Application of 3D-printed rehabilitation aids for hypertrophic scars

Hypertrophic scars (HS) are fibrotic proliferative diseases that develop after deep skin injuries caused by trauma, burns, and surgery. Traditional treatment methods include both surgical and nonsurgical therapies. Early intervention and combination therapy tailored to the individual needs of the patients are crucial for achieving optimal results. Three-dimensional (3D) printing technology, a rapid prototyping technique, is increasingly being applied in the medical field. The customization and precise functionality of 3D printing technology are particularly important for the rehabilitation of HS. This review provides an overview of HS and the role of 3D printing technology in medical applications, analyses the application of 3D-printed rehabilitation aids for HS, and discusses the use of 3D printing technology to improve HS treatment outcomes, thereby providing clinical guidance for effective HS rehabilitation.
