Axillary odor, commonly known as fox odor or beard odor, is a special unpleasant odor emitted from the secretions of sweat glands distributed on the skin of the body such as the armpits, perineum and back. The incidence of yellow people is about 10%, with a certain genetic tendency. Strictly speaking, armpit odor cannot be considered a disease that does not fundamentally affect physical health, but it is unpleasant to others, affects social life, and even brings mental and psychological stress to patients, and should be treated. The sweat glands secrete unsaturated fatty acids, amino acids, fats and proteins, and the armpits themselves are relatively moist, so bacteria can easily multiply, and the secretions are changed by the action of bacteria, and the intermediate and final products formed are mixed and volatilized. The age of onset of axillary odor is generally more than 18 years old, and after middle-aged and old age its axillary sweat gland secretion function decreases, the odor gradually reduces or even disappears. The most common are young people between the ages of 20 and 30. 【Treatment】 The treatment of axillary odor can be divided into two categories: non-surgical and surgical. Mild axillary odor does not require surgery. Non-surgical treatment includes: aroma covering, topical drugs to inhibit sweating or local sterilization, laser, microwave, high-frequency electroacupuncture, freezing, etc. Only for mild axillary odor, the disadvantages are shorter duration, easy recurrence, incomplete treatment, larger scars and unsatisfactory results. Surgery can directly destroy or remove the axillary sweat glands, which can theoretically achieve relatively complete treatment of fox odor. Including: cut (axillary skin excision), suction (axillary suction), scraping (axillary scratching), clipping (small axillary incision blinded sweat gland trimming), peeling (axillary odor stripping), clearing (minimally invasive axillary odor removal), etc. The above methods have their own advantages and disadvantages. Surgical treatment is a more thorough method, a method is to remove the skin containing axillary hair and local subcutaneous tissue together, the wound to do “Z” shape suture; this method of treatment is reliable, but the scar left after surgery is too large, most female patients are difficult to accept. Another easy and effective surgical method is the small incision minimally invasive axillary odor removal plastic repair. The advantages of minimally invasive axillary odor removal and repair surgery are: small trauma, fast recovery, hidden scars; three benefits in one stroke (odor removal, sweat removal, hair removal); avoiding the shortcomings of simple excision with large excision range, trauma and certain impact on function, and achieving more thorough removal of axillary sweat glands to avoid recurrence of axillary odor. Due to the complexity of human skin tissue, it is difficult to remove every sweat gland through surgery, but most sweat glands can be removed or destroyed more completely, and the symptoms will be significantly improved after surgery. It is a popular surgical procedure for all patients with axillary odor, especially for women who are concerned about the aesthetic impact of excessive scarring. The procedure takes about half an hour to forty minutes and usually requires a week of rest. Precautions: 1. Before treatment, take a shower and change into clean and loose clothes. For the purpose of judging the scope of surgery, it is best not to shave the axillary hair; 2. After surgery, the operated area is bandaged with pressure, the shoulder joint is braked, the upper limb cannot be lifted more than 90 degrees, and strenuous activities are avoided to prevent the occurrence of hematoma, and the patient has slight pain after surgery. Plastic surgery principles and techniques to rectify axillary odor, easy surgery, postoperative scar is not obvious, the effect is ideal, but a very small number of patients still have a small amount of odor residue after surgery. Indications Applicable to all patients with axillary odor, especially female patients who are concerned about the impact of excessive scarring on aesthetics. Contraindications 1.Psychological disorder or unrealistic pursuit. 2.Local rupture and inflammation. 3, poor general condition.
