摘要
目的：这项回顾性研究的目的是利用正颌功能治疗需求指数（IOFTN）和颌面形态计量分析确定日本颌骨畸形患者的正颌手术指标：受试者包括89名接受正颌外科手术治疗的患者和92名仅接受正畸治疗的患者，根据ANB角度分为I级、II级和III级。根据 IOFTN 分析结果和头颅测量分析结果，研究了正颌外科手术的适应症标准：在 IOFTN 分析中，正颌手术组没有患者被归类为 1 类或 2 类，而正畸治疗组有 48% 的患者被归类为 4 类或 5 类。对第 4 类和第 5 类患者进行头颅测量分析的结果显示，正颌手术组患者的下颌侧偏差在 I 类病例中明显更大，下颌后缩程度在 II 类病例中明显更严重，下颌前突程度在 III 类病例中明显更严重。逻辑回归分析结果表明，IOFTN 是作为正颌手术适应症标准的一个常见变量，而且从每组的头颅测量结果中还选取了几个不同的变量：结论：IOFTN 是一个高度敏感且有用的指标，可作为正颌手术的标准。然而，在选择治疗策略时，颌面形态分析和患者的预期目标也很重要。
Investigation of orthognathic surgery indicators-combination with index of orthognathic functional treatment needs (IOFTN) and maxillofacial morphometric analysis.
Purpose: The aim of this retrospective study was to determine orthognathic surgery indicators for Japanese patients with jaw deformities using both Index of Orthognathic Functional Treatment Needs (IOFTN) and maxillofacial morphometric analysis.
Subjects and methods: The subjects were 89 patients treated with orthognathic surgery and 92 patients treated with orthodontic treatment alone, and were classified as class I, II, or III according to the ANB angle. Based on the results for IOFTN and the results of cephalometric analysis, the indication criteria for orthognathic surgery were examined.
Results: In IOFTN analysis, none of patients in the orthognathic surgery group were classified as category 1 or 2, while 48% of the patients in the orthodontic treatment group were classified as category 4 or 5. The results of the cephalometric analysis of patients in classified categories 4 and 5 showed that the orthognathic surgery group had significantly greater lateral mandibular deviation in Class I cases, significantly more severe degree of mandibular retrusion in Class II cases, and significantly more severe degree of mandibular prognathism in Class III cases. The results of the logistic regression analysis showed that IOFTN was a common variable as an indication criterion for orthognathic surgery, and several different variables were also selected from the cephalometric measurements in each group.
Conclusion: IOFTN is a highly sensitive and useful indicator as a criterion for orthognathic surgery. However, in the choice of treatment strategy, maxillofacial morphometric analyses and the patient's desired goal are important.
期刊介绍：
Oral & Maxillofacial Surgery founded as Mund-, Kiefer- und Gesichtschirurgie is a peer-reviewed online journal. It is designed for clinicians as well as researchers.The quarterly journal offers comprehensive coverage of new techniques, important developments and innovative ideas in oral and maxillofacial surgery and interdisciplinary aspects of cranial, facial and oral diseases and their management. The journal publishes papers of the highest scientific merit and widest possible scope on work in oral and maxillofacial surgery as well as supporting specialties. Practice-oriented articles help improve the methods used in oral and maxillofacial surgery.Every aspect of oral and maxillofacial surgery is fully covered through a range of invited review articles, clinical and research articles, technical notes, abstracts, and case reports. Specific topics are: aesthetic facial surgery, clinical pathology, computer-assisted surgery, congenital and craniofacial deformities, dentoalveolar surgery, head and neck oncology, implant dentistry, oral medicine, orthognathic surgery, reconstructive surgery, skull base surgery, TMJ and trauma.Time-limited reviewing and electronic processing allow to publish articles as fast as possible. Accepted articles are rapidly accessible online.Clinical studies submitted for publication have to include a declaration that they have been approved by an ethical committee according to the World Medical Association Declaration of Helsinki 1964 (last amendment during the 52nd World Medical Association General Assembly, Edinburgh, Scotland, October 2000). Experimental animal studies have to be carried out according to the principles of laboratory animal care (NIH publication No 86-23, revised 1985).
