“…Similar to the other studies, a high percentage (94%) of this sample were scored as having great and very great functional needs [16,17,18,19,28], and most of the patients with Class III skeletal relationships were classified as grade 5 [16,17,18,19]. This study also revealed that most of the subjects with high-angle skeletal relationships (60%) were categorized as IOFTN grade 5 or 4.…”

“…Different from previous indices, the IOFTN also considers the presence of sleep apnea (score 5.6). Similar to other studies, there were no patients who underwent orthognathic surgery merely because of sleep apnea [17,18,19]. In the case of sleep apnea, genioplasty is sometimes applied for functional purposes.…”

“…IOFTN is a newly developed index, and a limited number of studies have been published on IOFTN so far [14,15,16,17,18,19]. Harrington et al [19] conducted a retrospective study using the data of Northampton General Hospital in the UK and reported that the most prevalent IOFTN score was 5.2 (increased overjet > 9 mm), followed by 5.3 (reverse overjet ≥ 3 mm), and 4.2 (increased overjet ≥ 6 mm and ≤ 9 mm).…”

“…This was mainly to correct the maxillary transverse deficiency prior to orthognathic surgery. Reviewing previous studies it is not clear if they included cases with distraction osteogenesis as a part of dentofacial deformity correction [14,18,32].…”

Objectives: Limited information exists on orthognathic procedures and respective dentofacial deformities in Turkey. This retrospective study assessed the orthognathic surgery procedures in two universities, using the Index of Orthognathic Functional Treatment Need (IOFTN), and compared the IOFTN grades according to gender as well as sagittal and vertical skeletal relationships. Material and Methods: Records of 200 consecutive patients (120 females, 80 males, mean age = 23.4 (SD: 5.4) years) who received orthognathic treatment (2014–2018) were analyzed. Sagittal (ANB angle) and vertical skeletal type (GoGnSN angle), osteotomies, and IOFTN scores were recorded. Results: Class III, II, and I malocclusions formed 69%, 17.5%, and 13.5% of the samples, respectively. Class III skeletal relationships (69%) and high-angle cases (64%) were the most prevalent (p < 0.05). IOFTN scores were unevenly distributed among genders (p < 0.05) and the prevalent scores were 5.3 (40.5%), 4.3 (15.5%), 5.4 (13%), and 5.2 (7.5%), with 94% scoring 4 or 5 (great and very great functional need). Bimaxillary osteotomies were the most prevalent (55%), followed by LeFort I (32%), and 26% had genioplasty. Conclusion: IOFTN is a reliable tool to identify patients in need of orthognathic surgery. Class III malocclusions and Class III sagittal skeletal relationships were more common in this sample. Comparatively, a higher number of patients had genioplasty as a part of their treatment.

Objectives: To retrospectively assess malocclusions, skeletal relationships and the functional needs of orthognathic patients treated in a University teaching hospital. Subjects and methods: 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. Results: 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. Conclusion: 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.

Index of Orthognathic Functional Treatment Need (IOFTN) Identifies patients with greatest need for orthoganthic surgery. This systematic review looks into the available evidence on prevalence of patients with great treatment need (IOFTN 4&5) who had orthognathic surgery in previous studies. Literature search of the major electronic databases was carried out for articles published between 2014 and September 2023, looking for “Index of Orthognathic Functional Treatment Need”,“Orthognathic Surgery”,“IOFTN”, “Epidemiology” and “Dentofacial Deformity”. The prevalence of patients identified with IOFTN grades of 4&5 was calculated. A random-effect model was employed and the Forest and Galbraith plots were produced. The pooled prevalence estimate for subjects with IOFTN scores of 4&5 was calculated. The heterogeneity among studies was assessed with the I2 statistics. In total, 14 retrospective studies conducted between 2015 and 2019 in 7 countries (UK, New Zealand, Iran, Pakistan, Turkey, Malaysia, Japan) were included, reporting on 1339 orthognathic patients. The sample sizes ranged from 30 to 200. Only 7 studies reported on the subcategories of the IOFTN for grades 1, 2&3. The prevalence of orthognathic patients with IOFTN scores of 4 & 5 ranged from 79% to 100%. The heterogeneity I2 statistics was 16%. The pooled prevalence estimate for subjects with IOFTN scores of 4&5 was 92% (95% CI, 0.91-0.94%). According to this meta-analysis, IOFTN successfully identified 92% of patients who underwent orthognathic surgery with a great need for treatment (Grade 4 & 5). To enhance the identification of patients with well-compensated malocclusions, previous orthodontic treatment, or extreme occlusal deviations (e.g., proclination or retroclination of incisors), it would be advantageous to employ additional means alongside IOFTN for assessing orthognathic need in this group.
