Abstract:
Tissue expansion is in widespread use for the reconstruction of congenital and acquired defects. Complications of tissue expansion are well documented, the most common being infection or extrusion of the expander. Although the complications associated with scalp tissue expansion are similar to those experienced elsewhere in the body, site-specific complications can occur. These include bone thinning and erosion of the cranial vault. In this study, we report an unusual case of multiple osteophyte formation beneath a scalp tissue expander, resulting in its rupture and necessitating removal.
