本研究的目的是评估开放鼻成形术患者可用于移植的鼻中隔软骨的尺寸，并分析外鼻的大小是否可能是可收获的鼻中隔软骨的大小和数量的有用指标。对55名韩国鼻整形患者进行了前瞻性研究。术中测量切除的间隔软骨，保留10 mm宽的l -支撑。评估了中隔软骨原位数量和大小与人体测量值之间的相关性。切除的中隔软骨尾端平均长度为15.1 mm，背端平均长度为18.2 mm，平均面积为520.9 mm(2)。仅有5例（9.1%）患者有足够的软骨进行全长背片移植，而10例（18.2%）患者有长度为bb0 ~ 25mm的鼻中隔软骨可以作为扩展移植。鼻中隔软骨原位尺寸与术前外鼻测量结果无关。在韩国，切除的中隔软骨数量通常不足以同时用于多次移植。外鼻大小可能不是一个有用的指标，可用足够的鼻中隔软骨隆鼻。在术前计划鼻整形手术时，需要收集额外的移植物材料。
The aim of this study was to assess the dimensions of the septal cartilage available for grafting in patients undergoing open rhinoplasty and analyze whether the size of the external nose might be a useful indicator of the size and amount of harvestable septal cartilage. A prospective study was conducted on 55 Korean rhinoplasties. Intraoperative measurement of the harvested septal cartilage with preservation of 10 mm width L-strut was performed. The correlation between the quantity and size of the septal cartilage in situ with anthropometric measurements were evaluated. The mean caudal length of the harvested septal cartilage was 15.1 mm, the mean dorsal length was 18.2 mm, and the mean area was 520.9 mm(2). Only 5 patients (9.1%) had cartilage sufficient for full-length dorsal onlay grafts, whereas 10 patients (18.2%) had septal cartilages of length >25 mm that could be used as spreader grafts. Dimensions of the septal cartilage in situ did not correlate with preoperative external nose measurements. The amount of harvested septal cartilage is usually insufficient for simultaneous use for multiple grafts in Korean. External nose size may not be a useful indicator of the availability of adequate septal cartilage for rhinoplasty. The need to harvest additional graft material should be kept in mind during preoperative planning for rhinoplasty procedures.
