Traditional armpit surgery, as the name implies, is a long time ago, but also the treatment of armpit odor can be enshrined in the classic textbooks and surgical atlas of surgery, in the country, the procedure has been verified by several generations of surgeons, became the mainstream of the past decades, and even today is still the majority of domestic public hospitals armpit odor surgery. The defects of traditional surgery need not be repeated, the post-operative scar has become a stumbling block that prevents it from continuing to sing the lead role in the cosmetic industry today, and today I am not here to discuss whether traditional surgery is good or not, because it does not have any advantages in terms of appearance, but I have to cut to the chase and start a new round of thinking about it from the efficacy. The procedure is known simply as excision, which involves making a shuttle-shaped incision comparable to the extent of the axillary hair and moving the skin in its entirety. Theoretically, the procedure does not leave the slightest residue, the sweat glands of all sizes, young and old patients, the efficacy is quite thorough, otherwise it would not have dominated armpit odor surgery for so many years. However, as the procedure has become younger and younger in recent years, and has been widely abused in patients outside of its indications, there has been a large number of “runway relapse” patients. If the axillary area is compared to a standardized stadium, the failed traditional surgery is not designed to excise enough, or the new sweat glands are created later during the development process, resulting in the first surgery only completes the repair of the central soccer green field of the stadium, while the surrounding track is still full of sweat glands and hair follicles, and the axilla is clearly circular with axillary hair surrounding the appearance of the central lamellar scar, which the author calls “runway relapse”. Patients with runway recurrence become the most difficult cases of axillary odor re-operation at present, with residual sweat glands scattered in distribution and no way to operate. Row modified small incision is certainly feasible, but must be laborious to bypass the large subcutaneous scar tissue; do circle up and down the edge of the central two small incision has also been tried, but the incision is too small then can not reach every corner deep; do another traditional surgery has become the choice of some patients, the degree of trauma can be imagined. As a result, we often see such patients in the clinic trying many secondary and even tertiary treatments such as injections and “minimally invasive” procedures, which add to the problem, and the odor is not removed, but the chance of cure is completely lost. One group of patients with runway recurrence is a particularly large range of axillary hair, mostly male patients, and in recent years there is no shortage of girls of this type. The incompleteness of the first surgery is not because the surgeon does not want to do a clean job, but because the excision is too extensive and will inevitably result in an incision that cannot be sutured or will crack after it is barely sutured, so the safe thing to do is to conservatively cut away part of the skin to allow the wound to heal smoothly. Then, because of the amount of basic sweat glands, the number of residual sweat glands is still huge, the odor does not diminish after surgery, and the difficulty of re-operation as described above, the high risk of this part of the patient to seek medical help, rejected everywhere, it is really distressing. So is there really no way out? The author’s clinical experience over the years has confirmed the great risk of surgery for such patients, but it is undeniable that there is still a significant portion of patients with the possibility of cure. The author often says to patients that surgery is difficult, which leaves the surgeon to consider the solution, as the patient just has to figure out if the surgery is worth doing. I do not advocate that patients with mild residuals brave the thunderbolt in pursuit of perfection, but for the truly painful group, a cure is not impossible after a full assessment of the axillary skin conditions and a carefully designed surgical plan and comprehensive treatment program. Believe in Nothing Is Impossible!
