To retrospectively assess malocclusions, skeletal relationships and the functional needs of orthognathic patients treated in a University teaching hospital.
This study used clinical records of 100 consecutive patients [51 female, 49 males, mean (SD) age =21.5 (2.71) years] who had orthognathic surgery in a Shahid Beheshti University of Medical Sciences affiliated hospital (9/2014-7/2017). Malocclusion type (incisor classification), sagittal skeletal pattern (ANB angle), index of orthognathic functional treatment need (IOFTN) score, and osteotomy type were recorded.
Overall, 66%, 31%, and 3% had Class III, II, and Class I malocclusions, respectively. Similarly, 68% and 32% had Class III and II sagittal skeletal relationships, respectively. Overall, 95% of patients scored IOFTN 4 or 5. The most prevalent IOFTN score were 4.3 (37%), 5.3 (16%), 5.4 (16%), and 4.2 (10%). There were no gender differences (P >0.05) for the distribution of malocclusions, sagittal skeletal relationships, different IOFTN scores, or when IOFTN scores were re-grouped (5, 4, and ≤3). When IOFTN scores were re-grouped (5, 4, and ≤3), they were equally distributed among patients with Class II or III skeletal relationships (P >0.05), but when the authors looked at different malocclusions, there were significant differences in IOFTN score distribution (P = 0.006). The use of genioplasty (4%) or distraction osteogenesis (2%) was limited. Single jaw surgery of either maxilla or mandible was used in 15% and 22% of patients, respectively. About 63% had undergone double-jaw surgery.
Retrospective assessment using IOFTN identified 95% of patients as having great and very great functional needs, but prospective studies using IOFTN is needed to assess the need for orthognathic surgery. Class III malocclusions and Class III sagittal skeletal relationships were more common in this sample.
回顾性评估在一所大学教学医院接受正颌治疗的患者的错颌畸形、骨骼关系及功能需求。
本研究采用了100例连续患者的临床记录[51例女性，49例男性，平均（标准差）年龄=21.5（2.71）岁]，这些患者于2014年9月至2017年7月在沙希德·贝赫什提医科大学附属医院接受了正颌手术。记录错颌类型（切牙分类）、矢状面骨骼类型（ANB角）、正颌功能治疗需求指数（IOFTN）评分及截骨类型。
总体而言，分别有66%、31%和3%的患者为III类、II类和I类错颌畸形。同样，分别有68%和32%的患者为III类和II类矢状面骨骼关系。总体而言，95%的患者IOFTN评分为4或5。最常见的IOFTN评分为4.3（37%）、5.3（16%）、5.4（16%）和4.2（10%）。错颌畸形、矢状面骨骼关系、不同IOFTN评分的分布，或IOFTN评分重新分组为（5、4和≤3）时，均无性别差异（P>0.05）。当IOFTN评分重新分组为（5、4和≤3）时，其在II类或III类骨骼关系患者中分布均匀（P>0.05），但当作者观察不同错颌畸形时，IOFTN评分分布存在显著差异（P=0.006）。颏成形术（4%）或牵张成骨术（2%）的应用有限。分别有15%和22%的患者采用了上颌或下颌单颌手术。约63%的患者接受了双颌手术。
使用IOFTN进行回顾性评估发现95%的患者有很大和非常大的功能需求，但需要使用IOFTN进行前瞻性研究以评估正颌手术的需求。本样本中III类错颌畸形和III类矢状面骨骼关系更为常见。
