Armpit odor, commonly known as “fox odor”, is caused by various bacteria in the armpit and the organic substances contained in the secretions of the top secretory sweat glands (sweat glands) interacting to produce unsaturated lipid-proof acid. The incidence of national people is about 6%. The diagnosis of axillary odor is based on: 1. family history, one parent usually has axillary odor; 2. cerumen secretion in the form of oil (i.e., oily earwax); 3. self-consciousness or others found to have a significant odor. There are numerous treatment methods for axillary odor. Although the traditional shuttle excision can remove the odor, but the postoperative braking time is long and often leaves an ugly local scar, which does not meet the requirements of modern aesthetics and fast-paced life. Laser, freezing, electrocautery, small incision scratching and other methods have been proven to be incomplete, and after treatment a large amount of local fibrous tissue is formed, wrapping the residual sweat glands, resulting in secondary stripping surgery is not easy to complete. The various topical drugs on the market are only effective for a short time and have a high incidence of skin allergies. Currently recognized as a better and less invasive method is the small incision axillary odor stripping. The surgery takes a parallel incision in the axillary crease, depending on the size of the axillary hair area length 1 to 2 cm, separates and exposes the crystalline sweat glands and hair follicle tissue attached below the dermis, trims and removes them under direct vision, and closes the incision with non-invasive sutures. Compared with other methods, small incision axillary odor stripping has the following characteristics: 1, small surgical trauma, only the targeted removal of odor-causing sweat glands, some hair follicles, retaining the epidermis, dermis and subcutaneous tissue; 2, hidden axillary crease incision; 3, small postoperative scar, the direction of the incision and the axillary transverse line, and are selected 6-0 to 7-0 nylon suture, so the formation of scar is not obvious; 4, braking 5.Fast recovery, two weeks after surgery can resume normal life and study; 6.Less complications, mainly postoperative hematoma, strict postoperative braking can avoid this complication. 7, the exact effect of surgery, where men over 18 years of age, women over 16 years of age, and have not received laser, freezing, electrocautery, small incision scratching and other methods of treatment can achieve satisfactory postoperative results. In short, small incision axillary odor stripping can meet the requirements of the majority of patients with axillary odor “to remove the smell without scars”, is currently the mainstream of the domestic dermatological surgery sector for the treatment of axillary odor.
