Axillary odor is a congenital disease, with a clear family history of inheritance, common in young and middle-aged people, women have a higher incidence than men, and most patients clinically manifest a special odor emanating from the armpits, accompanied by moist external ear canal secretions. The odor is caused by unsaturated fatty acids produced by the decomposition of the secretions of the axillary sweat glands by various bacteria in the area, which seriously affects the social and daily activities of patients at work and in life, and can even damage their physical and mental health. The treatment of axillary odor is divided into two kinds of medication and surgery. Medication can inhibit bacterial activity and reduce the production of unsaturated fatty acids, which can play a certain role for patients with mild symptoms or early onset of symptoms, but medication cannot achieve the purpose of the cure, long-term use of drugs will produce stimulation of the axillary skin, and the appearance of skin thickening and pigmentation and other performance. The principle of surgical treatment is to completely remove the sweat glands in the armpit through surgical means, so as to completely eradicate underarm odor. The traditional axillary odor eradication surgery uses the axillary skin shuttle excision method, along with the sweat glands and skin together with the elimination, the postoperative scar is very obvious, contracture of the scar and even affect the activities of the upper limbs, this method is rarely used. Laser treatment of axillary odor was once popular for a while, but there are disadvantages such as incomplete treatment and dense dotted scar left after surgery, and now it is gradually not accepted by patients. Minimally invasive axillary odor treatment uses a tiny incision of 1-3cm long in the armpit, subcutaneously separating the sweat glands that are distributed under the skin and produce odor, which has the advantages of good surgical results and small postoperative scars. The sweat glands are affected by endocrine activity during puberty, and the onset of axillary odor is also from puberty, so the earliest time for axillary odor surgery is after puberty, and surgery is generally available after the age of 18. Female patients should avoid menstruation, and surgery should be performed only after 3 days of menstruation. Surgery also has a certain seasonality, armpit odor patients in the summer when the odor is significantly aggravated, so most patients choose to treat in the summer, but the best time for surgery for the spring and fall, the summer weather is hot, wound care is more troublesome, winter clothing is too thick, not convenient for wound dressing and dressing, while the spring and fall weather is warmer, the need to wear relatively thin clothing, wound care and treatment Simple and fast recovery after surgery.
