Craniosynostosis and Resynostosis: Models, Imaging, and Dental Implications

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.
