The incidence of axillary odor (fox odor) has obvious genetic and racial tendencies, with a prevalence of 4.09% in the Han Chinese population and 15.5% in the Uyghur population. In recent years, with the increase of ethnic cultural exchange activities, the number of Uyghur patients with axillary odor has increased significantly. As the number of glands and volume of the sweat glands of Uyghur patients have increased, with reference to the judgment criteria developed by Youg-JinPark and others, they are mostly grade 3 (strong odor is emitted even when they are not active, and can be smelled from 1 or 5m away) with severe axillary odor, and our department has switched to using the swelling anesthesia scraping and suction minimally invasive method to treat a total of 68 cases of severe axillary odor since June 2011, with satisfactory results as follows. 1, materials and methods 1.1, study subjects From June 2011 to February 2012, a total of 68 cases of severe axillary odor were treated, including 51 cases of Uyghur patients, 8 men and 43 women, and 17 cases of Han Chinese patients, 5 men and 12 women. The age ranged from 17 to 39 years old, with an average of 26 years old. All patients had bilateral onset. 1.2. Pre-operative method: Preserve axillary hair, mark the area with a cotton swab of nail violet solution along 2-3 cm outside the range of axillary hair, fix with tincture of iodine, and routinely disinfect the towel sheet. Swelling anesthetic solution configuration: 2% lidocaine hydrochloride 400mg + 1% epinephrine hydrochloride 0,5mg + 0,9% Nacl solution 500ml, bilateral axillary subcutaneous injection of swelling anesthesia, one side injection about 200ml. A longitudinal incision of about 3mm in length was made in the distal part of the axillary area, and the axillary subcutaneous cavity was separated by repeated suction with a suction needle connected to a suction device. Replacing the axillary scraper, repeatedly scrape the axillary sweat gland tissue in different locations under the dermis, with moderate scraping strength, until the skin of the operated area is slightly red or flushed and the axillary hair can fall off by itself, suture the incision, pack the axilla with pressure and fix it with moderate strength, and abduct the shoulders 90 degrees to fix the elastic bandage. The packing was removed 5 days after surgery and the sutures were removed. 2. Results In this group of 68 patients, local skin ulcers appeared in the axillae on 3 sides after surgery, and the wound healed after drug changes. The postoperative follow-up ranged from 2 to 8 months, of which 4 sides still had odor of degree 2, and the rest had no odor residue. All patients had no obvious scar and complications such as limitation of upper limb activities in the operated area, and axillary hair was significantly reduced or disappeared compared with the preoperative period, and all were satisfied with the surgical results. 3. Discussion Surgical operation is the most effective method of axillary odor treatment. The traditional surgical method of removing the skin, subcutaneous sweat glands and subcutaneous fat from the axillary hair area in a wide range of shuttle shape can be cured, but due to the high tension of the skin at the incision, it is easy to cause significant scarring and some even cause limitation of upper limb activities. The modified method includes changing the incision into “Z” or “S” shape, thinning the skin flap and cutting out the sweat gland and hair follicle tissue, but it is inevitable to leave the incision scar, and the complication rate of postoperative hematoma, skin necrosis, delayed healing, scar growth and recurrence of axillary odor is higher. The incision scar is unavoidable, and postoperative complications such as hematoma, skin necrosis, delayed healing, scarring and recurrence of axillary odor have a high incidence, which affects the final outcome. The treatment of axillary odor by swelling anesthesia scraping and suction method can effectively remove subcutaneous sweat glands and destroy hair follicle tissue in the axilla, which has many advantages compared with previous surgical methods, such as thorough treatment, small incision, small trauma, easy and quick, no scar and quick recovery. The treatment results of this group of patients with severe axillary odor show that the efficacy is reliable and the complication rate is low. The key to the operation lies in the degree of skin scraping and suction. In the early treatment of this group of cases, 4 sides were left with different degrees of odor, mainly due to the lack of destruction of the sweat glands (parietal sweat glands). As the sweat glands are mainly distributed in the dermal reticular layer of the skin and the superficial subcutaneous fat layer, the essence of the radical surgery is to scrape and suck the axillary skin flap into a full-thickness skin slice or even a thick medium-thickness skin slice, sharp scraping plus negative pressure suction can precisely treat the symptoms respectively, and more evenly and thoroughly destroy the sweat gland tissue than the traditional cutting method. The initial scraping and suction can feel the subcutaneous roughness and granularity, after repeated scraping and suction, the subcutaneous smoothness and resistance can be reduced, and the slight redness of the skin indicates that the thickness of the skin is nearly full thickness, while the flushing is close to the thick and medium thickness level. After repairing the flap to full thickness or medium-thickness level by traditional surgical methods, the chance of complications such as poor incision healing and skin necrosis will increase significantly after surgery, while one of the major advantages of the scraping and suction method is that the treated skin is still connected to the substrate with a large number of pyknotic fibers, which can provide partial blood flow and also effectively help to fix the skin and substrate and separate the cavity, and none of the cases in this group had drainage placed after surgery but none of them had hematoma or seroma. The effectiveness of this procedure was also demonstrated by the fact that none of the cases in this group had any postoperative hematoma or seroma. In this group of cases, the packing and sutures were all removed 5 days after surgery, which reduced the fixation time of traditional packing, improved the comfort of surgery, and was easily accepted and cooperated by the patients, especially for the Uyghur patients, and is worth promoting.
