Ptosis of the nasal tip is one of the most challenging aspects of rhinoplasty, and the tongue-in-groove (TIG) and the columellar strut (CST) techniques are the two most common procedures used to improve it. The purpose of this study was to introduce a new modification of TIG, to evaluate the long term results of the modified TIG, and to compare its effect on correction of the nasolabial angle with that of the CST. Eighty patients with droopy nasal tips (all female, aged <40 years) were divided into two groups of 40 each according to the technique used for correction (modified TIG or CST). The nasolabial angle was recorded preoperatively, immediately postoperatively, and after one year. The mean was 90.80° in the modified TIG group and 94.87° in the CST preoperatively, which did not differ significantly (p=0.056). Immediately postoperatively, it was significantly higher in the CST group (116.92° compared with 107.10°, p=0.01), but at the one-year follow-up, the droop was similar in both groups (-7.35° in the modified TIG, and -7.48° in the CST group, respectively, p=0.942). Both techniques significantly increased the nasolabial angle postoperatively (p<0.001 in both cases). This study showed that the modified TIG is a reliable and effective technique for reconstructing and correcting a droopy nasal tip, and its long-term efficacy is comparable with that of CST.
鼻尖下垂是鼻整形术中最具挑战性的方面之一,榫槽(TIG)和鼻小柱支撑(CST)技术是用于改善该问题的两种最常见手术方法。本研究的目的是介绍一种TIG的新改良方法,评估改良TIG的长期效果,并将其对鼻唇角矫正的效果与CST的效果进行比较。80例鼻尖下垂患者(均为女性,年龄<40岁)根据矫正所用技术(改良TIG或CST)分为两组,每组40例。术前、术后即刻和术后一年记录鼻唇角。改良TIG组术前平均为90.80°,CST组术前平均为94.87°,差异无统计学意义(p = 0.056)。术后即刻,CST组显著更高(116.92°对比107.10°,p = 0.01),但在一年随访时,两组的下垂情况相似(改良TIG组为-7.35°,CST组为-7.48°,p = 0.942)。两种技术术后均显著增加了鼻唇角(两种情况均p<0.001)。本研究表明,改良TIG是一种可靠且有效的重建和矫正鼻尖下垂的技术,其长期疗效与CST相当。
