Axillary odor, commonly known as fox odor, is seen in the young and middle-aged period, seriously affecting the patient’s social interaction, learning, employment, love and family life, the formation of huge psychological pressure, so that patients have a sense of inferiority and trauma, seriously affecting the physical and mental health of patients. First, the cause: armpit odor to hot days when sweating is obvious, the sweat discharged by the sweat glands of patients by the bacterial decomposition of the skin surface into unsaturated fatty acids and produce odor. The sweat glands are regulated by endocrine, endocrine exuberance in adolescence, the most obvious symptoms, to be significantly degraded in old age. The disease mostly has a family history of heredity. Second, the treatment: mild axillary odor can be used non-surgical treatment, severe cases need to perform surgical treatment. 1, non-surgical treatment: (1) diligent bathing, diligent change of clothes, pay attention to local cleanliness. External use of ice chips, talcum powder, Xixiang Lanlu, etc., to reduce sweat gland secretion. Externally use 75% alcohol to kill local bacteria. (2) Subcutaneous injection of tretinoin and botulinum toxin in the axillary area to make the sweat glands atrophy and inhibit the secretion of sweat glands. (3) Laser and cryotherapy, which can destroy hair follicles and sweat glands. Non-surgical treatments can only relieve the symptoms. For a complete cure, surgical treatment is required. 2, surgical treatment: At present, surgical treatment is still the most effective and most thorough method. (1) axillary odor stripping: the axillary dermis and fat layer completely separated, cut off the sweat ducts and destroy the glands to prevent sweat discharge. The method does not remove the skin, small damage, quick recovery, light scarring after healing, and better results. (2) axillary odor excision: shuttle excision of skin and subcutaneous tissue in the axillary area, direct suturing. In order not to form a linear contracture scar after surgery, 1 to 2 “Z” flaps can be made. The method is reliable, but the damage is too large, the scar is obvious, affecting the function of the upper limbs. (3) Minimally invasive axillary excision: ① Swelling liposuction method: swelling anesthesia technique is used to aspirate the sweat glands between the dermis and subcutaneous tissue with a liposuction needle. The method has little damage, quick recovery, and no scarring after healing, but the treatment is not thorough enough and easy to recur. ② Spoon scraping method: Using small incisions, the sweat glands are removed by scraping with a spoon or special instrument between the dermis and subcutaneous tissue. This method has little damage, quick recovery, and no scar after healing, but the treatment is not complete enough and is prone to recurrence. (3) Flap transfer method: The skin of the axillary area is cut in a “Z” or “S” shape to form a flap, which is trimmed into a full-thickness skin piece and implanted back in place. The surgical marks of this method are less obvious and the treatment effect is good. ④ Parallel incision and skin flip method: 2~3 parallel incisions are made in the axillary area, about 3cm long and 3cm apart, and the skin is flip to remove sweat glands under direct vision. The method has no obvious surgical marks, has good therapeutic effect, and is our most commonly used surgical method. The more common complications after minimally invasive axillary excision are local hematoma and skin necrosis. Good braking and proper compression bandaging are essential to prevent complications, for which the patient must follow medical advice and work closely with the doctor to achieve good results.
