目的:为同种异体移植鞍鼻畸形患者提供持久的美容和功能效果。
方法:本报告描述了在58例患者中使用冻干同种异体骨移植的经验,这些患者在5年内(2018-2023年)接受了背侧增强。38例病人有马鞍状的鼻子畸形,16例患者有创伤后鞍状鼻畸形。所有患者均使用计算机断层扫描进行临床检查。在手术前使用3D模型,根据鼻缺损的形状对移植物进行轮廓化。使用闭合方法安装移植物并将其放置在骨的骨膜下。使用横向照片,手术前后对鼻子进行人体测量,以评估手术后的美学效果。为了评估美学隆鼻(UQ)的结果,使用葡萄牙语版本的乌得勒支问卷,其中包含5点Likert量表的视觉模拟量表(VAS)。
结果:共有56例患者对手术结果感到满意。未观察到并发症或严重的移植物吸收。使用3D扫描比较术前和1年随访数据的分析表明,在没有背侧扩张的情况下,背侧高度显着增加。隆鼻后,平均视觉模拟量表(VAS)美学评分从术前的2.3显著提高,术后3个月8.4,术后1年8.9。
结论:使用冻干同种异体骨移植是一种在鼻部成形术中进行背侧扩大的有用方法,而没有供体部位的并发症。

OBJECTIVE: Providing lasting cosmetic and functional results for patients with saddle nose deformity with allograft.
METHODS: This report describes experience with using a of freeze-dried allograft bone allograft in 58 patients who underwent dorsal augmentation over 5-year period (2018-2023). Thirty-eight patients had saddle-shaped deformity of the nose, and 16 patients had post-traumatic cases with saddle nose deformities. All patients underwent a clinical examination using computed tomography. Before surgery using a 3D model, the graft was contoured according to the shape of the nasal defect. The grafts were installed using a closed approach and were placed under the periosteum of the bone. Using lateral photographs, anthropometric measurements of the nose were taken before and after surgery to assess aesthetic outcome after surgery. To assess the results of aesthetic rhinoplasty (UQ), the Portuguese version of the Utrecht Questionnaire was used, which contains a visual analogue scale (VAS) on a 5-point Likert scale.
RESULTS: A total of 56 patients were satisfied with the results of the surgical procedure. No complications or major graft resorption was observed. An analysis comparing preoperative and 1-year follow-up data using 3D scanning showed a significant increase in dorsal height without dorsal expansion. After rhinoplasty, the mean visual analog scale (VAS) aesthetic score improved significant from 2.3 preoperatively, 3 months postoperatively 8.4, and 8.9 1 year postoperatively.
CONCLUSIONS: The use of freeze-dried allograft bone is a useful method of dorsal augmentation in rhinoplasty without donor site complications.
