Abstract

Objectives: The pupose of the study was to visualize the integrity of the sinus membrane by endoscope during sinus lifting via magic sinus lifter.
Methods: Twelve patients with atrophic distal edentulous maxillary region with bone height ranged from 3-5 mm.These patients were selected to perform crestal sinus lifting under endoscopic monitoring with a newly designed sinus lifter (magic sinus lifter). The endoscope was used to visualize the membrane elevation during lifting procedures and implant insertion.
Results: Ten cases showed succefull membrane elevation without any tear. Two cases monitored with membrane perforation. One was visualized when the endoscope entered through the crestal osteotomy site, while the other membrane perforation visualized from lateral sinus wall. There was a correlation of the perforated membrane with its morphology as it was irregular shape and thin in thickness. The magic sinus lifter showed marvelous bone cutting and elevation without any heat generation.
Conclusion: Endoscopic visualization of sinus membrane during elevation is an accurate method for membrane assessment. The magic sinus lifter can penetrate the posterior crestal bone to elevate the sinus membrane with gentle malleting. The use of endoscope should be recommended in thin membranes when endoscopy equipment& training is available.
