Abstract

|
|
Sinus membrane perforation is the most common intraoperative complication of sinus elevation. Anatomic drawback of sinus is one of the risk factor to perforate its membrane. Prevalence of perforation during sinus lift accessed by alveolar crest is less than that of by lateral window. To repair the laceration of Schneiderain membrane, the resorbable collagen membrane is mostly covered the perforated area, through lateral approach. However, in this report, the perforated sinus membrane is repaired with resorbable collagen membrane through the socket. On six months after loading, new bone under sinus floor would be found. Of course, it needs to study further, but it could attempt to repair the sinus membrane perforation via transalveolar approach without formation of bony window.
