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...

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...
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 Axial Skeleton01:09

Overview of the Axial Skeleton

The skeleton is subdivided into two major divisions—the axial skeleton and the appendicular skeleton. The axial skeleton forms the vertical, central axis of the body. It includes all of the bones of the head, neck, chest, and back. It protects the brain, spinal cord, heart, and lungs. It also serves as the attachment site for muscles that move the head, neck, and back and for muscles that act across the shoulder and hip joints to move their corresponding limbs.
The axial skeleton of the adult...

Summary
This summary is machine-generated.

Atypical sagittal craniosynostosis (ASCS) is a rare complication of common sagittal craniosynostosis (SCS). Early detection and CT evaluation are crucial for managing ASCS and preventing complications like brain compression and developmental issues.

Area of Science:

  • Craniofacial Surgery
  • Pediatric Neurosurgery
  • Developmental Biology

Background:

  • Sagittal craniosynostosis (SCS) is a common condition, typically straightforward to treat.
  • Rarely, SCS can be complex, involving additional suture closures, termed atypical sagittal craniosynostosis (ASCS).
  • ASCS presents diagnostic and management challenges compared to isolated SCS.

Purpose of the Study:

  • To investigate the incidence and characteristics of atypical sagittal craniosynostosis (ASCS).
  • To evaluate the surgical outcomes and long-term results of ASCS.
  • To highlight the importance of advanced imaging and prolonged follow-up in managing ASCS.

Main Methods:

  • Literature review on ASCS.
  • Retrospective analysis of SCS cases treated since 1980.
  • Selection of ASCS cases with metopic or delayed coronal suture closure.

Main Results:

  • ASCS accounts for <10% of SCS cases.
  • In a series of 447 SCS patients, 22 ASCS cases were identified (leptocephaly, oxycephaly, Crouzon syndrome, plagiocephaly).
  • Fourteen ASCS patients required reoperation; 5.3% of SCS cases needed reoperation within 10 years. Long-term follow-up revealed varied morphological outcomes and some patients experienced visual impairment or learning difficulties.

Conclusions:

  • ASCS can be present at diagnosis or develop later in cases of seemingly standard SCS.
  • Leptocephaly represents a distinct subtype of ASCS.
  • Preoperative CT scans and extended patient follow-up are essential for optimal ASCS management and risk mitigation.
