Etiology: axillary odor, also known as fox odor, also known as ophidrosis, is caused by the decomposition of organic matter in the secretions of the sweat glands in the armpits, vulva, corners of the mouth and other parts of the patient’s body by bacteria, producing unsaturated fatty acids, which can emit a special unpleasant odor. Axillary odor is more common in adolescence, especially in women, and in middle and old age, as the function of the top sweat glands in the armpits decreases, the amount of secretion decreases, the odor will gradually reduce or even disappear. Genetics: Armpit odor often has a family history of genetics, but also closely related to ethnicity, national and dietary habits. According to statistics, the incidence of axillary odor in Han Chinese is low, about 6%. While in the Western species armpit odor is more common, about 90% or more. Axillary odor is more common in people who eat mainly meat than in those who eat mainly vegetarian food, and with the change in the dietary structure of our residents, the incidence of axillary odor has a trend of increasing year by year. Impact: Although axillary odor does not cause harm to human health and does not affect the aesthetics, but axillary odor produces unpleasant and irritating odor often makes others and even themselves unhappy, affecting social interaction and family life. Armpit odor often brings serious mental stress and psychological problems to patients. Treatment: non-surgical and minimally invasive surgery, surgical treatment Non-surgical treatment 1, external application of antiperspirant lotion: through the physical effect of relieving excessive sweating, can reduce body odor and relieve symptoms. This method is suitable for people with lighter body odor and younger age. 2, botulinum toxin injection: botulinum toxin is very effective in inhibiting the secretion of nerve cells of the nerve conduction substance acetylcholine, so it can well inhibit the excitability of sympathetic nerves that govern the sweat glands and promote sweat secretion by sweat glands. The secretion of sweat glands in our body is also controlled by sympathetic nerves through the use of acetylcholine as a conductive medium. Many patients do not sweat when they are sleeping, resting, relaxing, and other times when the sympathetic nerves are not excited. When they exercise or are stressed (sympathetic excitement), they will sweat. Therefore, local injection of botulinum toxin in the armpit can achieve a good effect of anti-sweating, and the odor in the armpit will be removed because the bacteria will no longer decompose and produce odor when there is no sweating. This method is suitable for those who do not receive surgical treatment and have no recovery time, as well as for those who are younger than 18 years old and have not fully developed armpit odor, and for young and unmarried patients who do not want to leave scars. Cost: Domestic 2500/100u, imported 4500/100u, according to the individual differential service is generally selected 100 ~ 200u Effectiveness: After the injection is generally about 5-6 days to see the effect, can be maintained for 6 months to half a year. You can arrange the injection time according to your actual situation, and you can choose to inject in the sweaty summer. No recovery time is needed after the injection, and you can leave after the injection without affecting your normal work life. Contraindicated groups: people with severe muscle weakness, people with neuromuscular diseases, people with allergies, pregnancy and breastfeeding, people with a history of alcohol consumption within a week, people using aminoglycoside antibiotics (such as gentamicin and streptotoxin), people with mental abnormalities and poor self-control, people with serious heart, liver, kidney and lung diseases or connective tissue diseases. Minimally invasive surgery Fiber optic lipolysis: the plasma laser technology, through a small metal catheter, the fiber into the axillary sweat gland area, stimulate the laser beam, through the mechanical effect of laser, photothermal effect, light stimulation effect, selective destruction of subcutaneous sweat glands and part of the hair follicle tissue, so as to achieve the effect of inhibiting sweat gland secretion, treatment of axillary odor. This method has a lower cure rate than surgery and can remove about 60% of the sweat glands, so it is suitable for those with mild symptoms and those who are younger or do not have time to rest. General: Minimally invasive surgery, the surgery takes about 40 minutes, the surgical incision is only 12.5px, no need to remove stitches after surgery, it does not affect normal study and work, oral antibiotics can be taken for 5 days. The cost of surgery is 15000/bilateral. Surgical treatment 1, small incision hollowing primary surgery: through the surgical way to separate the dermis and subcutaneous fat layer of tissue, cut off the sweat glands and ducts, to prevent sweat discharge to achieve the purpose of treatment. The surgical method to remove armpit odor is more thorough and adaptable to various degrees of armpit odor. Surgery: The surgery takes about 1 hour, routine blood sampling and coagulation tests can be done before surgery, the wound is generally 4~125px long, the post-operative period needs to be braked for 12 days (after the surgical site is bandaged to minimize activities), the stitches are generally removed in about 12 days, the stitches can be removed 3 days after normal bathing, and the activities can be gradually increased after surgery. Since the surgical wound is in line with the skin pattern, the postoperative scar is not obvious. A week after the stitches are removed, anti-scar medication is used to prevent scar growth. The current cost of the surgery is 6000/bilateral. This method is the surgical method chosen by most patients. 2. Sweat gland excision: The main part of the skin and subcutaneous tissues in the axillary hair area will be removed in a diamond or S-shaped excision by surgical means, which can remove the subcutaneous sweat gland tissues and thus achieve the treatment purpose. This method can completely remove the sweat gland tissue, and the postoperative results are better. However, this surgical method has a large area of damage and a large postoperative scar, so it is generally not an option for patients. The actual fact is that you should always go to a regular hospital for any kind of treatment, as incorrect treatment will hurt your life and affect your regular treatment later on. It is important to emphasize that patients who have undergone axillary odor in outside hospitals come to our department for treatment again, the cost of surgery is increased. So, be sure to choose the regular channels of treatment. I wish you all away from the misery of armpit odor as soon as possible.
