A systematic approach to treating glabella-radix deficiency is lacking, and the management of brow-tip aesthetic lines remains technically challenging.
The authors describe implantation of a customized Gore-Tex prosthesis combined with primary augmentation rhinoplasty to address the glabella-radix deficiency.
Fifty Asian patients with glabella-radix deficiency who received implantation and primary augmentation rhinoplasty were retrospectively evaluated in an 8-year period. Patients were assigned to categories based on brow-tip contour lines and symmetry patterns, and implant dimensions were ascertained from the contour type and from simulated postoperative results.
Eleven men and 39 women were included in the study; the mean patient age was 27.22 years, and mean follow-up was 22.8 months. Seven of the patients were assigned to the type I/Ia category, 24 to type II/IIa, and 19 to type III/IIIa. Forty-five patients were considered to have satisfactory surgical results, with curved, symmetric, and normally spaced brow-tip lines on front view and a smooth frontonasal transition on profile view. Complications occurred in 5 patients and included infection (1 patient), inadequate augmentation (2), and palpable margin folding of the Gore-Tex device (2).
Deformities of brow-tip contour lines coincide with glabella-radix deficiencies in terms of severity. Knowledge of the patterns of brow-tip lines, combined with postoperative image simulation, can help the surgeon design an appropriate glabella-radix prosthesis. When placed in conjunction with other augmentation rhinoplasty procedures, the glabella-radix implant yields sufficient, predictable nasal projection and a harmonious facial aesthetic.
目前缺乏一种系统的方法来治疗眉间-鼻根凹陷，并且处理眉梢美学线在技术上仍然具有挑战性。
作者描述了定制的戈尔特斯（Gore-Tex）假体植入联合初次隆鼻术以解决眉间-鼻根凹陷问题。
回顾性评估了50例接受假体植入和初次隆鼻术的亚洲眉间-鼻根凹陷患者，为期8年。根据眉梢轮廓线和对称模式将患者分类，并根据轮廓类型和模拟术后结果确定植入物尺寸。
研究纳入11名男性和39名女性；患者平均年龄为27.22岁，平均随访时间为22.8个月。7例患者被归类为I/Ia型，24例为II/IIa型，19例为III/IIIa型。45例患者被认为手术结果满意，正面观眉梢线弯曲、对称且间距正常，侧面观额鼻过渡平滑。5例患者出现并发症，包括感染（1例）、隆高不足（2例）以及戈尔特斯装置边缘可触及褶皱（2例）。
眉梢轮廓线畸形在严重程度上与眉间-鼻根凹陷相符。了解眉梢线模式并结合术后图像模拟，有助于外科医生设计合适的眉间-鼻根假体。当与其他隆鼻手术联合进行时，眉间-鼻根植入物可产生足够的、可预测的鼻突出度并实现面部美学和谐。
