Supraorbital ridge protrusion is an unpleasant facial characteristic in China. Literature describing the surgical correction of supraorbital ridge protrusion is scarce.This study aimed to present a surgical technique for correcting supraorbital ridge protrusions.The anterior wall of the frontal sinus and the outer cortex of the frontal bone were removed to form a frontal bone flap, which was regrafted after being trimmed to suitable shape and size. Microabsorbable or titanium plates and screws were fixed on the bilateral side of the bone flap. Anteroposterior depth (the distance between the anterior and posterior wall of the frontal sinus, A-PD), nasofrontal angle, and forehead inclination were measured on the middle sagittal plane before and after corrective operation.All patients got satisfactory appearances in this study. All the variations of measurements showed that the excessive prominent supraorbital ridge had been improved significantly. The result of the Wilcoxon signed-rank test showed that the P value for A-PD was 0.043, which indicated that there were significant statistical differences between preoperative and postoperative A-PD in the midsagittal plane. No recurrence or complications were found during 1 year of follow-up.The fronto-orbital reshaping osteotomy is a reliable technique for correcting supraorbital ridge protrusions. Major complications were not observed and satisfying appearances were obtained.
