The exact cause of axillary odor is not clear, but it is generally believed to be related to abnormal secretion function of the sweat glands. Axillary odor is a common disease, mostly seen in white and black people swell, yellow people incidence is lower, often family onset, to young women common. At present, there are many methods to treat axillary odor, which are divided into non-surgical and surgical therapies according to surgery or not, but most of them are difficult to achieve the ideal treatment effect because the mechanism of axillary odor or the distribution of sweat glands is not clear, or the structure of axillary skin tissue is not clear. We tested the distribution range and level of axillary sweat glands in patients with axillary odor, and found that the breadth and depth of axillary sweat gland distribution is basically the same as the distribution range of axillary hair follicles, and that there are few sweat glands in 0.5 cm outside the edge of axillary hair. The removal of axillary sweat glands is the fundamental method of treating axillary odor. At present, several surgical methods are commonly used clinically: 1, shuttle excision: the method is simple, the effect is exact, but the scar is obvious, and easy to affect the upper limb activities. 2, small incision subcutaneous scratching method to treat axillary odor is in the cut and peel at the same time with a special scraping spoon scratching, can remove sweat glands, fat, hair follicles. However, because the incision is small, the process of removing sweat glands, fat and hair follicles is basically operated under blind vision, and the sweat glands in the superficial layer of fat are not removed, so the removal of sweat glands is not complete, the effect of cure is poor, and the residue is obvious. 3.The S-shaped incision is designed in the middle of the axilla and the flap is turned over to completely repair the sweat gland distribution area into a full-thickness skin slice or a medium-thickness skin slice, which can basically avoid recurrence after surgery, but there is also the problem of not removing the superficial layer of fatty sweat glands, and the incision is easily exposed and affects the beauty. In the case of axillary odor patients, we use axillary wall incision, swelling anesthesia, trimming the superficial fat and a little deep dermis to completely trim the distribution of sweat glands into a full-thickness skin method has the following advantages: 1, swelling anesthesia to make the subcutaneous tissue “thick”, can effectively remove the superficial fat in the large sweat glands 1. Swelling anesthesia makes the subcutaneous tissue “thicker” and can effectively remove the sweat glands in the superficial fat layer, while avoiding damage to the deep axillary tissues; 2. The long incision in the axillary wall is concealed and can fully satisfy the need to flip the flap and trim it into a full-thickness skin piece; 3. This surgical method is effective in treating patients with various degrees of axillary odor, especially those with recurrence after surgery, and can reduce scars to a certain extent and improve the impact on aesthetics.
