Derotation of the nasal tip with narrow nasolabial angle is a common nasal deformity that leads to a long nose appearance, named drooping nose. In these patients, there are various techniques described to fix droopy tip and to achieve a desirable nasal tip rotation such as caudal septal extension graft, extended columellar strut graft, tongue in groove, columellar strut graft, and tip rotation sutures. This study aimed to evaluate changes in nasal tip support after modified tongue-in-groove technique (auto-septal projection graft).
Forty-two patients who underwent a primary open approach septorhinoplasty using the modified tongue-in-groove technique between June 2017 and March 2019 were retrospectively analyzed. Postoperative and preoperative photographs were analyzed, and nasolabial angle and the nasal tip projection ratio were recorded and compared before and average of 17.3 months after the surgery.
Forty-two patients (33 female and 9 male) were included the study. The mean nasolabial angle was 85.7° preoperatively and 99.3° postoperatively. The nasal tip projection ratio was 0.60 preoperatively and 0.64 postoperatively. Both the tip rotation and the tip projection increased significantly after the modified tongue in groove (p<0.05).
It seems that modified tongue-in-groove method (auto-septal projection graft) is an effective technique in maintaining tip projection and rotation in rhinoplasty and safe method to correct droopy nasal tip in selected cases.

鼻尖旋转伴狭窄鼻唇角是一种常见的鼻畸形，导致长鼻外观，称为垂鼻。在这些患者中，有各种技术被描述来固定下垂的鼻尖并实现理想的鼻尖旋转，如鼻中隔尾侧延伸移植物、延长鼻中隔支撑移植物、榫舌入槽、鼻中隔支撑移植物和鼻尖旋转缝线。本研究旨在评估改良榫舌入槽技术（自体鼻中隔突出移植物）后鼻尖支撑的变化。
回顾性分析了 2017 年 6 月至 2019 年 3 月期间采用改良榫舌入槽技术行初次开放式鼻中隔成形术的 42 例患者。分析术后和术前照片，并记录和比较术前和术后平均 17.3 个月的鼻唇角和鼻尖突出比。
42 例患者（33 名女性和 9 名男性）纳入本研究。术前鼻唇角平均为 85.7°，术后为 99.3°。术前鼻尖突出比为 0.60，术后为 0.64。改良榫舌入槽后鼻尖旋转和鼻尖突出均显著增加（p<0.05）。
改良榫舌入槽法（自体鼻中隔突出移植物）似乎是一种有效的鼻整形术维持鼻尖突出和旋转的技术，也是矫正特定病例下垂鼻尖的安全方法。
