title: [Preliminary approach of deep and superficial layer under intranasal endoscope operation for nasal septum malignant tumour].
abstract: OBJECTIVE
  To preliminary discuss the questions of deep and superficial layer under intranasal endoscope operation for nasal septum malignant tumour.
  
  
  METHODS
  The patients of 19 cases with nasal septum malignant tumour who adapt to the operation under intranasal endoscope were divided into 3 groups and were treated separately according to the range, position, infiltrative degree of tumour and exploring conditions in operative process. The treatments of first group had executed with first layer operation. The second group had executed with second layer operation in addition partial patients radiotherapy. The third group had executed with third layer operation in addition total patients radiotherapy.
  
  
  RESULTS
  The tumour-free survivals have 4 cases and local recurrences have 2 cases in 6 cases of first group. The tumour-free survivals have 5 cases, local recurrence has 2 cases, local metastasis has 1 cases and death has 1 case in 9 cases of second group. The tumour-free survivals have 2 cases, local recurrence has 1 case and local metastasis has 1 case in 4 cases of third group. The treated effects have not statistical differences in 3 groups (P > 0.05). Five-year survival rate was 84.2% and five-year tumour-free survival rate was 57.9% for all patients.
  
  
  CONCLUSIONS
  The operations under intranasal endoscope for nasal septum malignant tumour have certainly indication. The selection of operative deep and superficial layer and control of operative safety margin have the same important clinical signification.
