What are the occlusal outcomes for unilateral cleft lip and palate patients? A national project in the UK

Abstract

Aim This national project assessed the orthodontic outcome for unilateral cleft lip and palate (UCLP) patients in the UK.Method Six consecutively treated fixed appliance cases where orthognathic surgery was not undertaken were assessed using the peer assessment rating (PAR) index on orthodontic study models. These cases were submitted by NHS consultant orthodontists undertaking treatment on patients with cleft lip and/or palate.Setting UK NHS consultant-led hospital service.Results The mean reduction in PAR score was 69% ± 22. The mean start PAR score was 41 ± 11. The mean end of treatment PAR was 12 ± 9. The proportion of cases where the score was worse or no different was 7.5%.Conclusion The mean percentage PAR reduction compares well with other national projects looking at outcome from patients treated in the hospital service. The mean PAR reduction could be used as a benchmark for outcome in UCLP orthodontic treatments in future audit projects and the annual consultant appraisal process. © 2007 Nature Publishing Group.
