Summary
Rare craniofacial clefting patterns reveal most patients have multiple disruptions, not isolated clefts. Midline clefts often extend cranially and are associated with downward clefts, unlike lateral clefts.
Area of Science:
- Craniofacial Surgery
- Medical Genetics
- Developmental Biology
Background:
- Craniofacial clefts are congenital conditions affecting facial structure.
- Rare clefting patterns are infrequently documented, particularly in tertiary care settings.
- Understanding clefting patterns aids in diagnosis and treatment planning.
Purpose of the Study:
- To review and characterize the patterns of rare craniofacial clefting.
- To analyze the association of different cleft types and their distribution.
- To compare clefting patterns in patients with and without features of amniotic band sequence.
Main Methods:
- Retrospective review of patients with rare craniofacial clefts at a tertiary referral center.
- Classification and documentation of cleft types, locations, and associated anomalies.
- Comparison of clefting patterns between patients with and without amniotic band sequence features.
Main Results:
- Isolated rare clefts were uncommon; most patients presented with multiple axes of disruption.
- Midline and paramedian facial clefts frequently overlapped with adjacent clefts and extended cranially.
- Midline/paramedian clefts were consistently observed with their downward axial counterparts; lateral clefts showed diffuse disruption.
- Patients with amniotic band sequence features exhibited more numerous and differently distributed clefts.
Conclusions:
- Rare craniofacial clefting often involves multiple disruptions rather than isolated defects.
- Specific patterns of association exist between different types of facial clefts.
- Amniotic band sequence significantly influences the pattern and distribution of craniofacial clefts.

01:08Overview 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...

01:14Cranial 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,...

01:27Cranial 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...

01:22Sutures 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...

01:03Structural 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...

01:19Cranial and Spinal Meninges
The cranial and spinal meninges are complex protective structures surrounding the central nervous system (CNS), consisting of the brain and spinal cord. These meninges consist of the dura mater, the arachnoid mater, and the pia mater. They protect the CNS, provide structural support, and aid in circulating cerebrospinal fluid (CSF).
Cranial Meninges
These meningeal layers cover the cranium. The dura mater is the outermost layer of cranial meninges. It is a thick and durable membrane of dense...
