The choice of incision is important: too large an incision will leave a more obvious scar, while too small an incision is not conducive to the complete removal of sweat glands. Patients who have undergone minimally invasive axillary odor surgery are often seen in the clinic and require another surgery due to residual and recurrence. 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 (one 4cm incision), and then in the microincision method (one 1cm microincision). 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.
