| A major goal of maxillary antrostomy is to increase sinus ventilation. |
| No perforation occurred during the antrostomy and the initial membrane elevation with piezoelectric inserts. |
| We sought to quantify the effect of uncinectomy, small antrostomy, and large antrostomy on maxillary sinus ventilation using xenon-enhanced CT in the sheep model. |
| Rotary instruments, piezoelectric osteotomes, and manual bone scrapers were used to perform the lateral antrostomy. |
| Considering the configuration of new bone formation, it was decided to perform the palatal antrostomy approach. |
| The most common surgical procedures included sphenoidectomy, ethmoidectomy, maxillary antrostomy, and middle turbinectomy. |
