title: [39 cases of malignant tumors originated from external and middle ear].
abstract: OBJECTIVE
  To describe our experience in the clinical manifestation and treatment of malignant tumors of the external and middle ear.
  
  
  METHODS
  The study reviewed 39 patients between 1994-2011 in our hospital, including 15 pinna tumors, 18 external canal tumors and 6 middle ear tumors. 23 males and 16 females were enrolled in this study. The mean age of patients at the time of surgery was 59. Radiotherapy or radiotherapy and chemotherapy were the only possible treatment in 6 cases. Thirty-three patients were treated surgically, and 9 patients also received radiotherapy after surgery.
  
  
  RESULTS
  All of the patients had been followed up over 3 years, except for 1 case of external canal and 1 case of middle ear tumor. The 3-year survival of pinna, external canal and middle ear tumors were 86.7%, 82.4% and 60.0% respectively. At the last follow up, the pinna tumors showed that the survival rate was 100% in T1, T2 and Tx stage, and 0% in T4 stage; the external canal tumors showed that the survival rate was 90% in T1 stage, and 66.7% in T2, T3 stage; the middle ear tumors showed that the survival rate was 100% in T1 and T2 stage, 0% in T3 stage.
  
  
  CONCLUSIONS
  The T staging system is for an important prognostic factor, and it is important for an early diagnosis and radical surgery to achieve a better therapeutical result.
