To discuss overprojected nasal tips, to overview treatment options, and to introduce a new method of nasal tip modification.
A retrospective study was conduced on 29 patients who underwent rhinoplasty where the domes crossover technique was employed. Patients were stratified into 3 groups: 18 patients presented with homogeneous overdevelopment of the LLC (nasal tip over projection type 1), 5 patients with predominant over development of the lobular portion of the LLC (nasal tip overprojection type 2), 6 patients with a true Pinocchio-type nose and a predominant overdevelopment of the columellar portion of the LLC (nasal tip overprojection type 3). Before and after photographs were compared to evaluate nasal tip characteristics. Analysis of results was performed by the use of 3 measurements: Goode's ratio, nasofacial angle and lobule-to-columella ratio.
Final nasal tip projection, rotation, volume and shape were satisfactory in all cases. No complication was observed during the follow-up period.
This new method of nasal tip modification presents the advantage of preserving natural domes, being quick and allowing the achievement of desirable nasal tip projection, rotation, volume and shape. Moreover according to the alar ring concept, the crossover technique preserves the continuity of the inferior cartilaginous arch and gives an excellent support to nasal tip.
探讨鼻尖过度上翘，概述治疗方案，并介绍一种新的鼻尖整形方法。
对29例行隆鼻术并采用穹窿交叉技术的患者进行回顾性研究。患者分为3组：18例表现为外侧脚软骨均匀过度发育（鼻尖过度上翘1型），5例以外侧脚软骨小叶部分过度发育为主（鼻尖过度上翘2型），6例为真正的匹诺曹鼻型且以鼻中隔部分过度发育为主（鼻尖过度上翘3型）。比较术前和术后照片以评估鼻尖特征。通过3项测量进行结果分析：古德比率、鼻面角和小叶与鼻中隔比率。
所有病例的最终鼻尖突出度、旋转度、体积和形状均令人满意。随访期间未观察到并发症。
这种新的鼻尖整形方法具有保留自然穹窿、操作快速且能实现理想的鼻尖突出度、旋转度、体积和形状的优点。此外，根据鼻翼环概念，交叉技术保留了下软骨弓的连续性，并为鼻尖提供了良好的支撑。
