Rural and urban differences in orthognathic surgical patients in the north east of Scotland

We have previously identified differences in the presentation and treatment of cancer between patients who live in rural compared with urban areas, but have not yet seen differences in those treated by orthognathic surgery. We hypothesised that patients from areas further away from the hospital face higher costs to attend and may not present with minor problems as often as those who live nearby. We therefore retrospectively reviewed all those (n =216) who had presented for orthognathic surgery over a six-year period (May 2011 to May 2017). The severity of malocclusion and facial asymmetry was established by combining measurements of intraoperative movements. Rurality was measured as the distance from home to the hospital at the time of operation. Those with smaller intraoperative movements (less than 7 mm combined movement) lived significantly closer to the hospital as the crow flies (mean difference 15.13 miles, 95% CI 0.20 to 30.48, p=0.05) and could travel there more quickly (mean difference 65 minutes 95% CI 9.8 to 121.7, p=0.02) than those with larger movements. Our results suggest that patients with small malocclusions and slight facial asymmetry who live further away from the hospital, may be less likely to present for operation than those who live closer. We explain why socioeconomic class is unlikely to confound our results, and suggest potential ways to minimise the effect observed.
