title: [Clinical analysis of 19 cases of esthesioneuroblastoma under classic surgical approaches and surgical approaches with the assistant of nose endoscope].
abstract: OBJECTIVE
  To summarize the curative effect and esthesioneuroblastoma (ENB) by classic surgical approaches and surgical approaches with the assistant of nose endoscope.
  
  
  METHODS
  A retrospective review was conducted in 19 cases treated from 1980 to 2000. Ten cases were treated by classical surgical approaches. Tumors in 4 patients (According to the Kadish system, stage A, 3 cases; stage B, 1 case) were removed via a transnasal approach, 6 patients (stage B, 5 cases; stage C, 1 case) were performed by lateral rhinotomy. After 1995, 9 cases (stageA, 2 case; stageB, 5 cases; stageC, 2 cases) received surgical resection with nasale endoscope. All of the patients were conducted radiation after operation.
  
  
  RESULTS
  The 5-year survival rate for the classic procedure and the surgical procedure with the assistant of endoscope were 50.0%, 88.9%, respectively. And the local recurrence rates were 50.0%, 33.3%, respectively (had no statistical significance). And the mean recurrent time were 5.2 months, 16 months, respectively. With the assistant of endoscope, the recurrent time was significant retarded.
  
  
  CONCLUSIONS
  There are better illumination and better operation field during the surgical operation with the assistant of endoscope. And the tumors are more likely resected entirely and the tumor recurrent time could be deferred.
