Often in the work of the length of the incision is not satisfied with the removal of a hoodoo-sized swelling, the incision after suturing often need to two centimeters, analysis of the reasons are mainly two aspects, the first is the problem of tension, due to the tension of the skin itself, the removal of 1 cm of the lesion, the wound is often exposed as 1.5-2 cm, which leads to the problem of lengthening of the front, to solve the tension, there are several aspects to think about, the removal of more tissue, or reduce the tension under the skin as well as outside the skin, outside the skin to reduce tension available methods in addition to sutures, there are mechanical methods, such as dressings, dressings and other bonding, can be considered, the method within the skin, then it should be cleverly sutured without leaving a lump, first the mouth becomes smaller, and then off, may be better. The second problem that causes the incision to be long after suturing is due to geometric problems. After excision of the lesion, if no skin implant is placed, the incision is generally oval, before suturing, the length of the incision is the diameter, after suturing, the length of the incision is half the circumference, assuming a positive circle, the length of the scar after suturing is half a multiple of the diameter of the circumference, which is conceivably a factor of 1.57, and this should not be underestimated, regarding the solution of this The disadvantage of this is also obvious. The vertical line incision may become Z-shaped or cross-shaped, and it is often difficult to take care of the direction of the skin lines at the same time for the face. The third thought does not exactly match the title, but is just a question of thinking, reducing the incision is to reduce the chance of infection, and outpatient surgery, perhaps should also adopt the standardized principle of taking drugs half an hour before surgery, perhaps much better than post-operative medication, but the administration of drugs is more troublesome, in addition to the observation of drug-specific reactions led to some risks. There is also the expected problem of skin growth. It is generally found that the healing of different wounds varies greatly, and the healing of areas such as the skin, where the fat is far thicker than the skin, requires special attention, as does the problem of the chest, where the fat itself is less tense and the connective tissue is extremely lax in healing, and where the skin is only so slightly counteracted, obviously difficult to withstand the enormous forces for a short time. In areas where the skin is very thick, healing is not a problem, but scarring is a big problem.
