Suture 

the surgical uniting, chiefly by a surgical needle and suture material, of tissues cut during surgery or separated by an injury. Threads made of silk, linen, or Dacron and other polymeric materials are used in superficial sutures. In buried sutures, which are applied to internal organs and tissues, absorbable materials, such as catgut or biologically inert polymeric threads, are used; buried sutures are not removed.

One type of superficial suture, cosmetic suture, which is applied to the face, is made using threads of horsehair or thin ca-pron. Osteorrhaphy (osteosynthesis) is a type of buried suture. Primary, primo-secondary, and secondary sutures are distinguished on the basis of when the sutures are applied, which depends on the type of wound. The sutureless union of tissues is achieved with various adhesives made from polymeric materials (for example, cyanoacrylate) or with metal clamps.
