Abstract
ObjectiveThe aim of this retrospective review was to assess the usage of the IOFTN in a South East Asian craniofacial deformity center setting with regards to patients having dentofacial deformity indicated for orthognathic surgery. MethodsA retrospective study was carried out on patients who had undergone orthognathic surgery at Selayang hospital from January 2011 to February of 2017. Variables measured included skeletal sagittal relationship, malocclusion classification, type of osteotomy, IOTN score and IOFTN score. Results84 patients with a mean age of 21.38 was included in the study. The most prevalent IOFTN score in our sample was 5.3 (33.3%) followed by 4.3 (13.1%). 33.4% of patients were classified as having a great need for treatment and 57.1% a very great need for treatment. 9.5% of patients have a moderate need for treatment. No patients were graded below 3. ConclusionThe IOFTN is a reliable tool and a more accurate indicator of treatment need for patients with dentofacial deformity requiring orrthognathic surgery compared to the IOTN.
