Axillary odor is caused by the abnormal secretion of the top sweat glands in the armpit, and the bacteria in the armpit interact with the organic matter contained in the secretion of the top sweat glands to produce short-chain fatty acids and nitrogen to form the odor. Some scholars have confirmed that the occurrence of axillary odor lies in the abnormality of the axillary sweat glands: large in number, large in size, and vigorous in secretion, even if these patients have the same flora as normal people in the axillary area. Therefore, the complete treatment of armpit odor requires either the elimination of bacteria or the removal of sweat glands. Eliminating bacteria is impossible, and only reducing or removing the sweat glands can effectively or completely solve armpit odor. There are many treatments for armpit odor, including topical medications, laser, freezing, local injections, surgery, etc., and each has its own advantages and disadvantages. Topical medication is a brief inhibition of bacteria or reduce sweating, the symptoms are not the root cause; laser, freezing is through the heat or cold effect will be part of the destruction of the sweat glands, the axillary skin to form a scar to prevent the glandular fluid discharge. Local injection of sclerosing agent can destroy sweat glands and capillaries, so that the tissue undergoes coagulative necrosis and capillary embolism, thus achieving the purpose of treatment. The use of surgery to treat axillary odor is more reliable. Currently more popular is a small incision subcutaneous scraping of sweat glands surgery, because the incision is small, the surgical incision scar is small, but because of the large area of the operation subcutaneous stripping, postoperative reaction, must be pressure bandage, affecting normal work life. The wound is not easy to heal or after healing the armpit is easy to form scars affecting the beauty. Minimally invasive fiber optic treatment of axillary odor; fiber optic minimally invasive dissolution of sweat gland treatment of axillary odor, surgery using only 0.5-0.8mm fiber optic under local anesthesia along the injection of anesthetic needle hole into the subcutaneous, dissolution of sweat glands, surgery time is short patient pain is small. After the operation, axillary odor is basically eliminated and no scar can be seen. Only need to bandage 72 hours, regular oral antibacterial for 3 days can be, without changing medication and removing stitches, immediately after surgery can do general daily work, a week completely this resume normal activities. The advantages of fiber optic minimally invasive treatment of axillary odor; complete removal of axillary sweat glands, almost no scar, short surgery time, surgical safety, small trauma, fast recovery. Almost does not affect normal life and work. Suitable for the fast-paced people now, not only remove the armpit odor thoroughly, but also beautiful, and does not affect the function. Therefore, it is very popular among patients. It is a procedure worth promoting at present.
