title: [Effect of nasal cavity expansion surgery on chronic nasal obstructive diseases on the blood supply of the cerebral arterial system].
abstract: OBJECTIVE
  To investigate the effect of nasal cavity expansion surgery on the abnormal blood supply of the cerebral arterial system.
  
  
  METHODS
  Fifty-nine inpatients with abnormal blood supply of cerebral arterial system confirmed by transcranial doppler (TCD) and chronic nasal obstructive diseases were included in this study. All patients accepted nasal cavity expansion surgery and were followed-up with TCD every month after operation until TCD became normal, or up to seven months even if the TCD was still abnormal. SPSS 17.0 software was used to analyze the data.
  
  
  RESULTS
  In all 59 patients, there were 164 TCD-abnormal cerebral arteries. Among them, 37 patients(62.71%) with abnormal TCD arteries became normal within 1 to 7 months after operation, 8 patients (13.56 %) got better, but 14 patients (23.73 %) did not improve.
  
  
  CONCLUSIONS
  Abnormal blood flow of some cerebral arteries was possibly induced by increasing the activation of sympathetic nervous system around the vertebral arterial system, caused by chronic nasal obstruction. Nasal dilatancy surgery can improve the blood supplement of the cerebral arterial system.
