Armpit odor, also known as fox odor, is a kind of body odor with a heavy taste that easily makes bystanders feel uncomfortable. According to statistics, up to 80% of Europeans and Americans have bad breath, while Oriental people are less, about 10%. However, Westerners consider this to be a common physiological phenomenon and do not care about it. Although the Oriental people have less body odor, they always smell it, which makes the person concerned embarrassed. What are the causes of bad breath? Generally speaking, there are two types of sweat glands, one is the exocrine gland, also known as the eccrine gland, which is distributed throughout the body and secretes 99% of water and 0.5% of salt. The other is the parietal gland, also known as the sweat gland, located in the dermis of the skin, opening at the root of the hair, only distributed in the armpits or pubic area and eyebrows, will secrete a thicker liquid, containing sebum, protein and iron. It is then broken down by the bacteria in the armpits to form a bad odor. Fox odor is hereditary and is associated with gender and racial differences. It is related to the physiological structure and function of the sweat glands. As the sweat glands secrete exuberantly during puberty, the disease is mostly seen in young adults, and as the body ages, the sweat glands gradually degenerate, and the symptoms can be reduced or disappear. Most patients have a family genetic history. Traditional armpit odor surgery – skin sweat gland excision The procedure will cut off the entire skin of the armpit with hair, subcutaneous fat, although the removal of all sweat glands on the axillary skin, the efficacy is reliable, can completely cure armpit odor, but the damage is too large, resulting in local skin defects, and more bleeding. Due to the suture skin tension, limiting the function of both upper limbs, easy to cause wound infection, suture dislodgement, resulting in large surgical scars, affecting the function of upper limb activities. “Emerging” armpit deodorant surgery – minimally invasive treatment of armpit deodorant In recent years, a number of hospitals have carried out armpit deodorant treatment, and crowned with “nanometer”, “Korean”, In recent years, a number of hospitals have carried out axillary deodorant treatment surgery and labeled it as “nano”, “Korean”, “scarless”, etc., which makes patients feel that it is profound. In fact, the main surgical method is to send the suction device into the subcutaneous through a small incision, and remove the subcutaneous fat by repeated scraping and suction. The incisions are small, but not minimally invasive. Surgeons know how traumatic repeated scraping within the tissue can be. Moreover, the procedure is poorly performed and has a very high rate of postoperative recurrence. This is because large sweat glands cannot be removed by scraping. The surgery is suspected of claptrap and self-deception. Radical surgery for axillary odor The surgical incision for axillary odor is located in the axilla, which is more hidden, and if the incision is completely along the dermatoglyphics, it can achieve a good cosmetic effect. Based on this concept, we believe that there is no need to make the surgical incision for axillary odor “tiny”. Instead, we make a pike-shaped axillary incision (following the dermatomal line) and remove about 1cm of skin and 4cm of skin. The purpose of the skin excision is to prevent postoperative skin laxity and to remove some of the sweat glands. The superficial adipose tissue was excised with an ultrasonic scalpel by freeing the deep side of the dermis to the edge of the hair area. The flap was turned over and fat particles and hair follicles on the dermis were removed with ophthalmic scissors. The skin is sutured intradermally. There is minimal bleeding throughout the procedure, the flap has a good blood supply, and the skin is sutured without tension. The skin is sutured without tension. The flap is bandaged with an “8” bandage and the sutures are removed 2 weeks after the operation.
