Sutures of the Skull01:22

Sutures of the Skull

The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
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...
Cranial Bones: Superior and Posterior View01:14

Cranial Bones: Superior and Posterior View

The superior view of the cranium shows the frontal and paired parietal bones.
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,...
Cranial Bones: Lateral View01:27

Cranial Bones: Lateral View

The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
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...
Overview of the Skull01:08

Overview of the Skull

The cranium (skull) is the skeletal structure of the head that supports the face and protects the brain. It is subdivided into the facial bones and the brain case, or cranial vault. The facial bones underlie the facial structures, form the nasal cavity, enclose the eyeballs, and support the teeth of the upper and lower jaws.
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...
Structural Joints: Fibrous Joints01:03

Structural Joints: Fibrous Joints

Fibrous joints are a type of joint where the bones are connected by fibrous connective tissue. These joints provide stability and minimal to no movement between the articulating bones. There are three types of fibrous joints.
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

Summary
This summary is machine-generated.

The current Tessier classification for craniofacial clefts is complex and includes non-cleft conditions. A proposed simplified surgical classification uses 4 anatomic regions for easier visualization and treatment planning.

Area of Science:

  • Plastic Surgery
  • Craniofacial Surgery
  • Medical Classification Systems

Background:

  • The Tessier classification is the standard for craniofacial clefts.
  • It is a complex, numerically based system with numerous combinations.
  • It includes conditions not involving true clefts, causing diagnostic challenges.

Purpose of the Study:

  • To propose a simplified, surgically based classification for rare craniofacial clefts.
  • To address the limitations of the current Tessier system.
  • To improve the ease of describing and visualizing craniofacial clefts for surgical planning.

Main Methods:

  • A new classification system was developed, focusing exclusively on true clefts.
  • The proposed system categorizes clefts into 4 types based on anatomic regions: midline, median, orbital, and lateral.
  • It eliminates hyperplasias, hypoplasias, and aplasias from the classification.

Main Results:

  • The proposed classification simplifies the description of craniofacial clefts.
  • It provides a clear starting point for surgical treatment decisions.
  • The 4-type system is based on distinct surgical paradigms for each region.

Conclusions:

  • A simplified, surgically based classification enhances the understanding and reporting of craniofacial clefts.
  • This new system facilitates easier visualization and treatment planning for surgeons.
  • It offers a more accurate and practical approach to classifying these rare anomalies.
