[Staging of mucous membrane outcome in operative cavity after functional endoscopic sinus surgery].
OBJECTIVE
To investigate the character of transitionary process of mucosa in sinu cavity after functional endoscopic sinus surgery (FESS) and divide it into different stages.


METHODS
The morphological character of mucosa in sinus cavity after FESS was surveyed continuously.


RESULTS
Over 90% of nasal and sinus cavity got clean within 1 to 2 weeks postoperatively. About 80% of patients had the De-mucous reaction from the 3rd to 10th week, such as mucous edema, vesicles, granulation tissue, mini-polyps, fibrous hyperplasia, and adhesion or regenerated diseases may appear in this stage. All of these diseases competed with mucous epithelization. There were 90% of nasal and sinuous cavity brought to stage of complete epithelization, 11 to 14 weeks were need in about 60% of them.


CONCLUSIONS
Three stages were divided after FESS. They are stage of clean operative cavity, stage of mucous competition and stage of complete epithelization. Proper local care in each stage is essential to the whole curable effect of FESS.
