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.

The skulls were studied for the presence of complete metopic suture.
RESULTS: Among the 100 skulls, complete metopic suture was found in only 3 cases.
DISCUSSION: In the present study metopism or metopic suture was found in 3% cases.

A note on the morphology of the metopic suture in the human skull.
RESULTS: Among the 126 human skulls included in this study, 80 (63.49%) skulls did not show any metopic suture in any form.
Complete metopic suture i.e., metopism was found in 4(3.17%) skulls and incomplete metopic suture was seen in 42 (33.33%) skulls.
In the present study, the linear subgroup of incomplete metopic suture is found to be 16.66% which resembles the findings of Shanta Chandrasekaran et al (2010) and Chakravarthi K.K et al (2012).We found 12.69% of U shaped incomplete metopic suture which is in between the findings of these two workers who found it to be 15% and 10% respectively .Our finding of V shaped incomplete metopic suture to be 3.96% is quite similar to the findings of Agarwal et al (1979) who found it to be 3.25%.

The metopic suture is found between the tubers of the frontal bone, and undergoes intramembranous ossification from two primary centers, one from each half, that appear by the end of the second month of fetal life (Gray, 1988) and fuse first at the inner face of the skull (Moore, 1994), with the closure provided by chondroid tissue (Manzanares et al., 1988).
The period of maintenance of sutures in general has been suggested as a pre-condition for the continuous growth of the bones (Watzek et al., 1982) and as an indirect factor for the normal growth of the skull (Hinton et al., 1984 apud Manzanares et al.), because of that the early closure of the metopic suture results in cranial morbid deformities known as scaphocephaly (Plese et al.,1990; Moore).
