“Armpit odor” is also called fox odor. General fox odor patients have two main distress: one is sweating, the second is the smell. Abnormal odor, strong people feel breathless, often retreat; and armpit sweating, even if there is no odor, often due to sweat like a spring, soaked shirt, so that you “raise your hands and feet” between all leak embarrassment. Therefore, armpit odor often makes people afraid of the scene, fear of the crowd, resulting in a huge psychological burden. The occurrence of axillary odor is closely related to endocrine, mostly in adolescence, with the majority of women, to reduce or disappear in old age. Some of them have a family history, which may be related to heredity. The incidence of axillary odor varies according to race (like the indigenous people of Guangdong and Guangxi in China, like Pakistani Indians abroad), individual and hygienic habits, and its degree varies according to season (summer) and climate. At present, there are many clinical treatment methods for axillary odor, which can be broadly summarized as conservative therapy and surgical methods: conservative therapy mainly includes: topical medications, injections and physical therapy (microwave, freezing, electrocoagulation, laser, isotope), aluminum sulfate solution can relieve odor, but it is more irritating to the skin, subcutaneous injection of botulinum toxin can inhibit the secretion of various sweat glands. Surgical methods, there is the traditional axillary skin excision method (the method is simple and crude, leaving obvious scarring, firmly reject!) The most scientific method is the minimally invasive surgical method. Now the non-surgical and surgical treatments are introduced to one each: 1, surgery: surgery is currently the best method of treatment of axillary odor. (1) peel method, is to make an incision in the armpit, peel the skin away, and then cut out the sweat glands, this method is a qualitative leap compared to the cut skin method, is based on a full understanding of the pathogenesis of axillary odor and skin tissue anatomy. This method is a qualitative leap forward compared to the cut skin method, and is based on a full understanding of the pathogenesis and skin tissue anatomy. (2) Minimally invasive method, is the current medical institutions to promote the name more “minimally invasive intervention, minimally invasive scratch ……” principle and stripping method is similar, mainly to make small incisions 1-2cm, the use of surgical instruments to strip the axillary skin, the sweat glands will be destroyed. The advantages are that the incision is short and the cosmetic effect is good. The disadvantage is that it increases the difficulty of operation, blind operation, may damage small blood vessels, resulting in the formation of hematoma. 2, botulinum toxin A injection method: sweat mainly from the sweat gland, its secretion by the nerve command. The nerve mainly through the acetylcholine signal soldier to play a role, the acetylcholine sniped away, will undoubtedly make the nerve regulation sweat gland function paralysis. This is where the familiar face slimming injection, botulinum toxin BTX-A, comes into the picture. BTX-A inhibits the release of acetylcholine from the cholinergic autonomic nerve, producing the same effect as blocking the neuromuscular junction. In patients with hyperhidrosis, BTX-A injections inhibit the longer-term, but reversible, local release of acetylcholine, blocking sweat gland secretion. A surprising result emerges, although Botox does not inhibit the function of the sweat glands, the lack of sweat reduction improves the microenvironment of the armpit, allowing a significant reduction in bacterial colonization so that the various secretions in the armpit (containing various proteins, carbohydrates, ammonia, lipids and iron) are not broken down by bacteria, which then reduces armpit odor to varying degrees. Therefore, those who are afraid of surgery or do not have enough time to deal with the recovery period of surgery can choose the Botox method of injection for relief.
