title: [Treatment and effective analysis on maxillary complex injury].
abstract: OBJECTIVE
  To analyze the characteristics of cases of maxillary complex injury, to sum up experiences and lessons in the clinical first aid process, to evaluate different treatment effects of maxillary complex fracture and investigate the reasons for the failure of the treatment process.
  
  
  METHODS
  152 cases with maxillary complex injury were analyzed retrospectively.
  
  
  RESULTS
  2 cases (1.32%) died during emergency treatment. The cure rate was 62.67% (94/ 150) in the 150 survival cases. The cure rate of closed fractures were better than open ones and surgical treatments than non-surgical ways (P < 0.05); the cure rate of surgical treatment in stage I was higher than II (P < 0.01).
  
  
  CONCLUSIONS
  For patients with complex injuries of maxillary, first aid failure is mainly due to bleeding or asphyxiation. Therapeutic efficacy is influenced by treatment time, surgical approach, type of treatment and so on. The key to success of treatment is dependent on the early firm internal fixation and the functional protection and restoration of injured organs or tissues.
