Breast augmentation surgery has given hope to women around the world who are struggling with flat breasts, and as the safety of the procedure has become more and more specialized, countless female candidates are aspiring to it. Since the surgical incision is the only place where breast augmentation surgery leaves a scar, it is of great concern to many women and is one of the most important elements of concern to plastic surgeons. Currently, the following three incisions are the most commonly chosen in clinical practice. It should be said that each has its own advantages and disadvantages, and needs to be determined according to the objective conditions and subjective requirements of the candidates themselves. (1) Axillary incision: The incision is made through the axillary crease and a tunnel is separated to reach the breast implant placement area. The axillary incision is generally parallel to the axillary skin fold and varies in length depending on the type and volume of the breast implant, usually 4-6 cm. The surgeon will generally peel the deep tissue along the incision to the pectoralis major muscle and then inward to the implant placement. Therefore, the dissection area is relatively large. Advantages: more concealed location, less visible scarring after healing; wider range of people. Disadvantages: The incision to the implant placement area requires a large area of dissection, so there is a lot of damage, bleeding, slow recovery, and a high possibility of implant displacement. In order to prevent the displacement of the prosthesis, it is necessary to fix it with a bandage for a period of time after the operation, and the arm movement will be restricted by pulling. (2) Areolar incision: The incision is made at the junction of the dark and light skin of the areola, either across the nipple or over the edge of the nipple. When this area is chosen for the incision, the surgeon makes a curved 3-5 cm long incision at the edge of the areola (mostly below the areola). If the areola is small, the surgeon may make an additional skin incision next to the areola to ensure a smooth placement of the implant under the pectoralis major muscle. After completing the incision, the surgeon will separate the mammary glands and the pectoralis major muscle vertically downward to create a cavity behind the pectoralis major muscle for placement of the implant. Advantages: dark brown color of the skin in the areola area, less visible post-operative scar, less damage, less bleeding, stable position, short operation time and quick recovery. Disadvantages: During the placement of the implant, the breast tissue needs to be peeled off, which may damage the milk ducts, and in a few cases may lead to breast overflow, affect the healing of the incision, or cause blockage or infection of the milk ducts, although the scar after healing is not obvious. This incision is mostly suitable for women who have already given birth, or who have large areolas and are happy to undergo this incision. (3) Inferior breast crease incision: An incision is made in the inferior breast crease and an implant is placed in the intended location. The length of the inframammary fold incision is usually 3-6 cm, and the incision is mostly located in the center or outside of the inframammary fold. Since there is no breast tissue under the inframammary fold, there is no damage to the breast, and this method is a good way to avoid the milk ducts. The surgeon will go down along this incision and peel directly into the posterior space of the pectoralis major muscle, carefully stop the bleeding and then place the implant. Advantages: the operation is simple, less bleeding, very safe under clear vision, its damage is small, recovery is fast, the position is not easy to move, the biplane operation is very convenient, no damage to the breast tissue, so the patient has no concern that the healing affects breastfeeding; the incision is also very well concealed in the standing position due to the sagging of the breast. Therefore, this incision is the most used abroad, and more and more women in China are choosing it. Disadvantages: For women with smaller and tighter breasts, the degree of breast sagging cannot cover the incision and the scar is more obvious after healing. For women with too little soft tissue, putting in larger implants has the potential for incision dehiscence. Therefore, although the incision is relatively small, it is more suitable for women with moderate sagging breasts that can hide the surgical scar. Of course, no matter which surgical approach you choose, it is always important to choose a guaranteed, regular medical institution and a good, experienced surgeon.
