Axillary odor, commonly known as “fox odor”, is a form of limited oedema. Most Oriental people are seen with axillary odor, while Western people or black people are seen with sweating. The disease is caused by the secretion of the sweat glands in the armpits, which is decomposed by bacteria and produces odor, which is caused by unsaturated branched-chain fatty acids of six to ten carbons. Although axillary odor does not affect the function of the body, nor does it affect the appearance, but it will affect the work life and social interaction, and will have a certain negative impact on the human psyche, especially the psychology of adolescents. With the continuous improvement of the national standard of living and the increasing attention to psychological problems, axillary odor is receiving more and more attention. The heavy odor causes a serious psychological burden to the patient, but also to the patient’s work and life bring greater impact. Therefore, axillary odor must be cured. Pre-operative preparation Patients are made routine blood tests before surgery, and the results are not abnormal. After washing the axilla before surgery, the patient is placed in a flat position with both upper arms raised and abducted, and the palms of both hands are placed behind the occiput with the elbows bent, so that the axilla is fully exposed. A line is drawn along the axillary hair edge 0.5 cm outside the axillary area, which is the area of axillary subcutaneous peeling. A parallel incision, about 4 cm long, was made along the axillary crease, and the marked peeling area was divided into two equal parts. After the skin is prepared and shaved in the area and surrounding skin, the marked line is fixed with iodine. After successful anesthesia, the skin is incised along the design line and sharply separated at the junction of the subdermis and subcutaneous tissue with anatomical scissors, with the tip of the scissors facing upward, so that the skin flap above the scissors is as thin as possible and the hair follicles and sweat glands are left as much as possible below. remain as much as possible on the underlying tissue flap. The skin is lifted with a pull hook and the scissors are sharply separated on the superficial fascial surface to the drawn line. After sufficient peeling, the long tissue scissors are extended from the lower end of the incision into the subcutaneous superfascial lax space and the tip of the scissors is passed through the subcutaneous tissue at the upper end of the incision. The superficial axillary fascia is picked up with a vascular clamp and pulled upward to reveal a thin layer of fibrous septum at the junction of the superficial and deep axillary fascia, which is sharply separated with small ophthalmic scissors on the deep side of the fibrous septum. During this procedure, attention is paid to hemostasis, and it is observed that the fat particles in the superficial axillary fascia are coarse and yellowish in color, while the fat particles in the deep axillary fascia are fine and white in color, which helps to grasp the level during surgery and avoid damaging the important blood vessels and nerves in the deep axillary fascia. In order to remove the axillary hair and to achieve a complete surgical result, the flap can be further held against the finger and some of the tissue of the sweat glands and hair follicles remaining on the flap can be cut out. Chloramphenicol saline is used to flush the separated cavity, squeeze out the free tissue fragments in the peeling cavity, drain the subcutaneous fluid, stop bleeding thoroughly, and close the incision with interrupted 3-0 silk sutures. Vaseline gauze was used to cover the incision, and 2-4 stitches were sewn on each side of the axillary hair area, wet gauze was packed and fixed, and an elastic bandage “8” was used for external fixation and pressure bandaging. Postoperatively, antibiotics were applied for 7 days and the shoulder was braked for at least 5 days. The compression pack was removed about 5 d after surgery, and the stitches were removed 10-14 d after surgery.
