Tissue expanders have been an accepted surgical technique in the treatment of traumatic, post-operative and other defects and loss of tissue since the 1980s. The expander is inserted in the hairy part of the scalp either subcutaneously or subgaleally above the periosteum, thus enabling the skin lobe, including hair follicles, to develop normally.
One of the major complications is the poor choice of location for the tissue expander. In the case report, we will present that 3D modeling from CT and subsequent 3D printing can help to plan its most suitable location.
