title: [Variations of the middle meatus mucosa ultrastructure after endoscopic sinus surgery].
abstract: OBJECTIVE
  To explore the variations of middle meatus ultrastructure after endoscopic sinus surgery.
  
  
  METHODS
  10 cases whose middle meatus mucosa recovered well after undergoing endoscopic sinus surgery were screened, and postoperative electron microscope examinations of middle meatus mucosa were made in the first, second, third and forth month.
  
  
  RESULTS
  In the first month after operation, there was obvious fibre proliferation in the mucosa. In the second month, there was fibre proliferation and dissolution existing simultaneously. In the third month, the mucosa's structure resumed fundamentally to normal, but its function was not perfect. In the forth month, the mucosa was completely normal and can function normally.
  
  
  CONCLUSIONS
  The mucosa of middle meatus can resume completely after endoscopic sinus surgery but need at least four months. It is very important to have a long time reexamination for improving therapeutic effect.
