Axillary odor, commonly known as fox odor, is the odor of sweat excreted by the sweat glands (also known as parietal sweat glands) in the skin of the body such as the armpits, perineum and other parts of the body surface by the bacterial decomposition of the skin surface to produce unsaturated fatty acids. Most fox odor has a family history. Most of the onset in adolescence. Seriously affect the patient’s social interaction, study, employment, love and family life, causing psychological stress. Therefore, the treatment of fox odor not only treats the physical discomfort, but also solves the psychological stress. Causes of fox deodorant Causes of fox deodorant causes a variety of causes, generally due to the following: 1, sweat gland secretion, mainly in the palmoplantar and inter-rub areas, sweat is colorless and odorless, often sweating, sweat is decomposed by the skin surface parasitic bacteria release fatty acids, etc. that produce a special odor; 2, fox deodorant and genetic related. Survey results show that both parents suffer from fox, the chances of children suffering from fox odor reaches 80%, if only one side suffers from fox odor, the chances of children suffering from fox odor is 50%. 3, female body secretion sweat glands than men 50% more, mainly concentrated in the breasts, armpits, anus and around the belly button. These sweat glands gather in certain localities, forming a moist and warm environment as a breeding ground for bacteria, producing more bacteria to cause fox odor. People susceptible to axillary odor The incidence of axillary odor in China is 4-8%. 1, young adults, young adults with strong secretion of sweat glands; 2, those with family history, common family genetic skin disease; 3, emotionally unstable people, the sweat glands are controlled by the gonads, hormonal secretion may induce sweat gland lesions; 4, there is no significant difference in the proportion of men and women. Traditional axillary odor treatment methods ① drug external application method, can only temporarily relieve, can not be eradicated, but also appropriate to cause skin allergies, pigmentation; ② instrument cautery method, commonly used laser, high-frequency electroacupuncture, ion cautery, microwave, cryotherapy, etc., the recurrence rate is very high; ③ local drug injection, sclerotherapy injection, can cause local sterile inflammation (redness, swelling, heat, pain, restricted activity), affecting work and study, can not be cured ; ④ skin excision method, which is an ancient method, the local axillary skin with axillary hair all removed, including large and small sweat glands and their normal tissues, although it can be eradicated, but the postoperative recovery time is long, due to tension, postoperative incision cracking, or stitch removal time of more than two weeks, often accompanied by upper limb activity restrictions after surgery, the need to assist functional exercise for two to three months, and the scar is very obvious, difficult to shape, is now less used. The best treatment options for axillary odor 1, minimally invasive deodorization – remove sweat glands thoroughly without leaving marks At present, the best treatment options for axillary odor – minimally invasive peeling of axillary odor that preserves the subdermal vascular network. Through one or two surgical incisions in the axilla slightly narrower than the width of the axillary hair, the flap is flipped, the subdermal vascular network is preserved, and the sweat glands located in the subdermal and subcutaneous layers are trimmed, thus achieving the dual purpose of eradicating axillary odor and leaving small scars in the axilla. Advantages: (1) eradicating the root cause of axillary odor, acting on the sweat glands under direct vision, without destroying other tissues in the armpit; (2) fast and painless treatment, no side effects, and free arm movement; (3) tiny incisions, no scars after surgery and skin folds are integrated, and the skin is naturally beautiful; maintenance time: permanent 2. Botox injection – non-invasive Injections to remove armpit odor is simple and convenient without scars and marks For people who are afraid of surgery and desperately want to solve the problem of fox odor, Botox is the right choice. Botulinum toxin type A injection in the armpit can inhibit the release of acetylcholine from the sympathetic postganglionic fibers that innervate the sweat glands, resulting in the gradual atrophy of the sweat glands in the armpit area and a gradual reduction in sweat secretion, thus achieving the purpose of removing armpit odor. Advantages: (1) Gradual injection point by point, no scar, no discomfort, more relaxed to get rid of axillary odor; (2) fast effect, sweating reduced within 48-72 hours, sweating symptoms significantly improved after a week, odor reduction; (3) no surgery, more convenient injection, no pain, no recovery period, safe and lasting. Maintenance time: 6~10 months. Post-operative precautions ① Strictly brake the upper limbs bilaterally for 48 hours after surgery, put pressure bandage on the axilla, need special attendants to avoid bleeding due to getting up and hand propping and other actions; ② No pain or slight pain in the incision after surgery, if it is very painful, especially bilateral asymmetric pain, need to pay attention to it, contact the surgeon and come to the hospital for follow-up if necessary; ③ Come to the hospital for review 48 hours after surgery, change the medicine, pull out the draining skin piece. Observe the axillary flap blood flow and bruising, check whether there is hematoma, remove it in time if necessary, and continue to put pressure on the bandage; ④ come to the hospital on the fifth day after surgery to review, change medicine, check the axillary flap blood flow, flap fitting, check whether there is hematoma and seroma, if everything is normal, you can sterilize and simply bandage; ⑤ remove stitches 10~12 days after surgery; ⑥ one month after surgery, you can participate in sports.
