There are many ways to treat armpit odor, and recently many patients and friends have raised many questions and doubts about this. I will give you the choice of treatment methods and personal experience of axillary odor in turn. At present, there are three main treatment methods for axillary odor: botulinum toxin, CO2 laser and minimally invasive surgery. There is a lot of confusion about the choice of method. Which method is effective and suitable? Axillary odor is a common disease in plastic and cosmetic surgery, and the mechanism has not been fully elucidated the histological basis for the occurrence of axillary odor is parietal sweat gland hyperplasia. Removal or destruction of the parietal sweat glands in the axilla is the key to the treatment of axillary odor. The distribution of parietal sweat glands (sweat glands): mainly in the area of axillary hair, the most dense at the central axillary fold, gradually becoming sparse toward the upper and lower ends of axillary hair and the anterior and posterior edges of axillary hair, with a scattered distribution at the periphery. The distribution level: the upper part is connected with the dermal reticular layer and the lower part is closely connected with the superficial axillary fascia. It can be trimmed close to the dermal reticular layer, so that it can be removed cleanly without damaging the dermal reticular layer. The parietal sweat glands form a tough, hard-to-scrape, intact membranous structure near the dermal reticular layer, which needs to be trimmed close to the dermal reticular layer in order to remove them without damaging the dermal reticular layer. This applied anatomical feature determines that surgical treatments such as scratching, liposuction and blind trimming have a certain recurrence rate and more complications. It also shows that the axillary crease incision direct vision trimming method is a generally accepted surgical procedure for axillary odor treatment.
