[Advances in the application of three-dimensional photothermal functionalized scaffold for bone repairation after maxillofacial tumor surgery].

The traditional treatment of maxillofacial tumors includes surgery and chemoradiotherapy. Surgery carries a high risk,and large bone defects are difficult to repair themselves. Besides, chemoradiotherapy can bring serious side effects. Therefore, how to repair the bone defects after maxillofacial tumor surgery and prevent tumor recurrence has become a major clinical challenge. In recent years, photothermal therapy has attracted much attention because of its low invasion, high efficiency, and no side effects. More and more photothermal materials have emerged and been applied in photothermal therapy. In order to treat tumor-related bone defects, many studies use three-dimensional printing technology to prepare photothermal functionalized scaffold to repair bone defects and prevent the recurrence of tumors. Based on photothermal therapy, the review states the photothermal materials, bone repair materials and photothermal functionalized scaffolds in the treatment of maxillofacial tumors at home and abroad, and provides a new way to solve the clinical challenge of bone defect and tumor recurrence after maxillofacial tumor surgery.
