Quantitative Assessment of Supraorbital Osseous Bar Stability and Symmetry after Frontal Orbital Advancement for Unilateral Coronal Craniosynostosis
Frontal-orbital advancement is the treatment for correcting the cranial deformity associated withpremature fusion of one of the coronal cranial sutures. Removaland reshaping of the brow and lower forehead bone is performedto correct ipsilateral frontal flattening and parietal bulging,recession of the supraorbital rim, and contralateral foreheadbossing. In addition to the functional aspects of the treatment,bilateral symmetry is one desirable outcome that is difficult toachieve because of the recessive movement and shape changes of the supraorbital rim that continue to occur over a prolongedperiod of time after the operation. Surgeons often over correctthe deformity to compensate for post-operative recession andachieve better symmetry at skeletal maturity. This study is toquantitatively evaluate the stability and symmetry of the repairedsupraorbital rim after the craniofacial reshaping procedures inpatients with unilateral fusion of the coronal suture. CT scanstaken at pre-op, post-op and two years later were available fordigital analysis. Quantitative methods are developed to calculatethe magnitude of advancement, magnitude of movement in the two years period following the surgery, and supraorbital bilateralsymmetry at all three time points. Quantitative statistics of thepost-op supraorbital rim stability will provide clinically relevantinformation for surgical planning that could optimize surgicaltechnique.
