鼻尖几何多边形移植物鼻整形临床应用的疗效分析.

Objective To evaluate the clinical effect of costal cartilage sculpted polygonal nasal tip graft in rhinoplasty. Methods From June 2016 to December 2021, 368 patients with poor nasal tip shape underwent rhinoplasty with costal cartilage sculpted polygonal nasal tip graft. Postoperative complications, incision scar, nasal tip protrusion, nasal tip morphology improvement, and overall satisfaction were evaluated. Results All 368 patients were followed up for 12 to 46 months, and the nasal tip protrusion and shape of the patients improved well. Five patients showed a slight downward rotation of the nasal tip 12 to 19 months postoperation, and 4 patients showed a cartilaginous appearance of the nasal tip 12 to 16 months postoperation, which was improved after the second rhinoplasty. No flap necrosis, infection, delayed incision healing, or other complications occurred, no obvious incision scar formation and nasal tip skewed. Postoperative overall satisfaction was high, including 312 very satisfied cases, 45 satisfied cases, and 11 general cases, the satisfaction rate was 97.0%. Conclusion The application of costal cartilage sculpted polygonal nasal tip grafts in rhinoplasty has the following advantages. The graft is conformed to the anatomical and aesthetic characteristics of the nasal tip, can effectively reduce the height of the nasal tip strut, reduce the incidence of skewness, and reduce the tension of the alar cartilage and mucosa. The postoperative effect is good, the overall satisfaction of patients is high, and it is worthy of clinical popularization and application. [ABSTRACT FROM AUTHOR]
