Human facial appearances vary greatly not only due to differences in the size, shape, and position of facial features, but also because of the unique variations in facial bone structure. Bones form the framework of the head and face, and their three-dimensional structure determines the overall contour of the face. Among the 21 craniofacial bones closely related to facial appearance, the zygomatic bones and mandible have the most significant impact on facial shape.As a member of the Mongoloid race, the Chinese face generally appears flatter with less three-dimensional depth. Among the more common facial features is a "chubby face." Experts suggest that ultrasound-assisted liposuction can be used to improve facial contours.
Ultrasound facial contouring surgery offers three key guarantees for creating an alluring face shape:
1.Safety
By setting specific frequencies, ultrasound selectively targets low-density fat tissue. This approach helps protect high-density structures like blood vessels and nerves, thereby safeguarding facial nerves.
3. Firming
The ultrasound probe stimulates the inner skin surface. The thermal effect released by the probe causes denaturation and contraction of the subcutaneous reticular fibrous tissue, leading to facial skin retraction.
Specifically, incisions are designed according to cheek and neck wrinkle removal techniques at the surgical site. The skin is incised to separate the skin flap, with the separation layer positioned in the superficial layer of the parotid and masseter fascia and the superficial layer of the superficial cervical fascia.The upper border does not extend beyond the anterior aspect of the zygomatic bone, while the lower border is dissected down to the nasolabial fold region. Approximately 100–150 mL of tumescent solution per side is injected into the fat deposits of both nasolabial folds using a rounded, multi-orifice, non-traumatic needle. A silicone rubber tube matching the probe's diameter is fitted over the ultrasound probe, leaving only 7 mm of the probe exposed.Set to a specific frequency, the ultrasound emulsifies low-density fat tissue. Gently compress to expel as much emulsified fluid as possible while simultaneously stimulating the inner skin surface with the probe to induce skin contraction, achieving a significant liposuction facial contouring effect.
