title: [The effects of endoscopic nasal surgery on the function of eustachian tube].
abstract: OBJECTIVE
  To observe the effects of endoscopic nasal surgery on the function of eustachian tube.
  
  
  METHODS
  The tympanometric pressure, static compliance and gradient of tympanogram were measured for sinuses and turbinate group (10 cases) and nasal septum group (10 cases) at 1, 3, 5 and 10 days after operation by using audiometer acoustic impedance.
  
  
  RESULTS
  The peak pressure of tympanogram of two groups were droped obviously 1-3 days after operation. In sinuses and turbinate group, it droped from -85.5 dapa to -148.0 dapa (at 1 day) and -139.0 dapa at 3 days, compared to the pre-operation, the differences were significantly (P < 0.01). In nasal septum group, it droped from -51.0 dapa to -111.5 dapa at 1 day and -96.0 dapa at 3 days, compared to the pre-operation, the differences were also significantly (P < 0.01). The level of static compliance, gradient were no significantly difference between before and after operation (P > 0.05).
  
  
  CONCLUSIONS
  The eustachian tube of patients of two groups were blocked at the early stage of post-operation. The treatment of active anti-infection, promptly cleaning of nasal cavity, relexing the pressure of nasal cavity as soon as possible, all of this can reduce the effect of operation on the function of eustachian tube.
