Armpit odor, also known as halitosis, is because the patient’s armpit sweat glands are more developed, the secretions of the sweat glands are decomposed by bacteria, resulting in an intolerable smell, which is especially heavy in the summer, and in the long run, it affects the patient’s social activities and is easy to form a withdrawn mentality. Currently there are various treatment methods, including: medication, laser, freezing, surgery and so on. Non-surgical treatments tend to treat the symptoms but not the root cause, and are prone to recurrence. Only by completely removing the sweat glands in the armpits through surgery can the root cause of the odor be eliminated, and the root cause of armpit odor can be treated. The goal of surgery for armpit odor is to remove the sweat gland tissue. In particular, the sweat glands. At present, there are mainly the following types of surgery: 1, together with the skin together with the excision method: the target is not strong. Firstly, the amount of skin removed is limited, and the sweat glands in the armpit cannot be removed, so it is easy to recur; secondly, the wound leaves a very long scar, and because of the high tension, the scar tends to proliferate obviously, and restricts the activities of the upper arm, which also seriously affects the aesthetics. 2, skin approach: not remove the skin, but to make a longer incision, by turning the flap, trimming the sweat gland tissue under the skin, often leaving a long scar, there is the possibility of flap necrosis; such as “Z” shaped flap method, parallel incision method, “S” flap method and so on. 3, minimally invasive surgery: (1) suction method; (2) scraping method; (3) sneak clipping method. Principle of minimally invasive surgery: 1, the location of sweat glands is relatively constant, located in the superficial layer of subcutaneous fat, the sweat glands of patients with axillary odor are located in the subcutaneous 1,7~?3,7mm, through minimally invasive subcutaneous clipping way to destroy subcutaneous sweat gland tissues, the treatment of the target is strong, 2, the use of swelling anesthesia technology, which can make the axillary subcutaneous tissues obviously swollen, while axillary nerves, blood vessels are far away from in the deep tissue. Less bleeding and high safety. 3, can better control the thickness of skin trimming: can be completely in the blind removal of subcutaneous sweat glands, hair follicles and the surrounding fat tissue, without the need for a large incision to flip the flap in the direct view of the removal. Advantages of minimally invasive surgery: 1, no hospitalization, simple operation, unilateral surgery can be completed in 30 minutes. 2. No special instruments and materials are needed, and the cost of surgery is low. 3. Easy to take care of, no need to put drainage, no need for fluids. 4. Few complications, basically no scar, suitable for all kinds of people. 5, also has the effect of hair removal, two birds with one stone, especially for young women who love sports and beauty. Disadvantages of minimally invasive surgery: 1, the surgeon needs special training. 2, early upper limb braking. 2. Early upper limb braking, can not be strenuous activities within 1 week after surgery.
