Membrane Perforation of sinus graft surgery

it is the most common complication during the sinus graft surgery resulting from the scoring of lateral access window for surgery and when elevating the membrane from the bony walls. Small size tear can be sealed by initially elevating membrane from all sides (circumelevation) and then in the tear region excess membrane seals the hole. Larger size tear requires a resorbable collagen membrane of longer resorption cycle.
