1.The relationship between the choice of surgical method and the signs of facial aging facial aging includes the aging of the whole layer of facial tissue (skin, subcutaneous fat, deep fascia, expression muscle, cranial bone), and the signs of facial aging include wrinkles on the skin surface. The signs of facial aging include skin surface wrinkles, loss of elasticity and sagging of soft tissues throughout the face, and accumulation of tissue in certain areas (nasolabial folds, jawline). Subcutaneous fatty tissue is absorbed and depressed in some areas (temporal and forehead), and thickened and accumulated in some areas (neck and jaw joint, under the chin). The facial contour changes, losing the youthful, beautiful, individualistic and beautiful contours of the past. Therefore, the choice of facial rejuvenation surgery must be based on the signs of facial aging. The small incision minimally invasive method is characterized by small incisions on the skin surface and light trauma, but cannot remove excess skin soft tissue. The large incision (coronal scalp) approach is characterized by a full scalp incision, adequate lifting of the sagging soft tissues, and removal of excess skin soft tissues. It is not possible to exaggerate the advantages of a method and conceal its shortcomings for some reason, applying one method to anyone. Be sure to combine theory and practice to personalize the choice of surgical method. 2.The characteristics of implementing small incision minimally invasive facial rejuvenation surgery and the results pursued according to the latest medical research at home and abroad today: the essence of facial rejuvenation surgery is lifting and tightening, the deeper the level of tissue peeling and loosening, the wider the range, the more thorough the degree, the better the upper body effect and the longer the post-operative effect maintenance time. In order to make facial rejuvenation surgery that has obvious results and a harmonious and natural appearance, and at the same time to minimize the surgical trauma. The characteristics of the small incision minimally invasive facial rejuvenation surgery that I have created and implemented based on the above theory: ① It is very important to choose the right patient. ②The use of small incisions on the skin surface in a minimally invasive way. ③The level of peeling is deep, under the periosteum, and the peeling is extensive to loosen thoroughly, rather than using minimally invasive peeling, so that the whole layer of soft tissue of the face can be lifted and tightened upward. This way, the entire soft tissue of the face can be lifted and tightened upward, not only under the skin. It is like a person wearing multiple layers of clothes, and the layers are bloated, folded and uneven. If we want to smooth out the multiple layers of clothes, instead of sparing them layer by layer from inside to outside, we only smooth out the outer layer of clothes, which is like covering the outer face with a gorgeous dress to cover up, while the inside is still folded and uneven, it will look even more incompatible and uncoordinated. ④Surgery is performed simultaneously with subfacial, supra-neck and sub-chin liposuction, with the aim of removing excess fat tissue under the skin, while allowing the skin and deep tissue trauma to heal and the skin to contract and tighten after healing, restoring the curve of the facial neck and jaw margin in youth. The implementation method pursues the effect of both reducing trauma and ensuring the effect: ① Minimizing trauma where possible, such as using small incisions on the skin surface. ②In order to make the whole layer of soft tissues of the sagging face tighten and reset, and obtain satisfactory results, the deep-level and multi-level peeling and loosening should be thorough, instead of simply suspending for the sake of reducing trauma. ③In order to make the post-operative appearance harmonious and natural (including natural when smiling), the neural connection between the soft tissues (skin and muscles) at all levels of the face must be maintained during surgery, and the connection between them must not be destroyed. 3. Advantages and disadvantages of small incision minimally invasive facial rejuvenation surgery Since it is a small incision, minimally invasive method, the surgery is lightly traumatic and recovery is fast. It can avoid the post-operative complications of large incisions (coronal incisions), such as wider incision scars, hair loss, scalp itching, abnormal sensation, and numbness. You can face the society in about ten days after the surgery. Since the surgery lifts the whole layer of soft tissues of the face at a deep level and preserves the nerve connection between the layers of soft tissues, the postoperative result is both reliable, harmonious and natural. However, this method cannot be suitable for all surgical patients, especially those who make the skin surface wrinkles obvious and want to lift the skin very tightly. Poor elasticity of facial soft tissues and severe sagging are also not suitable for such patients because the small incision minimally invasive method cannot remove excess skin soft tissues. Small incision minimally invasive facial rejuvenation can be performed locally: on the forehead, temporal region, frontal and temporal regions at the same time, in the middle of the face, or on the whole face. The surgical plan can be tailored to the patient’s situation.
