A Comparative Analysis Between Primary and Secondary Nasal Tip Drooping.

OBJECTIVE

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.

METHODS

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).

RESULTS

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.

CONCLUSION

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.
