Application of costal cartilage cortex for nasal tip contour improvement
Objective To investigate the efficacy of autologous costal cartilage cortex as a nasal tip support and modification graft in improving the nasal tip morphology.Methods From March 2021 to June 2022,89 patients who underwent rhinoplasty with a focus on nasal tip shaping were enrolled.CT scans were used as an auxiliary examination,and costal cartilage was harvested.The cortical layer of the costal cartilage was shaped into"plate-like"and"cap-like"grafts to sculpt the nasal tip morphology,while expanded polytetrafluoroethy-lene(ePTFE)or silicone implants were used to elevate the nasal dorsum.Photometric methods were employed to obtain the patients'nasofa-cial parameters,which were then compared before and after surgery to observe patient satisfaction and the occurrence of complications.Results All 89 patients were followed up for 6 to 24 months,with an average of 9 months.Postoperatively,there were no intranasal occu-pations or graft protrusions.Patients reported no foreign body sensation in the external nasal valve upon self-examination,and the nasal tip was able to move laterally.The nasal tip exhibited distinct tip-defining points,a full lower lateral cartilage lobule,and no complications such as cartilage visibility,exposure,or infection.Two patients experienced deviation of the nasal columella and asymmetrical nostrils due to unaddressed septal deviation.Measurement results showed significant improvements in postoperative nasal length,nasal tip rotation,na-sofrontal angle,and nasal tip projection,with statistically significant differences compared to preoperative values(P＜0.05).Conclusion The application of autologous costal cartilage cortex as a nasal tip support and modifying graft to improve nasal tip morphology is a good surgical technique.The shaped nasal tip is soft and movable without affecting the airway,making it worthy of clinical application.
