Abstract: Objective To explore the application of multi-plane hyaluronic acid injection in rhinoplasty using blunt and sharp needle technique. Methods From June 2011 to February 2014, 285 cases received rhinoplasty by multi-plane hyaluronic acid injection with blunt and sharp needle technique. All the cases were injected for 1-3 times at intervals of 6-14 months, and were followed up for postoperative effect evaluation. Results All the patients were followed up for 1-9 months. No complications were observed, such as nasal root broadening, vifrification, infection, local induration or flap necrosis. The nose shape was smooth and natural. Conclusion Multiplane hyaluronic acid injection using blunt and sharp needle technique in rhinoplasty is safe and effective, and is worthy of clinical promotion.
