Axillary odor is also known as “fox odor”, its special odor has brought endless distress to many people, but also to work, life and social interaction brought great inconvenience. It is mainly the armpit sweat glands increase, hypersecretion function and the secretions of the sweat glands contain organic matter by the skin epithelial bacterial decomposition effect and produce unsaturated fatty acids and emit an abnormal odor. As the sweat glands are mainly located in the dermis and subcutaneous fat junction, its ducts are mainly open to the hair follicle, so to cure axillary odor we must destroy the sweat glands, or block their secretion pathway that is to destroy the hair follicle. It is related to genetics, about 70% of patients have a family history. There are many treatment methods for axillary odor, mainly: surgery, laser treatment, cryotherapy, high-frequency electroacupuncture, medication and so on. Non-surgical treatment is uncertain, the recurrence rate is high, and surgical treatment is the first choice for its eradication. Traditional surgical methods include pike skin excision, “s” shaped excision, etc., but they are prone to obvious scarring and contracture, scratching and pulling. Since 2005, the use of small incision minimally invasive plastic surgery technique to cure axillary odor has achieved good results. This method is designed to make an incision in the transverse axillary crease in the direction of the skin line, about 2-3 cm long, remove sweat glands and some hair follicles under direct vision, and close the incision with fine stitches, without removing the skin during the operation, with tension-free healing of the incision, small, hidden scar, beautiful appearance, free movement of the axillary skin, good function and few complications. In addition to the good clinical efficacy, for female patients can also play a permanent hair removal effect, can be said to “kill two birds with one stone”. The minimally invasive treatment of axillary odor with small incisions has been well received by patients and is the ideal method for the eradication of axillary odor.
