A method of sealing perforated sinus membrane and histologic finding of bone substitutes: a case report.
To augment the atrophic posterior maxilla, a sinus bone graft has been widely used for sinus floor augmentation. Various bone substitutes have been developed and grafted in the maxillary sinus with and without membranes perforation, although autogenous bone is recommended as a gold standard of grafting materials. Membrane perforation is the most common complication associated with sinus bone graft. To repair a perforation, various methods have been developed. This case report is focused on histologic findings of 1 bovine hydroxyapatite (Bio-Oss; Geistlich Pharma AG, Wolhusen, Switzerland) and 2 kinds of human mineral allograft- Tutoplast cancellous microchips (TutoGen Medical GmbH, Neunkirchen am. Brand Germany), and irradiated allogeniccancellous bone and marrow (ICB; Rocky Mountain Tissue Bank, Aurora, CO) used for sinus graft in the same patient with membrane perforation after various healing periods. Mineral allograft showed favorable new bone regeneration with the repair of membrane perforation. This case report also describes a technique regarding how to repair completely perforated sinus membrane after the removal of a mucocele using human collagen membrane (Tutoplast pericardium; TutoGen Medical GmbH) and fibrin adhesive (Greenplast; Green Cross Co., Youngin, Korea) to stabilize collagen membrane.
