What is the primary focus of the worm suture technique?

The primary focus of the worm suture technique is to stitch parallel to the incision. This technique involves creating a series of sutures that run alongside the edges of a wound or incision, which helps facilitate healing and minimizes tension on the tissue. By placing the sutures in this manner, it allows for a more even distribution of tension along the wound edges, promoting better alignment of the tissue layers.

Stitching parallel to the incision contributes to aesthetics in the long term, as it can help reduce scar formation by ensuring that the tissue is aligned properly during the healing process. This method provides effective closure while allowing for potential expansion or contraction of the surrounding tissues without compromising the integrity of the wound.

The other choices relate to different aspects of suturing techniques. While creating a leak-proof closure, accomplishing permanent fixation of ends, and closing long incisions are important goals in various suture methods, they do not specifically define the unique characteristic and focus of the worm suture technique, which is predominantly about the alignment and orientation of the sutures relative to the incision.
