Clinical study on the excision of benign breast tumors by paramamammary staged incision

In recent years, due to the westernization of lifestyle and the change of life pressure, the incidence of breast diseases troubling women is increasing year by year, and surgery is one of the most important methods, and the effectiveness of surgery directly affects the treatment effect and women’s physical beauty. Skin characteristics: thin, elastic, stretchy skin in the areola area, with a large push between the areola and the gland, which facilitates the expansion of the surgical field and thus facilitates the surgical super work, less fatty tissue next to the areola, which reduces the possibility of fat liquefaction compared to other incisions, while the pigmentation of the areola and the nodular sebaceous glands of the areola make the scars less likely to appear and achieve a cosmetic minimally invasive effect. The postoperative follow-up results of 208 patients in this study showed normal breast morphology and appearance, and the incision scars were not easily detectable. 3.2.2 Understanding the characteristics of the blood supply to the nipple and areola: the blood supply to the areola mainly comes from the posterior intercostal artery 3-7 of the internal thoracic artery, the mammary branch of the uppermost thoracic artery and the thoracic acromial artery and the external mammary branch of the lateral thoracic artery; the veins are divided into two groups: the superficial group of veins is close to the skin and its position is more superficial than that of the artery; the deep group of veins is accompanied by its eponymous artery; both the superficial and deep groups of veins converge into the axillary vein and the internal thoracic vein. The above branches are interwoven into a network in the mammary gland and together constitute a three-dimensional blood flow system in the mammary gland, especially in the nipple and under the areola there is a vascular network that makes it rich in blood supply, sufficient blood flow reduces the chance of wound infection and facilitates the healing of the parareolar incision, as long as extensive peeling of the nipple, areola and bottom is avoided, it will not cause nipple necrosis, so the parareolar incision is safe and feasible. The postoperative follow-up of 208 patients in this study showed no cases of nipple necrosis. 3.2.3 Pay attention to the anatomical characteristics of the distribution of nerves in the nipple and areola region: the nerves distributed in the nipple and areola region come from the lateral cutaneous branch of the 3rd-5th intercostal nerve and the deep branch that passes through the breast tissue. The lateral cutaneous branch of the 4th intercostal nerve enters the nipple areola region at 4 o’clock in the left breast and 8 o’clock in the right breast, so the lateral cutaneous branch of the 3rd, 4th and 5th intercostal nerves should be avoided as much as possible during surgery. In this study, the lateral cutaneous branch entry position was basically avoided, and there were few patients with postoperative sensory disturbances in the nipple and areola area. 3.3 Surgical points and considerations The humanization of medicine has realized the need to focus on the cosmetic role in breast surgery, so the surgical design should pay attention to the combination of aesthetics and cure [4] [6]. Using the concept of layered surgery, different incisions are selected for operation according to the different anatomical levels of the breast, based on the location of the tumor and the need for surgery, which not only takes into account the cosmetic effect of the breast skin, but also reduces glandular damage due to the use of radial incisions on the surface of the gland to remove the tumor. Extensive peeling of the nipple and areola base should be avoided during the operation to prevent necrosis of the nipple and areola skin. Thorough hemostasis should be noted during surgery to prevent local hematoma formation; in addition, tunneling within the subcutaneous tissue of the breast should be made close to the surface of the gland, but it is less obvious in a small number of women, especially older women with atrophied breast glands (fatty breasts), and skin damage distal to the incision should be prevented. 3.4 Prevention of postoperative skin depigmentation Postoperative depigmentation of the incision site in some patients is mainly due to the thermal damage to the incision skin caused by the heat of the electric knife during surgery, and the heavier the intraoperative thermal damage, the more obvious and extensive the postoperative skin depigmentation of the incision site is. In our study, we used trimming part of the infusion skin strip tube over the electric knife head, so that the knife head only leaves a little does not affect the operation of surgical electroincision can be, while using gauze strips to avoid direct contact between the pull hook and the skin and other measures to reduce thermal injury, and achieved better results. In conclusion, the design and operation of mastectomy through the areola incision can avoid unnecessary damage to the breast, and the postoperative scar is slim and hidden, which enhances the cosmetic effect. It has a certain clinical application value for some patients, especially young beauty-loving women.
