Recently, many commercial one-piece alloplastic materials are used in nasal dorsum augmentation and increased nasal tip projection, but there is no study about their effects with regard to size on nasal shape so far. The aim of this study is to evaluate the impact of oversized one-piece alloplastic implant on nasal tip projection.
We categorized nasal tip drooping as primary (group 1: no rhinoplasty or trauma history) and secondary (group 2: previous history of augmentation rhinoplasty with one-piece alloplastic materials), and retrospectively compared the characteristics of primary and secondary nasal tip drooping on the basis of pre- and postoperative rhinological parameters (nasolabial angle [NLA], rotation angle, nasofrontal angle [NFA], and Goode ratio).
A total of 50 patients were enrolled and completely reviewed. The mean age was 27.46 years (ranging from 19 to 49 years) in group 1 and 31.33 years (ranging from 20 to 47 years) in group 2. The postoperative NLA and rotation angle were not statistically different between 2 groups, but the postoperative NFA and postoperative Goode ratio were statistically different between 2 groups by independent test. When we further performed univariate and multivariate analysis, the postoperative Goode ratio was the only factor that was significantly different between the 2 groups.
Insertion of one-piece alloplastic implants from nasal tip glabella to dome of nasal tip may induce secondary nasal tip drooping. The degree of recovery of nasal tip projection is different between 2 groups and may be obtained by a more delicate surgical techniques.
最近，许多商业性的一体式假体材料被用于鼻背增高和鼻尖突出，但目前还没有关于这些材料大小对鼻形影响的研究。本研究旨在评估超大一体式假体植入物对鼻尖突出度的影响。
我们将鼻尖下垂分为原发性（无鼻整形或外伤史，组 1）和继发性（有一体式假体材料的鼻整形史，组 2），并基于术前和术后鼻科学参数（鼻唇角[NLA]、旋转角、鼻额角[NFA]和古德比[Goode 比值]）对原发性和继发性鼻尖下垂的特征进行回顾性比较。
共纳入 50 例患者并进行了完整的回顾。组 1 的平均年龄为 27.46 岁（19-49 岁），组 2 的平均年龄为 31.33 岁（20-47 岁）。两组间术后 NLA 和旋转角无统计学差异，但术后 NFA 和术后 Goode 比值有统计学差异。进一步进行单因素和多因素分析，发现只有术后 Goode 比值是两组之间有显著差异的唯一因素。
从鼻尖到鼻尖穹窿插入一体式假体可能会导致继发性鼻尖下垂。两组鼻尖突出度的恢复程度不同，可能需要更精细的手术技术。
