Axillary odor, as the saying goes, is called body odor, which gives off a pungent and special smell, which is common in young adults and varies in severity and is hereditary. When you get old, the smell decreases or even disappears. There is no significant difference in the incidence between men and women, and the odor of women before menstruation and during pregnancy is aggravated. The incidence of plastic underarm odor in Chongqing is very low, according to statistics, it is about 6%. In the west, bromhidrosis is very common, and about 90% people have bromhidrosis. Some ethnic groups even have 100% osmidrosis. Most patients with osmidrosis have soft ears in the external auditory canal, commonly known as oily ears. The genitals, anus and areola of a few patients with osmidrosis also have this special smell. However, these patients have no time to care about this, and their main concern is to remove the odor under their armpits. There are many kinds of treatment methods, which can be divided into surgical treatment and non-surgical treatment. Chongqing cosmetic non-surgical therapy includes local cleaning, dry exercise, sterilization, medicine collection, X-ray irradiation, electrolysis, freezing and so on. , generally carried out by dermatologists. Surgical treatment is the most thorough treatment. The root of bromhidrosis is that there are developed sweat glands in the armpit. After its secretion is discharged, it emits a special smell under the action of axillary bacteria. The main purpose of the operation is to remove the apocrine glands during the trip. Apocrine glands are distributed at the junction of deep dermis and subcutaneous fat. The simplest surgical method is to remove the skin and subcutaneous fat in the brigade. The range of excision is the skin of all long hair parts of armpit. The wound can be sutured directly after resection. This method is suitable for small area resection and large area resection. Because of the high tension after suture, the wound is easy to crack, and the scar is large after healing, which affects the appearance. In severe cases, there will be the disadvantages of limited arm lifting, which will affect the function of upper limbs. Although plastic surgeons can use some flap transposition methods to change the tension direction, it will still bring some complications and obvious scars to patients with a large range of armpit hair. At present, Chongqing Plastic Surgery Hospital thinks that the better surgical method is to remove the subcutaneous tissue of the armpit, not the skin of the armpit. The operation process is to make a longitudinal incision in the armpit, lift the flaps on both sides upwards, and remove the fat tissue at the flap with a blade or surgical scissors, but avoid removing the fat tissue in the armpit. After operation, the hair follicle on the flap was removed, so as to completely remove the hair follicle and hair root of axillary hair. At this time, the flap has become very thin. Be careful not to cut the flap too thin to avoid necrosis. Finally, the flap was sutured in situ and bandaged with pressure. Some people apply 25% carbolic acid solution to the inner surface of the flap before suture, then wash it off with normal saline and suture it again.
