Axillary odor is an odor of the axillary sweat glands (parietal sweat glands), also known as axillary hyperhidrosis, because the axillary area emits a special pungent odor, and the body odor of the fox is similar, so commonly known as “fox odor”, the clinical common. The top sweat gland is composed of secretion and ducts, secretion sites in the subcutaneous fat layer, its secretion is mainly affected by sex hormones, puberty secretion is strong, so axillary odor more in puberty began to appear, more female patients. When the summer heat is more obvious, the symptoms can be reduced in old age. The occurrence of axillary odor is related to race, climate change, genetics and other factors, often with a family history. Pathogenesis: 1. When there is a lot of fluid and cannot be washed in time, the bacteria on the skin surface can break down the keratin layer impregnated with sweat, thus emitting odor; 2. Sweat secreted by the sweat glands (parietal sweat glands) can be decomposed by bacteria to produce low-chain fatty acids and ammonia and other substances with a strong odor; 3. Bacteria play an important role in the pathogenesis. Axillary odor brings great inconvenience and heavy psychological burden to the patients’ life, study and social activities. So many patients are extremely anxious to cure axillary odor, so they try various treatment methods, such as: topical antiperspirant or cosmetics, subcutaneous injection of sclerosing agent in the axillary area, laser microwave cautery, botulinum toxin injection, various minimally invasive small incisions for surgical excision and so on. This makes patients endure the pain of various treatments and repeat the costs due to the poor results, while constantly dealing with various frequent post-operative complications – yet most of the results are unsatisfactory, which is not really complimentary!
