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...
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 and Spinal Meninges01:19

Cranial 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...
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...
NMR Spectroscopy of Benzene Derivatives01:37

NMR Spectroscopy of Benzene Derivatives

Simple unsubstituted benzene has six aromatic protons, all chemically equivalent. Therefore, benzene exhibits only a singlet peak at δ 7.3 ppm in the 1H NMR spectrum. The observed shift is far downfield because the aromatic ring current strongly deshields the protons. Any substitution on the benzene ring makes the aromatic protons nonequivalent, and the protons split each other. The peak is, therefore, no longer a singlet and the splitting pattern and their associated coupling constants depend...

Summary
This summary is machine-generated.

Mercedes Benz pattern craniosynostosis, a rare condition involving multiple suture fusions, requires skull lengthening surgery. Postoperative growth may be diminished, necessitating overcorrection and routine MRI for associated cerebellar tonsillar herniation.

Area of Science:

  • Craniofacial Surgery
  • Pediatric Neurosurgery
  • Medical Genetics

Background:

  • Complex craniosynostoses involve multiple suture fusions, with the Mercedes Benz pattern (sagittal and bilateral lambdoid sutures) being a rare subset.
  • This pattern represents a small fraction of craniosynostosis cases, highlighting the need for specific understanding and treatment strategies.

Purpose of the Study:

  • To review a series of Mercedes Benz pattern craniosynostosis cases.
  • To identify associated anomalies and genetic syndromes.
  • To assess surgical treatment outcomes and long-term growth patterns.

Main Methods:

  • Retrospective clinical outcome assessment of patients with Mercedes Benz pattern craniosynostosis.
  • Anthropometric measurements for growth assessment and statistical analysis using the t-test.
  • Preoperative imaging for anomaly detection, including cerebellar tonsillar herniation.

Main Results:

  • 1.4% of craniosynostosis patients (11 of 802) presented with Mercedes Benz pattern synostosis over 17 years.
  • Associated anomalies included additional sutural involvement (3 patients) and genetic syndromes (2 patients).
  • High incidence of cerebellar tonsillar herniation (64%) requiring Chiari decompression in symptomatic cases (36%); diminished postoperative growth (brachycephaly, reduced head circumference/skull length) observed.

Conclusions:

  • Surgical treatment should prioritize skull lengthening over reduction for Mercedes Benz pattern craniosynostosis.
  • Consideration of overcorrection is suggested due to observed diminished postoperative growth.
  • Routine MRI is recommended due to the high incidence of symptomatic cerebellar tonsillar herniation.
