In this paper, MSNs were synthesized by a template method, and the morphology and pore structure were regulated.

The clinical application and anatomical analysis of proximal peroneal artery perforator in free fibula flap based on CTA.

Background: The vascularized free fibular flap is increasingly recognized as the standard technique for the repair of complex soft tissue and hard tissue defects in oral and maxillofacial surgery.
