title: Fibrous dysplasia in the jaws of a Hong-Kong population: radiographic presentation and systematic review.
abstract: OBJECTIVE
  To compare the radiographic presentation of fibrous dysplasia in the jaws of Hong Kong patients with the features reported in other populations.
  
  
  METHODS
  The clinical records and radiographs were reviewed of seven patients with fibrous dysplasia whose diagnosis had been histopathologically confirmed. Published series of fibrous dysplasia were subjected to systematic review.
  
  
  RESULTS
  The male:female ratio was 4:3: one woman was Indian in origin; the other six patients were ethnic Chinese. The females were on average older than the males. Three cases affected the mandible and four the maxilla. Five cases affected the right side and two the left. A swelling was the principle clinical manifestation. The lesions were generally large, affecting most or all of the hemimandible or hemimaxilla involved. All cases exhibited expansion and had ground glass opacification. The four cases affecting the maxilla reduced the lumen of the maxillary antrum. The systematic review was carried out on 104 individual cases derived from nine reports of which only 93 cases were accompanied by radiological details. Many of the reports were limited in their scope, particularly with regards to radiological features. Fibrous dysplasia is more frequent in the maxilla in Oriental populations. Swelling is the most frequent clinical finding and buccolinqual expansion the most frequent radiological finding.
  
  
  CONCLUSIONS
  The pattern of presentation of fibrous dysplasia in a Hong Kong population is broadly in agreement with reports from other populations.
