BACKGROUND: Perforation of maxillary sinus mucous membrane is one of the most prevalent complications during open sinus lift surgery. Moreover, such complication can usually be managed by an absorbable membrane. As far as absorbable membranes are concerned, decellularized maxillary sinus mucous membrane, which is an extracellular matrix, can be used as a biologic scaffold and an insulating membrane in sinus lifting surgery.
MATERIALS AND METHODS: The decellularization process of the maxillary sinus membrane was performed by means of physical and chemical procedures (liquid nitrogen and sodium dodecyl sulfate). Then this membrane was used as a bioscaffold for culturing with adult mesenchymal stem cells, which were derived from adipose tissue.
RESULTS: Histologic evaluation of the decellularized scaffold revealed that cells of the Schneiderian membrane were compatibly removed via SDS 1%. Moreover, the scan with electron microscope (S6N - Leo vp1450, Germany) of the scaffold indicated that the collagen fibers of the decellularized maxillary sinus membrane were intact. Furthermore, the culture studies carried out showed that this scaffold supported cell seeding.
CONCLUSION: The decellularized human maxillary Schneiderian membrane has a 3D structure similar to that of the extracellular matrix of human normal tissues. As a matter of fact, it can be used as a bioscaffold to support cell seeding.
