The word sutura is derived from the Latin word sutura, meaning "stitch". Sutura is used to refer to the delicate thread-like stitches used in various medical procedures. Sutura may also refer to the aesthetic effect of these stitches. Sutura can be used to repair various types of tissue, including skin, muscles, and veins. Sutura is also used to modify the appearance of scars. Sutura is composed of a number of thin threads that are tightly bound together. The threads are typically made of surgical thread, silk thread, or even cotton thread. Sutura is often used to close wounds and cover scars.
