title: [Demonstration of the maxillary mucosa restoration after operation to the nasal fungal sinusitis].
abstract: OBJECTIVE
  This paper aims to demonstrate the maxillary mucosa restoration after operation to the nasal fungal sinusitis.
  
  
  METHODS
  Observation by microscopic, transmission electron microscopic and scanning electron microscopic was done to the same parts in the maxillary mucosa 3-4 months before and after the endoscopic sinus surgery in the 24 cases of the nasal fungal sinusitis during 2003-2005.
  
  
  RESULTS
  Before the operation, all the cases demonstrated epithelia shedding, proliferation, squamous metaplasia, glandular and fibrous tissue proliferation and lymphocytes infiltration. The microtubule was abnormal and mitochondria diminished, 3-4 months after operation, the cavity was clear and smooth and the epithelia complete. The cilia average increased and the cilia lined in the same direction. The structure of microtubules was clear. The mitochondria was elongated and dense.
  
  
  CONCLUSIONS
  There was no significant difference in the damage on ultramicrostructure of the maxillary mucosa between the chronic nasal sinusitis and chronic nasal fungal sinusitis. It is crucial in the successful recovery that the operation gives a thorough clean to the fungal clot and sinus aeration, and that good cleaning and sinus aeration are maintained after the operation. The ultramicrostructure restoration and the function recovery of mucosa will be achieved after careful cleaning for 3-4 months after operation.
