Insights
Craniosynostosis, premature skull fusion in infants, can lead to complications. Surgical repair may require further intervention due to bone regrowth, known as resynostosis.
Area of Science:
- Pediatric Surgery
- Craniofacial Surgery
- Developmental Biology
Background:
- Craniosynostosis affects 1 in 2,000 children, resulting from premature fusion of cranial sutures.
- Untreated craniosynostosis can cause increased intracranial pressure and cranial deformities.
- While over 100 mutations cause syndromic craniosynostosis, most cases are nonsyndromic.
Purpose of the Study:
- To review dental and maxillofacial implications of craniosynostosis.
- To discuss clinically relevant animal models for craniosynostosis and resynostosis.
- To provide information on imaging modalities for cranial defects.
Main Methods:
- Literature review of craniosynostosis research.
- Analysis of animal models for craniofacial development and repair.
- Overview of imaging techniques in human and animal studies.
Main Results:
- Complex cranial vault reconstruction is often required, carrying significant morbidity risks.
- Resynostosis (bone regrowth) occurs in up to 40% of patients after initial surgery.
- Resynostosis frequently necessitates additional surgeries with potential for severe complications.
Conclusions:
- Craniosynostosis presents significant surgical challenges, including high rates of resynostosis.
- Understanding animal models and imaging is crucial for advancing treatment strategies.
- Further research into preventing resynostosis is critical for improving patient outcomes.
Abstract:
Craniosynostosis occurs in approximately 1 in 2,000 children and results from the premature fusion of ≥1 cranial sutures. If left untreated, craniosynostosis can cause numerous complications as related to an increase in intracranial pressure or as a direct result from cranial deformities, or both. More than 100 known mutations may cause syndromic craniosynostosis, but the majority of cases are nonsyndromic, occurring as isolated defects. Most cases of craniosynostosis require complex cranial vault reconstruction that is associated with a high risk of morbidity. While the first operation typically has few complications, bone rapidly regrows in up to 40% of children who undergo it. This resynostosis typically requires additional surgical intervention, which can be associated with a high incidence of life-threatening complications. This article reviews work related to the dental and maxillofacial implications of craniosynostosis and discusses clinically relevant animal models related to craniosynostosis and resynostosis. In addition, information is provided on the imaging modalities used to study cranial defects in animals and humans.
