title: Patient- and clinician-perceived need for orthognathic surgery.
abstract: BACKGROUND
  To better understand why patients believe they need orthognathic treatment, a study was undertaken to examine perceived need for treatment by patients and clinicians. This questionnaire-based study was undertaken at The John Radcliffe Hospital, Oxford, United Kingdom.
  
  
  METHODS
  Forty patients were recruited from combined orthodontic-surgical clinics. They were asked to rate their perceived need for treatment based on facial appearance, dental appearance, function, and overall need. Twenty orthodontists and 20 maxillofacial surgeons were asked to rate perceived need for treatment based on the same parameters, using study models and clinical photographs. Ratings were marked on visual analog scales.
  
  
  RESULTS
  Significant differences were found between patients and clinicians in perceived need for treatment based on facial appearance (orthodontists compared with patients, P = .023; surgeons compared with patients, P = .001). In addition, maxillofacial surgeons rated a significantly greater overall need for treatment than patients (P = .027), and they rated treatment need based on facial appearance (P = .005) and function (P < .001) significantly higher than orthodontists.
  
  
  CONCLUSIONS
  Clinicians rated greater need for orthognathic treatment based on facial appearance than did patients. Surgeons also rated greater overall need for treatment than patients. In addition, surgeons rated treatment need based on facial appearance and function significantly higher than orthodontists, but large variations existed in both clinician groups.
