Use of Intra-Oral Osmotic Self-Inflating Tissue Expanders for Bone Reconstruction and Rehabilitation of the Jaws
Reconstruction of oral and maxillofacial defects is challenging. Insufficient soft tissues may render hard tissue reconstruction problematic. Several surgical techniques have been used over time to address this issue; these techniques are usually complicated and unpredictable. Soft tissue expansion is a physiological process that leads to the formation of new cells and growth of tissue and allows for soft tissue with similar color, texture and function to that of the adjacent tissues. In this article we present the applications of osmotic tissue expanders in facilitating bone graft augmentation. OSMED (Ilmenau, Germany) self-inflating tissue expanders were used prior to bone augmentation in our patients. After making a 1.5 cm full thickness incision, a sub-periosteal tunnel was prepared and the tissue expander was implanted sub-periosteally. The tissue expanders were removed approximately 6–10 weeks later in the course of augmentation surgery. In all patients after the use of the tissue expander, sufficient soft tissue was available for primary, tension-free, wound closure and there was no need for local or regional flap techniques. No complications such as infection, necrosis, or graft loss occurred and the functional and esthetic outcomes were acceptable. Use of this tissue expander prior to bone augmentation was effective in facilitating bone graft augmentation.
