Abstract

Purpose

The purpose of our study was to improve the minor asymmetries of fronto-orbital advancement (FOA) by introducing a simple model to guide the FOA in unicoronal synostosis which may help saving time and cost.

Methods

A retrospective analysis of 16 consecutive patients with unicoronal synostosis corrected by FOA guided by a guide model. Patients with syndromic craniosynostosis or associated craniofacial anomalies were excluded from the analysis. In all cases, 3D mirror image models were used for guiding unilateral fronto-orbital advancement. Demographic, perioperative, and follow-up data were collected for comparison. Cranial and orbital volumes were documented preoperatively and postoperatively and compared with the non-synostotic side. The postsurgical appearance of the face was documented photographically and then evaluated and scored using the Whitaker scoring system.

Results

The study included nine males and seven females. The mean age of the patients at the time of the operation was 20.4 months. The mean follow-up duration was 36 months. Mean operative time was 170 min, mean anesthetic time was 230 min, mean blood loss was 50–80 ml, and the average hospital stay was 4.4 days. No relapse that required surgical correction was reported. There were improvements in the orbital indices and volume to be near equal to the normal side. Excellent to good results were obtained in all patients according to the Whitaker classification system.

Conclusion

Residual deformity after FOA mandates another tool to optimize the results. Our study introduced a simple, easy, and applicable method to guide the FOA with lesser asymmetries.
