Fats are very special components of the human body and are mainly distributed at the body surface (skin) and inside the body (internal organs). Subcutaneous fats account for approximately30% of total fats and anatomically belong to a part of the skin. Therefore, as long as there is skin coverage, there are adipocytes whose main function is to provide protection for skeletal and muscular tissues, regulate body temperature, prop up the skin, and sustain skin elasticity. Excess subcutaneous fat accumulation is prone to cause regional obesity, cellulite, or even skin drooping, thus resulting in a change of stature or appearance. Such problems can be addressed by liposuction, tummy tuck, or other plastic surgeries. Visceral fats comprise over 70% of total fats and are distributed around cavities and organs to protect and cushion vital organs and store energy. Exceeding deposits manifest as systemic obesity or weight gain and have to be resolved by radical weight management or massive exercises to lose body weight.
All such facts clearly indicate that liposuction or lipodissolve therapy is aimed at the selective reduction of subcutaneous fats at targeted body parts to allow patients achieve a rapid and distinct result within the shortest time; this is a part of body contouring rather than systemic weight loss. Moreover, adipocytes accumulate at specific sites due to the prolonged restoration of nutrients and energy at sites such as the arms, abdomen, back waists, or thighs and are difficult to be controlled by exercises or diet control. Therefore, liposuction or lipodissolve injection is the only way to allow patients to reduce the fats in sites they hope to remove them from. Nevertheless, despite fat accumulation being disturbing, excessive fat removal creates other problems. Dr. Chuang has frequently noticed that numerous women are preoccupied with mild obesity but ignore the fact that without fat cushioning and padding, the stature curvature would become unsmooth and poorly proportionate and that drawbacks in skeletal proportion or muscular texture are exposed due to excessive skinniness. Moreover, without fat support, the skin suffers from accelerated aging or looseness. Thus, evaluating the necessity of liposuction not only focuses on fat volumes at a single site but takes into account the overall stature proportion, body weight, skeleton, and age to allow patients to enjoy balanced esthetics that accommodate health and beauty.
Along with the advance in liposuction machines, the concept and method of modern liposuction have experienced tremendous changes. Traditional liposuctions frequently differentiate fats based on their depth. Superficial fats are distributed all over the body, particularly the cheeks, back, buttocks, or calf. They help support the skin and regulate body temperature, as well as store emergency energy necessary when people are hungry or subjected to physical hazards, but due to their close connection with the skin and hard texture, superficial fats are usually difficult to remove by traditional (mechanical) liposuctions, which otherwise easily cause skin depression or unevenness. Deep fats are widely distributed at the arms, abdomen, waist, or thigh, and despite being easy to accumulate due to excess energy intake or obesity, they can be removed by liposuction within a short time, with the results more distinct than those obtained with superficial fats. However, limited by the difference between superficial and deep fats, mechanical liposuction is certainly unable to achieve optimal results. Dr. Chuang adopts the latest composite liposuction, which breaks the barrier of traditional liposuction in the differentiation of superficial and deep fats. Composite liposuction first utilizes Ultra-Z ultrasonic liposculpture (also called Z-wave golden liposculpting) for the simultaneous ultrasonic vibration, melting, and emulsion of superficial and deep fats and breaks the adipose septa and fibers between various layers and then applies the high-speed vacuum liposuction machine (Swiss Medela Dominant 50) to remove dissolved fats outside the human body. This alternative dissolution and suction of fats achieves the comprehensive results of an effective fat volume reduction (deep fats) and curvature contouring (superficial fats).
Apart from the application of new-generation ultrasonic liposuction to remove excess fats, progress has been made in modern medical studies in adipose reuse, and fat grafting has become a hot subject. Traditional fat centrifuge extraction cannot preserve the integrity of adipocytes and frequently damages adipose cells, thus compromising the survival rate of autologous fat grafting. To enhance the stability and safety of fat grafting, Dr. Chuang employs the closed fat extraction and purification system (Cytori pure graft system) and the combined advanced technology of autologous serum-derived growth factors (commonly called stem cells) to mix with purified adipocytes and then inject them into recipient sites. This closed system not only lowers the incidence of the self-absorption rate after grafting to below 30–40% but also decreases the probability of fat lumping or calcification. Moreover, such a closed system filters out abundant fats within a short time to reduce the surgical time of autologous fat breast augmentation and mitigate the risks of necrosis, inflammation, or infection of fats, thus amounting to this system being one of the safest fat preparation methods in fat grafting surgery.
Dr. Chuang believes that fat surgery is an art on “quantity” and “form” and should be well balanced rather than blindly removing body fats. Therefore, the surgery should proceed from curvature sculpting and relinquish the traditional concept of liposuction for simply fat loss. Only in this way can the surgery better meet the requirements of patients. In addition, numerous new liposuction machines and surgical methods only provide more options of tools for physicians, but the success of the surgery still lies in the exquisiteness and skill of the surgeon rather the device; therefore, Dr. Chuang attaches great importance to the depth, scope, and quantity of liposuction, and combined with his abundant clinical experience and sophisticated devices, he offers safe and effective surgeries to patients undergoing liposuction at WiSH Clinic.
