Axillary odor is a peculiar odor caused by the decomposition of organic matter in the secretions of the axillary sweat glands by bacteria, resulting in unsaturated fatty acids. It often has a family history of inheritance. Personal understanding of axillary odor should be a reversionary phenomenon, it does not affect physical health and aesthetics, but for the modern society of the family, social normal communication together, the special smell of axillary odor to others with a strong stimulus, unpleasant, affecting with relatives and social interaction. It brings psychological and spiritual pressure to the patient. At present, the main axillary odor treatment methods include: non-invasive and invasive two categories. The most common non-invasive method is topical medication. Mainly for the above-mentioned causes of axillary odor: secretion of sweat glands and bacterial decomposition. Advantages: low cost, no special discomfort (except for a few sensitive skin). Disadvantages: when it is hot, almost every day to use external medication, serious day to use external multiple times. Afraid of the odor coming out. It brings inconvenience to life (for example, “Shonai”). Invasive include: laser treatment (laser hair removal, ultra-pulse CO2 laser), local drug injection treatment (recently popular Botox), surgical treatment of armpit odor. One of the most reliable results should also be the surgical treatment in the radical surgery (axillary odor radical surgery). Simply put, axillary surgery is a surgical procedure that removes as much sweat gland tissue as possible from the armpit to remove the cause of the odor and cure the odor. Difference from traditional axillary odor excision: axillary odor excision is a simple procedure that removes as much axillary skin + subcutaneous tissue as possible, and is closed by direct thick-line reduction or pulling together sutures. Disadvantages: large incision, super long healing time, smooth healing is rare, long-term medication changes are required, postoperative scar healing, upper arm shoulder joint movement disorder, and a high chance of recurrence. This procedure has been eliminated in our department. Pre-operative preparation for axillary odor cure: 1. Pre-operative blood tests, blood clotting time, pre-operative immune system (hepatitis, HIV, etc.), electrocardiogram to exclude contraindications to surgery. 2.No smoking for more than 2 weeks before surgery. 3.Women should have elective surgery from 5 days after menstruation to 1 week before the next menstruation. 4. Patients with a history of external axillary medication should stop applying medication for more than 2 weeks before surgery. 5.Patients with hypertension, heart disease, diabetes, hepatitis, hematologic diseases and other diseases should declare to the doctor in advance to facilitate the treatment. 6.Patients who have a history of taking aspirin, vitamin E, estrogen and progesterone drugs, and Chinese herbal medicine for Qi and blood should stop using them for more than 1 week and declare to the doctor to facilitate the treatment. 7.Shower the day before surgery. No need to shave the armpit hair in advance, and do not pull out the armpit hair to cause local damage. 8.Prepare at least one cardigan loose clothing. Because the arms cannot be lifted up after surgery, so pullover clothing cannot be worn after surgery. Postoperative treatment: After surgery, it is recommended to be admitted to the hospital for 3-5 days for observation, antibiotics, anti-inflammatory, hemostatic drugs to prevent hematoma to prevent infection, “8” elastic bandage appropriate pressure bandage, double upper limb shoulder joints strictly prohibit abduction up (this posture is difficult to take, is the main problem after axillary odor surgery unpleasant). Elbow and wrist joint movement is not restricted. Change the medicine on the first postoperative day with drainage strips, and remove the strips as appropriate. Observe the wound healing. Then change the medication every 3 days. About 2 weeks after surgery, the sutures are removed, the dressings are removed, and both upper limbs enjoy the freedom they had before surgery (personally, I recommend a gradual and progressive resumption of upper arm activities). The wound can be exposed to water the next day after the removal of the stitches, and the wound and the area should not be rubbed hard during the first bath. The incision is hidden in the normal skin line at the top of the axilla, so the scar is not obvious. It is not recommended to perform the traditional excision method that removes all the skin and subcutaneous tissues containing the axillary hair area, because the surgical scar is obvious, the postoperative incision is prone to splitting and it affects the movement of the upper limbs, etc. The application of this procedure is becoming less and less. There are more surgical methods for armpit odor, and there are countless conservative treatment methods (laser hair removal method, Botox local injection method, local anti-sweat, bactericidal drug application, etc.). But there should not exist a way to guarantee that 100% of the armpit odor can be treated. Please consider carefully if there is a “cure-all”, because scientifically speaking there is no recurrence rate is a very unscientific statement. Please be careful and choose carefully.
