Correction of cleft lip nose deformities using Ni-Ti shape memory alloy mesh stent implant

目的 探讨镍钛形状记忆合金 (NT SMA)网状支架置入矫正单侧唇裂鼻畸形的可行性。方法 对 6例 18～ 32岁单侧唇裂术后鼻畸形患者 ,通过鼻前庭切口置入NT SMA网状支架。结果 全部病例鼻翼较为对称 ,鼻尖外形良好 ,唇鼻协调。经半年～ 1年追踪复查未见任何并发症。结论 NT

Objective\ To demonstrate the feasibility of Ni Ti shape memory alloy mesh stent for the correction of nasal deformities caused by cleft lip. Methods\ Six patients with cleft lip nose deformities, aged from 18 to 32, were treated by implantation of Ni Ti shape memory alloy mesh stent through intra nasal incisions. Results\ The symmetry of the alar and nasal tip were cosmetically acceptable. Satisfactory relationship between the lip and the nose were obtained in all the patients. There were not any postoperative surgical complications by 6 to 12 months' follow up. Conclusion\ The Ni Ti shape memory alloy mesh stent is suitable for use in the correction of adult cleft lip nose deformities.\;
