A secondary aim was to assess the IOFTN in the orthognathic cohort and to investigate any correlation between the functional domain of OQLQ and IOFTN. Materials and Methods: Orthognathic patients prior to commencing pre-surgical orthodontics from five regional HSE orthodontic units within the RoI and randomly selected age-matched subjects from the general population were invited to complete a telephone interview. Participants were asked questions regarding general characteristics and then asked to respond to the validated questionnaires OHIP-14, OQLQ, and BFNES. IOFTN grades of the orthognathic sample were also assessed. Results: Eighty orthognathic patients (39 males; 41 females) with an overall mean age of 17.5 (SD 1.6) years and 213 subjects from the general population (95 males; 118 females) with an overall mean age of 17.8 (SD 1.5) years completed a telephone interview. Orthognathic patients had significantly higher mean scores for OHIP-14, OQLQ and S-BFNES than the general population (p < 0.001). The mean score of OHIP-14 for the orthognathic patients and the general population were 14 (SD 8.6) and 5 (SD 5.9) respectively. Corresponding group scores for OQLQ were 40.9 (SD 19.3) and 19.9 (SD 14.9), and for S-BFNES were 23.2 (SD 7.2) and 18.8 (SD 8.1). Females had higher overall OQLQ and S-BFNES scores than males in both groups (p < 0.0001). There was no significant difference in the distribution of self-reported BMI categories between the groups (p = 0.8931). More than 90 per cent of the orthognathic sample were in IOFTN grade 4 and grade 5 showing ‘great’ and ‘very great’ functional need for surgery respectively. No association was found between the functional domain of OQLQ and IOFTN categories (p=0.5530). Conclusion: Orthognathic patients reported significantly poorer oral-health related and condition-specific quality of life as well as higher levels of social anxiety than the general population. Females in both groups had higher scores than males for OQLQ and S-BFNES. There was no correlation between the functional domain of OQLQ and IOFTN.
