title: [Experimental and clinic study of the maxillary sinus plasty following Caldwell-Luc].
abstract: OBJECTIVE
  To investigate the clinical effect of surgical procedures on patients with chronic maxillary sinus disease.
  
  
  METHODS
  On the basis of experimental study with animal, this prospective study included 63 patients with chronic maxillary sinus disease who had a maxillary sinus plasty following Caldwell-Luc. The operation procedures included anterior wall ring-drilling, and middle meatal antrostomy as well as sinus wall plasty.
  
  
  RESULTS
  Experimental results showed that the repair and regeneration of maxillary sinus mucosa was intact in dogs after 5 weeks of radical operation. Clinical study indicated that the condition of anterior wall with a resutured bone-lid was normalized radiographically during the follow up time of 1-3 months. The patency rate of the middle meateal antrostomy 18-42 months post-operatively (average 28 months) is 96%.
  
  
  CONCLUSIONS
  We conclude from the study that the maxillary sinus plasty recovers anatomic construction, maintains physiological drainage way and provides a good environment for repair and regeneration of the sinus mucosa.
