Armpit odor surgery refers to the treatment of armpit odor through surgical means. Axillary odor surgery is divided into traditional axillary odor surgery and minimally invasive axillary odor surgery. Traditional axillary odor surgery is mainly through Z- or S-shaped incisions for removal of sweat glands, while minimally invasive axillary odor surgery incisions are much smaller than traditional surgery, usually 3-5mm incisions. The following is how to choose a minimally invasive axillary odor surgery incision: 1, the choice of incision is very important: the incision will leave a more obvious scar, and the incision is too small for the complete removal of sweat glands. In the clinic often see patients who have had minimally invasive axillary odor surgery, due to residual and recurring requirements for surgery again. 2, to ensure the radical cure of axillary odor based on the selection of the smallest possible incision: We started with the double incision method (two parallel 4cm incisions), to the single incision method (a 4cm incision), and then in the micro-incision method (a 1cm micro-incision). After exploring various incisions, the compromise small incision method (one 2.5 cm incision) was finally chosen. After years of clinical practice, this small incision method effectively inherits the advantages of double incision and single incision that can cure axillary odor, and avoids the disadvantages of microincision method that can easily cause residue, and has become the mainstream of the current surgical program with minimal scarring and almost no recurrence.
