Fox odor is a kind of body odor, the smell is heavy to make the next person feel uncomfortable. According to statistics, up to 80% of European and American people have fox odor, while the Oriental people are less about 10%. However, Westerners think this is a common physiological phenomenon and do not care. Although the Oriental society has less fox odor, it is always embarrassing for the people involved. What are the causes of fox odor? Generally speaking, there are two types of sweat glands, one is the exocrine gland, also known as the small sweat gland, which is located 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, which is located in the dermis of the skin and opens at the root of the hair, only in the armpits or pubic area and eyebrows, and secretes a thicker liquid containing oil, protein and iron. The sweat is decomposed by the bacteria in the armpit, forming a bad odor. Most fox odor occurs during adolescence and is influenced by emotions and hormones. And fox odor will be inherited, according to the survey, both parents have fox odor will have 80% will be inherited, if only one parent has fox odor, then the chances of inheritance is 50%. As in adolescence, for their own fox odor, the formation of mental pressure, anxiety and frustration, and then the formation of social barriers, a serious impediment to the development of normal personality. Treatment of fox odor is as follows: 1, negative treatment: often keep the underarm area dry, choose a cool place to reduce sweating, do not be anxious and nervous in daily life. In addition, use Fisudermet, Savlon, Epidermolone and other clean skin to avoid bacteria to do accomplices. Of course, you can use perfume or prickly heat powder to reduce the smell, but the effect is not easy to last. 2, drug therapy: antiperspirant and deodorant, theoretically feasible, but in fact the effect is limited, because as long as a sweat, will be lost to the pharmaceutical, and only temporary effect, and pay special attention to the side effects of drugs. 3, electrocautery: with a very fine electrocautery needle, selectively inserted into the hair follicle and the nearby acroplasmic glands, and then pass a high-frequency current to generate thermal current, resulting in thermal coagulation to destroy the hair follicle and acroplasmic glands. This method can reduce the odor a little, but because the location of the hair follicle and the acinar gland is easy to grasp, the effect is not sure, and must spend a lot of time, the chance of recurrence is also quite large. 4.Surgical excision (active treatment): Pre-operative preparation Patients are made routine blood tests before surgery. The patient is placed in a lying position with both upper arms raised and abducted, and the palms of both hands are placed behind the occiput with the elbows bent, so that the axilla is fully exposed. A line was drawn along the axillary hair edge 0.5 cm outside the mark, which was the area of axillary subcutaneous peeling. A parallel incision, about 3-4 cm long, is selected along the axillary crease between them. After successful infiltration anesthesia, the skin is incised along the design line and sharply separated at the junction of the subdermis and subcutaneous tissue with ophthalmic scissors so that the overlying skin flap is as thin as possible and so that as many hair follicles and sweat glands as possible remain on the underlying tissue flap. The skin is lifted with a pull hook and the scissors are sharply separated on the superficial fascial surface up to the drawn line. After sufficient peeling, long tissue scissors are extended from the lower end of the incision into the lax subcutaneous subfascial space and bluntly separated, and the tip of the scissors is passed through the subcutaneous tissue at the upper end of the incision, and the superficial subcutaneous fat layer containing the hair follicles and sweat glands is incised under the protection of the tissue scissors up to the superficial deep axillary fascia. A thin layer of fibrous septum can be seen at the junction of the superficial axillary fascia and the deep axillary fascia. The superficial axillary fascia is lifted from the superficial surface of the deep axillary fascia and completely removed from the axillary area. During this procedure, attention is paid to hemostasis. It can be observed that the fat particles in the superficial axillary fascia are coarse and yellowish in color, while the fat particles in the deep axillary fascia are fine and white in color, which helps to grasp the level during the operation and avoid damaging the important blood vessels and nerves in the deep axillary fascia. The flap is held against the finger and the remaining sweat glands and hair follicles are partially removed. Physiological saline is used to flush the separated cavity, squeeze out the free tissue fragments in the peeled cavity, drain the subcutaneous fluid, stop bleeding thoroughly, and close the incision with interrupted 3-0 silk sutures. Vaseline gauze was used to cover the incision, and 4 stitches were sewn on each side of the axillary hair area, packed and fixed, and wrapped with an elastic bandage with “8” external fixation and pressure. Oral antibiotics were given for 7 days after surgery, and the shoulder was braked for at least 5 days. About 5 days after surgery, the pressure pack was removed, and the stitches were removed in 7 days. The key to radical axillary odor surgery is the complete removal of the sweat glands. Histological studies by the Korean scholar Byeon et al. showed that the sweat glands are located mainly in the subdermis to the subcutaneous fat layer range, mainly in the central area of the axilla. Histological studies conducted by Nikki scholars on axillary odorosis also concluded that the axillary odoriferous glands are located in the range of 1.7-3.7 mm below the epidermis and are located deeper. Domestic embryological studies have proved that the sweat glands are similar to the sebaceous glands, both originate from the primitive epithelial germ, occurring from the epithelial cells of the hair follicles do not open directly on the skin surface, but above the opening of the sebaceous glands, open to the hair follicles, the location of the glands is deeper, generally in the superficial layer of subcutaneous fat. From the above studies, it is clear that sweat gland scraping and sweat gland clipping methods, for example, cannot remove deeply located sweat glands; and swelling aspiration methods cannot effectively remove sweat glands that are closely adhered to the dermal reticular layer. The above commonly used minimally invasive surgical methods are unable to truly remove the sweat glands anatomically and thoroughly, and are prone to odor residue. Therefore, to completely remove the sweat glands, it is not enough to scrape or cut out the subdermal layer or superficial subcutaneous sweat glands, but the superficial axillary fascia layer under the axilla must be lifted up from the superficial surface of the deep axillary fascia. This surgical method achieves the deepest anatomical level of all methods, and I believe that the small axillary incision minimally invasive hair follicles – sweat glands – superficial axillary fascia layer. The composite tissue flap peeling method for axillary odor is the most thorough method to remove the sweat glands.
