One-piece fronto-orbital distraction osteogenesis without bandeau in patients with coronal craniosynostosis: A five-year follow-up retrospective study of 45 consecutive patients

초록

This study aimed to review the surgical outcomes, complications, and long-term relapses in patients with unilateral or bilateral coronal craniosynostosis, who underwent one-piece fronto-orbital distraction osteogenesis (FODO) without bandeau. The cephalic index, frontal angle, and supraorbital symmetry ratio were measured on the initial and follow-up computed tomography images. Esthetic outcomes were evaluated using the Whitaker classification. 45 patients were included in this study. The average follow-up interval was 5.4 ± 1.1 years (range 2.5–8.5 years). In patients with bilateral coronal craniosynostosis, the frontal angle decreased with a relapse ratio of −2.8 ± 4.3% during long-term follow-up compared with that during short-term follow-up (p = 0.028). In patients with unilateral coronal craniosynostosis, the supraorbital symmetry ratio decreased slightly, with a relapse ratio of −3.8 ± 2.6% during long-term follow-up (p = 0.017). Complications included dural tears during osteotomy (n = 2), early distractor removal (n = 2), and wound problems (n = 3). Within the limitations of the study it seems that one-piece fronto-orbital distraction osteogenesis (FODO) generates successful and sustainable results even in the long term. Therefore, this treatment option should be considered for patients with unilateral and bilateral coronal craniosynostoses whenever appropriate.
