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.

Moreover, it had two advantages: first, the coordinate system could be defined easily during the operation because the scalp covering the zygomatic arch, FPZ, SMC, and the mastoid is thin enough to palpate points A, B, and C; second, this positioning system does not need recognition of the cranial sutures (the lambdoidal, squamosal, and parietomastoid sutures) which should be identified for using the traditional method to locate the IMTS.[sup][9]
(1), (2) Cleidocranial dysostosis presents similarly to pycnodysostosis, with persistent open fontanelles and cranial sutures; however, it always involves the clavicle (a bone only rarely affected in pycnodysostosis) (1) and does not result in overall increased bone density.

The cranial sutures are open and normal, therefore conservative management, such as physiotherapy and helmet therapy, is frequently used to treat this condition.
Differential diagnosis should be made to exclude craniosyntosis, which is a more serious condition involving premature fusion of one or more of the cranial sutures. (2) Craniosyntosis usually requires surgical intervention to prevent more serious deformity and possible brain damage.
The cranial sutures are a physiological mechanism designed to accommodate or adapt to the existing anatomical make-up, with or without an imposed strain or restriction being present.

In its classic form, patients experience a premature closure of the cranial sutures, which leads to brachycephaly, proptosis, a small maxilla, and anomalies of the external and middle ear.
