Axillary odor is a thicker sweat excreted by the sweat glands (openings located at the root of the hair follicles), also called parietal glands, which are rich in fatty acids (more than normal people), and is produced by the decomposition of bacteria on the surface of the skin, mainly staphylococci, which produce unsaturated fatty acids and emit an odor. It is also known as fox odor because of its similarity to the smell of fox anal discharge. Because the sweat glands in the adolescent secretion, so the axillary odor is mostly seen in young adults (more women than men), with the growth of age, the aging of the human body, the sweat glands also gradually degenerate, the symptoms can be reduced or disappear, most patients have a family history of heredity. The treatment of axillary odor 1, topical drug application: rubbing antibacterial agent to locally inhibit the growth of bacteria in the armpit; smear adsorbent adsorption formation of fatty acids; rubbing antioxidants to inhibit the formation of fatty acids; apply perfume to cover the odor has been decomposed. Commonly used to apply neomycin ointment, talcum powder, Xishi Lanlu, etc., but these methods are the symptoms of the cure can not last, especially in the heat of the day when the effect of sweating is particularly poor. 2, local injection therapy: axillary subcutaneous injection of drugs to make the sweat glands atrophy, necrosis, inhibition of sweat gland secretion. Such as anhydrous alcohol, formalin, botulinum toxin or elimination of hemorrhoids, etc., but the injection method has the effect of inaccurate, part of the effect of maintenance soon, easy to occur skin necrosis or local painful nodules and other discomfort. 3, physical therapy: laser, freezing, high-frequency electroacupuncture and other destruction of the axillary hair area of the sweat glands, and through the formation of skin scar tissue to block the exclusion of glandular secretion, prompting glandular atrophy. However, the general efficacy is short-lived, the recurrence rate is high, and the scarring is also obvious. 4, traditional surgical treatment: the axillary sweat gland distribution of skin excision, although the efficacy is reliable and thorough treatment of axillary odor. However, the disadvantage is the large trauma, long wounds, because to remove part of the skin, the wound tension when sutured, the wound is easy to crack, easy infection. After surgery, the axilla needs to be bandaged with pressure for more than three days, and the movement of the upper limbs is obviously restricted. The postoperative axillary scar is obvious, and in serious cases, it will affect the activity function of the upper limbs, and the postoperative recovery time is also long. 5.Minimally invasive surgical treatment: Under local anesthesia, one or two (axillary hair, serious axillary odor) 1.5 cm skin incisions are made in the axillary skin, through which small surgical instruments are used to scrape and cut out the hair follicles and sweat glands under the skin of the axillary area to achieve the effect of eliminating axillary odor. This method, with small trauma, short operation time, precise efficacy, appropriate postoperative axillary bandage can be, the upper limb activity is not significantly restricted, the chance of postoperative infection is small, the scar is not obvious, no functional impact, for female patients also has the cosmetic effect of eliminating axillary hair. Therefore, minimally invasive surgical treatment has gradually become the main method of treatment of axillary odor. The distribution of subcutaneous sweat glands varies from person to person, and in a few patients the sweat glands are widely distributed and cannot be completely removed by minimally invasive surgery, so a little odor will remain after surgery, but generally it no longer affects the normal life of the patient.
