Modified double-layered flap technique for closure of an oroantral fistula: Surgical procedure and case report

Abstract Several techniques have been used to close oroantral communications, and they vary in their difficulty of execution and success. We present the “modified double-layered flap technique”, which is similar to the treatment of labiopalatoschisis, has a high rate of success that is dependent on the skill of the surgeon, and will involve a steep learning curve.
