title: [Clinical analysis of radionuclide bone scan in patients with facial asymmetry].
abstract: OBJECTIVE
  To study the radionuclide distribution in mandible of patients with facial asymmetry and help to select proper time and type of treatment.
  
  
  METHODS
  The control group included 29 people with no facial asymmetry, while the experimental group consist of 207 patients with facial asymmetry. The radioactive count in 29 normal controls and 207 patients with facial asymmetry were measured and compared using 99mTc-MDP intake percentage in mandibular condyle, ramus and body. SPSS13.0 software package was used for statistical analysis.
  
  
  RESULTS
  There was significant difference between adult and adolescent patients in 99mTc-MDP intake of the condyles. There was no significant difference between male and female in the 99mTc-MDP intake of the condyles. The 99mTc-MDP intake difference percentage was (22.50±1.67)%, (6.93±1.02)% and (13.67±0.95)% in mandibular condyle, ramus and body, respectively. The intake difference value of the condyle was the biggest.
  
  
  CONCLUSIONS
  The mandible growth trend is different from the body's growth and development trend. We can analyze the trend of mandible development by radionuclide bone scan and select proper time and type of treatment.
