RESUMO
Objective:To investigate the effect of autologous costal cartilage cortex as nasal tip support and modified graft for nasal tip contour improvement.Methods:From June 2020 to June 2021, 116 patients (male 26, female 90, aged 20-45 years) who received rhinoplasty in the cosmetic surgery department of Myoung Beaucare Clinic of Beijing, were examined the costal cartilage by CT, and the costal cartilage was cut. The costal cartilage cortex was made into " strip" and " cap" grafts to shape the nasal tip, and the nasal dorsum was raised by polytetrafluoroethylene or silicone prosthesis for comprehensive rhinoplasty.Results:A total of 116 patients were followed up for an average of 11.7 months. After the operation, there was no space occupying in the nasal cavity, no graft protrusion, no obvious foreign body feeling in the nasal valve, and the nasal tip could swing left and right. At the same time, the nasal tip showed obvious signs, the lower lobule was full, and there were no complications such as cartilage appearance, exposure, infection, etc. Due to the untreated deviation of nasal septum, 3 cases had deviation of nasal columella and asymmetric nostrils. The shape of nasal tip was stable in the remaining 113 cases, and satisfactory results were obtained.Conclusions:By using autologous costal cartilage cortex as nasal tip support and modification graft for nasal tip contour improvement, the shaped nasal tip is soft and movable, and does not affect the airway. It is a good surgical technique in nasal tip plastic surgery, which is worthy of clinical application.
