To assess the functional needs of orthognathic cases treated in Northampton General Hospital using the index of orthognathic functional treatment need (IOFTN).
A retrospective study was conducted on 78 subjects (54 female and 24 males, 10-54 years, mean (SD) age=21.88 (6.98) years) who had orthognatic surgery in Northampton General Hospital or were in preparation for it (5 case). The sample represents a period between February 1997 and December 2014. The components of IOFTN and Dental Health Component (DHC) of the Index of Orthodontic Treatment Need (IOTN) as well as Malocclusion type were recorded.
Class III malocclusion/skeletal pattern was the most prevalent type (approximately 49%). There were 1, 36, 3, and 38 subjects with Class I, Class II Division I, Class II Division II, and Class III malocclusions, respectively. In terms of sagittal skeletal relationship, there were 2, 37, and 39 subjects with Class I, Class II, and Class III skeletal bases, respectively. The most prevalent IOFTN score in our sample was the 5.2 (29.5%), followed by 5.3 (15.5%), 4.2 (13%), 4.3 (11.5%). Overall, 92.3% were classified as in great and very great functional needs according to the IOFTN. Similarly, 84.6% scored as grade 4 or 5, according to the IOTN (DHC). The bimaxillary type osteotomy was the most prevalent type (61.5%).
Using IOFTN, 92.3% of our sample were classified as having great and very great functional needs. IOFTN is a simple and reliable tool to identify patients in need of orthognathic surgery and can be used in resource allocation for patients with highest functional needs.
使用正颌功能治疗需求指数（IOFTN）评估在北安普敦综合医院接受治疗的正颌病例的功能需求。
对78名受试者（54名女性和24名男性，年龄10 - 54岁，平均（标准差）年龄 = 21.88（6.98）岁）进行回顾性研究，这些受试者在北安普敦综合医院接受了正颌手术或正在准备手术（5例）。样本涵盖1997年2月至2014年12月期间。记录了IOFTN的组成部分、正畸治疗需求指数（IOTN）的口腔健康组成部分（DHC）以及错颌类型。
III类错颌/骨骼型是最常见的类型（约49%）。分别有1名、36名、3名和38名受试者为I类、II类1分类、II类2分类和III类错颌。在矢状面骨骼关系方面，分别有2名、37名和39名受试者为I类、II类和III类骨骼基底。我们样本中最常见的IOFTN分数是5.2（29.5%），其次是5.3（15.5%）、4.2（13%）、4.3（11.5%）。总体而言，根据IOFTN，92.3%被归类为有很大和非常大的功能需求。同样，根据IOTN（DHC），84.6%的受试者评分为4级或5级。双颌截骨术是最常见的类型（61.5%）。
使用IOFTN，我们样本中的92.3%被归类为有很大和非常大的功能需求。IOFTN是一种简单可靠的工具，可用于识别需要正颌手术的患者，并可用于为功能需求最高的患者进行资源分配。
