Abstract：
BACKGROUND: Correction of asymmetry and irregularity deformities with autologous grafts, without osteotomies, offers advantages to both plastic surgeons and patients with severe deviation. Various autologous tissues such as fat, bone, and cartilage grafts are viable options for this purpose.
OBJECTIVE: This study aimed to compare the efficacy of 3 autologous filling materials in patients with bone asymmetry.
METHODS: A retrospective evaluation was conducted on 297 patients seeking aesthetic nose surgery between 2015 and 2022. Only primary patients without prior surgery and those with bone asymmetry from trauma, with dorsum protrusion <3 mm, and without osteotomy were included. Patients were divided into fat, cartilage, and bone groups. Grafts were applied to the concave side during closed rhinoplasty, and evaluations were done 12 months after surgery by blinded plastic surgeons and patients using established assessment tools.
RESULTS: Fat, cartilage, and bone grafts were utilized in 74, 127, and 96 patients, respectively, with a mean follow-up of 19 months. The mean graft volumes were 1.0 cc (bone), 1.3 cc (cartilage), and 1.6 cc (fat). The patient self-assessment scores were 75%, 84.9%, and 86.6%, respectively. The Asher-McDade averages were 77.2%, 86.7%, and 88.4%, respectively. Cartilage and bone graft results were statistically similar in patients\' self-evaluation and significantly higher than those of fat grafts. Blinded assessments showed no significant difference between the cartilage and bone groups.
CONCLUSIONS: Placing autologous grafts on the concave side for patients with minimal nasal bone protrusion (<3 mm) yields successful results. Cartilage grafts offer advantages in volume, result estimation, and preparation time, making them suitable for larger patient cohorts.

摘要：
背景：用自体移植物矫正不对称和不规则畸形，没有截骨术，为整形外科医生和严重偏差的患者提供了优势。各种自体组织，如脂肪，骨头,和软骨移植物是可行的选择。
目的：本研究旨在比较3种自体填充材料在骨不对称患者中的疗效。
方法：对2015年至2022年间297例寻求鼻美容手术的患者进行了回顾性评估。只有未经手术的原发患者和因创伤而骨骼不对称的患者，背突起<3mm,没有截骨术也包括在内。患者被分为脂肪，软骨，和骨群。在闭合隆鼻术中，将移植物应用于凹侧，术后12个月,盲症整形外科医生和患者使用既定的评估工具进行评估.
结果：脂肪，软骨，在74、127和96名患者中使用了骨移植物，分别,平均随访19个月。平均移植物体积为1.0cc（骨），1.3cc（软骨），和1.6cc（脂肪）。患者自评评分为75%,84.9%,和86.6%，分别。Asher-McDade的平均值为77.2%,86.7%,和88.4%，分别。患者自我评估的软骨和骨移植结果在统计学上相似，并且明显高于脂肪移植。盲目评估显示软骨组和骨骼组之间没有显着差异。
结论：对于鼻骨突出程度最小（<3mm）的患者，在凹侧放置自体移植物可以获得成功的结果。软骨移植物在体积上具有优势，结果估计，和准备时间,使他们适合更大的患者队列。
