Nasal tip projetion and definition are essential parameters which should be considered in the preoperative rhinoplasty plan. Jonhson and Toriumi have defined a technique of rhinoplasty to restructure the lobule using columellar strut and tip grafts. The aim of this study was to define the influence of this procedure on nasal tip projection, using the Goode method (objective measurement of the tip projection).
Forty patients underwent primary rhinoplasty, by open approach, with remodeling of the lobule using cartilagenous grafts, according to Jonhson and Torium technique. Goode ratio was calculated to assess tip projection preoperatively and postoperatively, based on photographic analysis. Moreover, postoperatively, all patients were clinically evaluated at 2, 4 and 6 months, and based on photographs of face at 2 and 6 months.
Five hypoprojected preoperative nasal tips (Goode ratio (GR): 0,45 to 0,51) had a normal nasal tip projection postoperatively (GR: 0,55 to 0,59). Among the eight normal projected preoperative nasal tips (GR: 0,56 to 0,60), six had a normal postoperative nasal tip projection while two showed a hyperprojection (GR: 0,62 and 0,63). Among the 27 hyperprojected preoperative nasal tips (GR: 0,62 to 0,75), 17 showed a normal projection of the nasal tip postoperatively while 10 remained hyperprojected despite a decreased Goode ratio.
Restructuration of the lobule, using cartilagenous grafts, is a reliable and reproducible technique allowing satisfying aesthetic results and objective measurements of the changes in nasal tip projection using the Goode method.
鼻尖突出度和清晰度是鼻整形术前计划中应考虑的重要参数。约翰逊和鸟海定义了一种鼻整形技术,即使用鼻中隔支柱和鼻尖移植物来重塑鼻尖小叶。本研究的目的是使用古德法(鼻尖突出度的客观测量方法)来确定该手术对鼻尖突出度的影响。
40例患者接受了开放式初次鼻整形手术,根据约翰逊和鸟海技术,使用软骨移植物重塑鼻尖小叶。基于照片分析计算术前和术后的古德比率,以评估鼻尖突出度。此外,术后在2、4和6个月对所有患者进行临床评估,并根据2个月和6个月时的面部照片进行评估。
术前5个鼻尖低突出度的患者(古德比率(GR):0.45至0.51)术后鼻尖突出度正常(GR:0.55至0.59)。术前8个鼻尖正常突出度的患者(GR:0.56至0.60)中,6个术后鼻尖突出度正常,而2个显示鼻尖过度突出(GR:0.62和0.63)。术前27个鼻尖过度突出的患者(GR:0.62至0.75)中,17个术后鼻尖突出度正常,而10个尽管古德比率降低但仍保持过度突出。
使用软骨移植物重塑鼻尖小叶是一种可靠且可重复的技术,能产生令人满意的美学效果,并能用古德法对鼻尖突出度的变化进行客观测量。
