Purpose The purpose of this study is to investigate the progression of head circumference following surgical treatment of suture fusion in patients with craniosynostosis. Additionally, we would like to compare the progression of head circumference between the different types of craniosynostosis.
Methods This study is a retrospective review of the progression of head circumference in patients with craniosynostosis following surgical treatment at Children's Hospital Los Angeles (CHLA). Measurements of head circumference taken in clinic pre-operatively and immediately post-operatively within 1 to 2 weeks, at 3 months post-operatively, 6 months post-operatively, and/or 1 year post-operatively are recorded. Head circumference percentiles are compared to the average head circumference of the general population based on the head circumference growth curve.
Results A total of 117 patients were identified to have received surgical treatment of craniosynostosis at CHLA between 1995 and 2005. 66 charts contained appropriate data for collection, including a pre-operative head circumference measurement and post-operative head circumference measurements immediately post-operatively, at approximately 3 months, 6 months, and/or 1 year. Of these, 39 patients had sagittal craniosynostosis, 12 coronal, 4 bicoronal, 3 metopic, 3 lambdoid, and 5 multisynostotic. Preliminary results show a progression of head circumference growth along the growth curve at an age appropriate head circumference percentile following surgical treatment of craniosynostosis. Further investigation is pending.
Conclusion In conclusion, the progression of head circumference following surgical treatment of craniosynostosis is appropriate when compared to a growth curve for head circumference for the general population. Furthermore, the progression of head circumference in patients with coronal synotosis appears to be the more stable when compared to patients with sagittal synostosis, which is more stable than in multisynostotic patients. Head circumference progression in patients with bicoronal, metopic, and lambdoid synostosis also appears more stable than in sagittal synostosis. Further investigation is pending.
