title: [EGG used in laryngeal diseases].
abstract: OBJECTIVE
  To analyze the EGG of laryngeal diseases and to evaluate the significance of Electroglottgrapihc waveform in the diagnosis of laryngeal diseases.
  
  
  METHODS
  The computer multimedia program of Dr. Speech science for Windows was used to obtain the EGG parameters in 120 cases of vocal polyp, 42 cases of vocal nodule, 21 cases of vocal cord paralysis, 42 cases of laryngeal cancer and 38 cases of Reinke's edema. The ECG parameters were analyzed.
  
  
  RESULTS
  The special abnormal changes in the waves of EGG were related to the formation (type, position and size ) of laryngeal disease.
  
  
  CONCLUSIONS
  The changes of Electroglottgraphic waveform perform a quantitative and objective index to the diagnosis of the laryngeal disease.
