline. With the progress of the times, it applies advanced medical technology to the greatest extent possible to meet the spiritual needs of those with a strong desire for beauty, enabling them to experience a qualitative leap in their lives.

Cosmetic surgery, also known as "psychosomatic surgery" abroad, uses surgical methods to treat psychological issues that cannot be resolved by medication or psychotherapy alone. It aims to eliminate feelings of inferiority, build self-confidence, and help some individuals regain their will to live.

Cosmetic surgery is a highly selective procedure. Success is the only acceptable outcome; failure is not an option. Failure not only means failing to achieve the desired cosmetic result but also carries the risk of disfigurement, causing immense psychological trauma that can be difficult to bear and potentially lead to serious consequences. While highly selective, cosmetic surgery also has a dual selectivity. Patients who strongly request a particular cosmetic procedure, but whose examination determines are unnecessary or unsuitable for the procedure, should never be forced to undergo surgery. Doing so can lead to unexpected consequences and disputes post-surgery.

Are liposuction and fat grafting considered cosmetic surgery?

Many people believe that cosmetic surgery only includes procedures like double eyelid surgery, facelifts, rhinoplasty, and breast augmentation. However, these are only a part of cosmetic surgery. Over the past 20 years, liposuction has become increasingly sophisticated and has developed rapidly. In particular, the successful clinical application of fat grafting in recent years has fundamentally changed the nature of cosmetic surgery, injecting new vitality into it.

The main function of liposuction and fat grafting is to make a person's appearance and figure slimmer or fuller, maintaining a balanced and harmonious beautiful figure. Liposuction and fat grafting address many issues related to appearance and body shape. From the current medical perspective, no other surgery can achieve or replace the results of these two procedures. Therefore, cosmetic surgery would be incomplete without liposuction and fat grafting.

What are the aesthetic standards for the human head and neck?

According to the theory of human artistic anatomy, from a frontal view, the human face is divided into "three sections and five eyes" (Figure 1): One "section" is the distance from the midpoint between the eyebrows to the bottom of the nostrils; the distances from the midpoint between the eyebrows to the hairline and from the bottom of the nostrils to the tip of the beard should be equal to form the "three sections." "Five eyes" refers to the width of the face on the horizontal line of the eyes being exactly five eye widths; that is, there is one eye width between the eyes, and one eye width from the outer corner of each eye to the outermost edge of the cheek. From a side view, the front edge of the lower lip is located inside the line connecting the tip of the nose to the tip of the chin, and the front edge of the upper lip is slightly recessed within this line.

The lengths of these "sections" and "eyes" establish the generally accepted aesthetic standards; being too long or too short is considered unattractive. Cosmetic surgery is designed based on these standards for determining beauty. For example, if the distance from the lower nasal wing to the chin is too short, the anterior edge of the lower lip will inevitably protrude beyond the line connecting the tip of the nose and the tip of the chin. In this case, the height and length of the chin should be increased; chin augmentation can correct this deficiency.

While these aesthetic standards exist, they are not absolute values. Each person's face possesses unique features, and these features contain beauty that others lack. From an anatomical perspective, the skeletal structure of the head and neck is similar for people of the same age, making accurate differentiation difficult. However, when considering the face, which is covered by muscles, fat, and skin, it is often easy to remember someone's features through various connections. Among these features are aspects that are pleasing or admirable.

Cosmetic surgeons should not only master the specific data of these aesthetic standards but also be adept at identifying the distinctive features of their patients. Through cosmetic surgery, they can refine these features, allowing the beautiful aspects to be more perfectly revealed.
