title: [The influence of implantal autograft bone in total cleft palate on maxillary growth an experiment study in dogs].
abstract: OBJECTIVE
  To test the hypothesis that implant autograft bone in total cleft palate at primary cleft palate repair which may resists the disturbance of maxillary growth by cleft and denud bony wound.
  
  
  METHODS
  40 dogs were randomly divided into four groups: three control groups and one experimental group. The first control group was unoperated, the second group had a surgically created cleft plate, the third group also had a surgically created cleft palate. Using a two-flap procedure immidiately, the experiment group had a surgically created cleft palate, but the palate was recontracted by implanting a piece of autograft rib bone with two-flap repair. All animals were sacrificed on the 34th week after operation (43 weeks postnatal). Thirty-four metricranial variables were measured directy from the cleaned skulls.
  
  
  RESULTS
  The method is useful for maxillary growth and development by bone implant in total cleft palate, but it can cause maxillary deformity.
  
  
  CONCLUSIONS
  Clinical doctors should be cautious in using the method of primary-delay bone grafting in reparing total cleft of cleft palate.
