[Outcome of profile-improving operations in craniofacial abnormalities]

Area of Science:

• Craniofacial Surgery
• Pediatric Plastic Surgery
• Orthodontics

Context:

• Craniosynostosis, a condition involving premature fusion of skull sutures, affects forehead and midface development in children.
• Fronto-orbital advancement is a surgical technique used to correct these deformities.
• Understanding the long-term effects on facial growth is essential for optimizing treatment outcomes.

Purpose:

• To evaluate the impact of fronto-orbital advancement on forehead profile and midface growth in 52 children with craniosynostosis.
• To analyze cephalometric data (SN line, N-Spna line, SNA angle, N-tf line, tf-TF line) to assess growth tendencies post-surgery.
• To determine factors influencing the success of fronto-orbital advancement, including growth disorder type, location, and surgical timing.

Summary:

• The study analyzed 52 children undergoing fronto-orbital advancement for craniosynostosis, with a mean age of 10.5 months and follow-up of 37.2 months.
• Brachycephalic patients showed unfavorable post-operative growth, with inhibited sagittal midface growth (NSA angle) and unaffected vertical midface growth (N-Spna line).
• Forehead profile and size alterations indicated new growth disorders in brachycephalic and some oxycephalic patients, highlighting the complexity of craniofacial development.

Impact:

• The success of fronto-orbital advancement is contingent upon the specific growth disorder, its location, and the patient's age at operation.
• Early surgical intervention is critical for interrupting pathological growth tendencies, even in severe developmental disorders.
• Findings guide surgical timing and technique selection for improved long-term craniofacial outcomes in pediatric craniosynostosis patients.
