Application of costicartilage in rhinoplasty repair surgery

Abstract

Objective To investigate the clinical application and effect of autogenous costal cartilage in rhinoplasty repair surgery. Methods From July 2015 to June 2018, 112 cosmetic patients were treated with costal cartilage nasal tip prosthesis in the Department of Cosmetic Surgery, Shanghai Yixing Medical and Beauty Hospital. By using the straight part of the ribs, the nasal columella was made with mortise groove and then septal expanded graft prepared by using two pieces of expanded grafts. The cap-like, shield-like cartilage and perichondrium were combined for completing nasal tip prosthesis. Results A total of 112 patients were treated after rhinoplasty repair surgery. After 6-24 months of follow-up, 100 (accounting for 89.3%) cosmetic seekers were satisfied with the shape of the nasal tip, 5 (accounting for 4.5%) of those patients were not being satisfied due to unexpected nasal tip point, 3 (accounting for 2.7%) surgical infection cases after rhinoplasty and underwent prosthesis removal, 2 (accounting for 1.8%) had slight deviation of nasal tip and 2 had partial necrosis of nasal septum mucosa. No pneumothorax or chest wall deformities were found. Conclusions Rib cartilage is an excellent material for nasal tip formation in rhinoplasty. The use of autogenous costal cartilage to repair aesthetic defects in the lower nose can achieve a more effective, safe and lasting effect.
