: The present study aims to compare the accuracy of jaw repositioning in bimaxillary orthognathic surgery using digital surgical planning in cleft lip and palate patients and in non-syndromic skeletal class III patients in order to investigate if orthognathic surgery achieves different results in the first group of patients. : This study included 32 class III adult patients divided into 2 groups: cleft lip and palate (A, = 16) and non-cleft (B, = 16). For each patient, a 2D pre-surgical visual treatment objective was performed by the surgeon to predict hard tissue changes, and the surgical outcome was compared with that planned by using cephalometric measurement (ANB, SNA, SNB, Ar-Go-Me, S-Ar-Go). The statistical analysis showed equivalence between obtained and planned results for each measurement both in group A and in group B, but the difference between the planned and the obtained result was smaller in group B regarding ANB angle. : Digital surgical planning ensures better predictability of the surgical results and higher accuracy of surgery in complex patients, such as those with cleft lip and palate.
本研究旨在比较唇腭裂患者和非综合征性骨性III类患者在双颌正颌手术中使用数字化手术规划进行颌骨重新定位的准确性，以调查正颌手术在第一组患者中是否会取得不同的结果。本研究纳入了32例III类成年患者，分为2组：唇腭裂组（A组，n = 16）和非唇腭裂组（B组，n = 16）。对于每位患者，外科医生进行二维术前视觉治疗目标以预测硬组织变化，并使用头影测量法（ANB、SNA、SNB、Ar-Go-Me、S-Ar-Go）将手术结果与计划结果进行比较。统计分析表明，A组和B组各项测量的获得结果与计划结果之间具有等效性，但就ANB角而言，B组计划结果与获得结果之间的差异较小。数字化手术规划可确保在复杂患者（如唇腭裂患者）中手术结果具有更好的可预测性和更高的手术准确性。
