Abstract:
Six cranial fontanelles are present in newborns along with cranial sutures. Cranial sutures are a synarthrosis type of joints that occur in the skull after closure of fontanelles. Because of ossification up to 24 months, all fontanelles should be closed. Normal frontal bone consists of only frontonasal, frontozygomatic, frontomaxillaris, frontolacrimalis, and main coronal sutures. Metopic frontal suture occurs very rarely in adults. Some metopic frontal sutures might be related to genetic or general disorders or perhaps are related to an improper ossification. In some cases, it persists as a complete suture extending from the nasion to the anterior angle of the bregma, and this condition is called metopism, or metopic suture. In this article, we present a patient with metopic frontal suture diagnosed accidentally during preparation for bimaxillary orthognathic surgery.

01:22Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
01:14Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
01:27Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
