title: Maxillary sinus lift performed using ultrasound. Evaluation of 21 patients.
abstract: OBJECTIVE
  The aim of the present study was to evaluate the sinus membrane perforations that occurred during a sinus lift procedure using the ultrasound technique, and to evaluate the bone gain obtained.
  
  
  METHODS
  In 21 patients, 26 sinus lifts were performed using ultrasound and filled with bone graft material. The bone height and the bone gain obtained were observed in postoperative orthopantomographs, correcting for previous distortion.
  
  
  RESULTS
  Of the 26 maxillary sinus lifts, 4 Schneiderian membrane perforations were observed. The average bone height prior to the intervention was 3.5 mm (scale 0.6- 8.7 mm ) and the average postsurgical bone height was 10.8 mm (scale 7.5- 15.6 mm). An average bone gain of 7.2 mm was observed (range 2.5- 11.7 mm).
  
  
  CONCLUSIONS
  Based on the results of this study, during ultrasound sinus lift, few Schneiderian membrane perforations occurred and all were small .
