CT三维重建在成年汉族女性硅胶假体隆鼻术中的应用

CT three-dimensional reconstruction of augmentation rhinoplasty with silicone implants in adult Han women

目的 探讨成年汉族女性CT三维重建硅胶假体隆鼻术与常规硅胶假体隆鼻术术后相关美学参数及满意度。方法将60例自愿行硅胶假体隆鼻术成年健康汉族女性完全随机分成A，B两组，各30例；A组行CT三维重建硅胶假体隆鼻术，B组行常规硅胶假体隆鼻术，术后6个月进行相关数据测量及问卷调查，将所得出的主观和客观指标分别进行鼻根、鼻背、鼻头效果的综合分析比较。结果鼻尖角、鼻面角、鼻额角、鼻根高A组分别为（89．50±1．40）°，（28．85±2．20）°，（136．26±1．92）°，（6．45±0．27）mm，B组分别为（85．40±3．70）°，（26．43±4．39）°，（138．88±4．78）°，（5．28±0．34）mm，差异有统计学意义（P〈0．05）；手术时间A组为（51．77士5．35）min，B组为（29．83±5．76）min，差异有统计学意义（P〈0．05）。结论CT三维重建硅胶假体隆鼻术，因其术前假体目的性设计及术中避免局部肿胀影响等原因，其术后效果优于常规硅胶假体隆鼻术（特别对于鼻背及鼻根部），并可明显缩短手术时间，故此方法更适用于存在鼻根部及鼻背部缺陷的美容就医者。

Objective To evaluate the postoperative related aesthetic parameters and satisfacto- ry degree between CT 3D reconstruction augmentation rhinoplasty with silicone and augmentation rhinoplasty with silicone in adult Han women. Methods Totally 60 adult healthy Han women voluntarily subjected to augmentation rhinoplasty with silicone were randomly divided into groups A and B, 30 people each group; Row CT 3D reconstruction augmentation rhinoplasty with silicone was performed in group A, and the augmentation rhinoplasty with silicone in group B 6 months after surgery related data measurement and questionnaire collected, we compared the objective and subjective indicators for the nasal root, dorsum and ministry, respectively. Results There was a difference between group A and group B in the nasorostral angle, the nasal facial angle, the asofrontal angle and the height of the nasal root （89. 50±1. 40）°, （28.85±2. 20）°, （136.26±1.92）°, （6.45±0.27） mmin group A, and （85.40±3.70）°, （26.43±4.39）°, （138.88±4.78）°, （5. 28±0.34） mm in group B （all P〈0.05）. There was a difference between group A and group B in operation time （51. 77 ± 5. 35）min vs （29. 83±5.76） min （P〈0.05）. Conclusions Owing to its preoperative prosthesis design purpose and avoiding local swelling, CT 3D reconstruction augmentation rhinoplasty with silicone has better effects than that of augmentation rhinoplasty with silicone, especially on the nasal dorsum and the nasal root）, which can obviously shorten the operation time, and therefore it is more suitable for the defects of the nasal root and dorsum.
