Using objective anthropometric measurement, this study reports the outcome of surgical correction of short-nose deformities in Asian patients.
To present our experience in lengthening the short nose in Asians and report the surgical results.
DESIGN, SETTING, AND PATIENTS: In this retrospective review, we study the cases of 36 patients who underwent surgical correction of short-nose deformity. The effect of nasal lengthening was analyzed using anthropometric measurement, including nasion to tip-defining point (N-TDP), nasal tip projection (NTP), nasofrontal angle (NFA), and columellar-facial angle (CFA).
Surgical correction of short-nose deformity.
The preoperative and postoperative N-TDP, NTP, NFA, and CFA and patient satisfaction.
The mean postoperative follow-up duration was 29.8 months. The cause of the short nose was congenital in 18 cases and secondary to previous rhinoplasty in 18 cases. Septal tissue, conchal cartilage, costal cartilage, and conchal composite tissue were used as graft materials. The key procedures for lengthening included septal extension graft reinforced with extended spreader, dorsal onlay, and tip grafts. The N-TDP increased by 11.2%, and CFA decreased from 122.6° to 111.1°. The NFA changed from 148.9° to 148.5°. The NTP ratio, measured using the Goode method, decreased from 0.53 to 0.50. The increase of N-TDP was greater in patients undergoing the costal cartilage grafting procedure than in those who received septal or conchal cartilage. All patients were satisfied with the aesthetic results, and there were no serious complications.
In Asians, the key maneuvers for lengthening were septal extension graft reinforced with extended spreader and dorsal onlay graft. Rib cartilage provided superior lengthening effect compared with other cartilage.
本研究通过客观的人体测量学评估，报告了亚洲患者短鼻畸形矫正手术的结果。
介绍我们在亚洲人短鼻延长术中的经验，并报告手术结果。
设计、环境和患者：在这项回顾性研究中，我们研究了 36 例接受短鼻畸形矫正手术的患者。使用鼻根到鼻尖定义点（N-TDP）、鼻尖突出度（NTP）、鼻额角（NFA）和鼻中隔-面部角（CFA）等人体测量学评估鼻延长效果。
短鼻畸形矫正手术。
术前和术后 N-TDP、NTP、NFA 和 CFA 以及患者满意度。
平均术后随访时间为 29.8 个月。18 例为先天性短鼻，18 例为继发于既往鼻整形术的短鼻。鼻中隔组织、耳软骨、肋软骨和耳软骨复合组织被用作移植物材料。延长的关键手术步骤包括鼻中隔延长移植物，并用延长型撑开器加强、背侧覆盖和鼻尖移植物。N-TDP 增加了 11.2%，CFA 从 122.6°减少到 111.1°。NFA 从 148.9°变为 148.5°。使用 Goode 方法测量的 NTP 比值从 0.53 降至 0.50。接受肋软骨移植的患者 N-TDP 增加幅度大于接受鼻中隔或耳软骨移植的患者。所有患者对美学效果均满意，且无严重并发症。
在亚洲人中，延长的关键操作是鼻中隔延长移植物，并用延长型撑开器加强和背侧覆盖移植物。肋软骨提供的延长效果优于其他软骨。
