Axillary odor is a common disease that does not cause direct damage to the body, but patients are in pain and suffer from great psychological stress, which seriously affects their social, work and life. The cause is due to the abnormal secretion function of the sweat glands: large in number, large in size, and vigorous in secretion. The sweat excreted by the sweat glands is decomposed by bacteria and produces odor, so the degree of destruction of the sweat glands determines the effectiveness of the treatment. There are two types of treatment: non-surgical and surgical. Non-surgical treatments include medications, lasers, etc. Due to the deep location of the sweat glands, these non-surgical treatments are difficult to eradicate and have a high recurrence rate. Surgical removal of the sweat glands is the only curative method available. The traditional surgical method is the axillary hair area skin shuttle excision, the operation is simple and has been performed for many years, but there are more disadvantages: 1, leaving an unsightly wide shuttle-shaped scar, some even affect the upper arm activities. 2. Due to the large amount of skin removed, the incision tension is high, and the incision splitting complication rate is high. 3, the scope of excision can not be expanded, and the residual sweat glands appear after surgery, leading to recurrence. Complications of traditional axillary odor surgery: incision dehiscence and striae scarring. This method has long been eliminated and replaced by minimally invasive axillary odor eradication. Minimally invasive axillary odor eradication has revolutionary advances, the advantages: 1, good efficacy: the destruction of sweat glands is complete, the recurrence rate is very low. 2, good appearance: the incision is along the fold traces of the armpit, very concealed, and the scar is not obvious. The principle of surgery is: no skin removal, only skin and subcutaneous separation, destruction of the sweat glands from the inner surface, skin in situ healing. The key point of the surgery is that the removal of the sweat glands should be careful and thorough. Therefore the surgery takes a little more time and after the surgery the skin is bandaged and fixed for a week to allow the separated skin to grow back together with the substrate.
