Technological Innovation and Clinical Application of Nasal Foreign Body Removal and Tissue Reconstruction

This study, based on the “Technological Innovation in Foreign Body Removal and Tissue Reconstruction in Failed Nasal Plastic Surgery” project, addresses the challenges of removing nasal foreign bodies such as bone powder and polyacrylamide hydrogel (Omnipaque) and repairing deformed noses. With over 80 high-difficulty clinical cases, it explores the innovative aspects of the “layered dissection + precise debridement” technique and its application in nasal repair, as well as the stability of the “auricular cartilage + nasal septal cartilage” combined scaffold in nasal shape reconstruction. The results show that the “layered dissection + precise debridement” technique significantly increases the thoroughness of foreign body removal to 95%, compared to 70% of traditional methods, and reduces post-operative complications to 5%, down from 15% of traditional methods. The application of the “auricular cartilage + nasal septal cartilage” combined scaffold achieves a 90% satisfaction rate in nasal shape and good long-term stability. This study provides new technical ideas and clinical references for the repair of failed nasal plastic surgery, promoting the development and progress of nasal plastic repair technology, with significant clinical application value and social significance.
