[Experimental and clinic study of the maxillary sinus plasty following Caldwell-Luc]
Objective:
To investigate the clinical effect of surgical procedures on patients with chronic maxillary sinus disease.
Method:
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.
Result:
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%.
Conclusion:
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.
