Axillary odor, commonly known as fox odor, is formed when the sweat excreted by the patient’s sweat glands is broken down by bacteria on the skin surface, mainly Staphylococcus, to produce unsaturated fatty acids. Therefore, the removal and destruction of the sweat glands is the accepted treatment for axillary odor. The sweat glands are located within the dermis or subcutaneous tissue and open to the hair follicles. It is common in young adults, and is an autosomal dominant genetic disorder, which is an obstacle to communication and is easily disliked by others and makes you pessimistic. Therefore, there are many people and treatment methods, and currently the main method of external application of drugs, intradermal injection method, surgery. External application method: commonly used alum, lobster, half-moon clear, bright dew liquid, etc., applied to the axillary local, destroy the hair follicle, so that the follicle hole closed, a short period of time to eliminate axillary odor, because the sweat glands have not been destroyed, easy to relapse, need to repeat the drug. Intradermal injection method: including 95% alcohol, elimination of hemorrhoid liquid, alum plus yellow and other preparations intradermal injection method, local injection, so that sweat gland tissue atrophy, secretion reduction or loss, odor elimination, but the injection of local pain is obvious, the injection is too shallow, can make the skin necrosis, but also can leave the subcutaneous nodules do not disappear. Surgical method: 1, axillary small incision subcutaneous scraping, cut a small mouth, using a metal scraping spoon subcutaneous scraping, destruction of sweat glands, elimination of axillary odor, but the destruction is limited, can not be completely cured. 2, axillary sweat hair area skin excision, for the traditional treatment, the axillary hair area of patients with large, remove more skin, incision suture tension, postoperative skin necrosis, incision cracking, infection, scarring and other complications, thus causing axillary dysfunction. 3, axillary sweat hair area skin excision in situ implantation, the implantation area is thin, the skin is easy to necrosis. In recent years, our department has used small incisions and multifunctional ionization machine to treat more than 100 cases of axillary odor with satisfactory results. The surgical method is described as follows: outpatient local anesthesia. First of all, the axillary skin is prepared, and the extent of the axillary hair is marked along the edge of the axillary hair with Meridian, and a small incision of about 2cm in length is made along the transverse axillary line, which is subcutaneously separated under the skin, and the subcutaneous fat, hair follicles and sweat glands are removed under direct vision with plastic scissors, and the subdermal vascular network is preserved, and the sweat glands and their ducts are further cauterized with a multifunctional ionizer, and the incision is closed in situ and the area is bandaged with pressure. This method is a double destruction of sweat glands under direct vision and electrocautery, so that secretions can not be discharged, eliminating odor, reliable and long-lasting efficacy, using a small incision in the transaxillary line and subdermal vascular network flap peeling technology, the operation is less traumatic, fast recovery, natural appearance of the axillary skin, small and hidden scars. It is superior to all the methods introduced earlier.
