Nasal tip surgery is the most important and most difficult step of an aesthetic rhinoplasty operation. Various suture and grafting techniques have been described for adequate tip rotation and projection in nasal tip surgery.
The author describes his technique of "three-dimensional (3D) columellar strut graft" in nasal tip surgery.
Each patient is treated using the open technique rhinoplasty. The author's technique uses a 3D dorsal columellar strut with a special anatomy in the shape of a Y- on a horizontal plane. When the dorsal columellar strut is placed in a way to maintain the interdomal angle, this technique perfectly stabilizes the lower lateral cruses (LLCs) that have been shaped with cephalic dome suture (CDS).
A retrospective analysis of 78 patients, who underwent 3D columellar strut graft technique, were included in the study. The mean follow-up period was 15 months. All of the patients were satisfied with their tip shapes.
The 3D dorsal columellar strut graft technique is an easily administered technique with reliable outcomes. The purpose of this graft is to support the reshaped LLCs with a perfect anatomic alignment. It does not require any additional cartilaginous graft in patients undergoing a reduction of the dorsum.
鼻尖手术是鼻整形美容手术中最重要且最具挑战性的步骤。在鼻尖手术中，为实现鼻尖的充分上旋和突出，已描述了多种缝合和移植技术。
作者描述其在鼻尖手术中采用的“三维（3D）鼻小柱支撑移植”技术。
每位患者均采用开放式鼻整形术进行治疗。作者的技术使用一种在水平面上呈特殊Y形解剖结构的3D鼻背鼻小柱支撑物。当以保持鼻间角的方式放置鼻背鼻小柱支撑物时，该技术能完美稳定经头侧穹窿缝合（CDS）塑形的下外侧软骨（LLC）。
本研究纳入了78例行3D鼻小柱支撑移植技术患者的回顾性分析。平均随访期为15个月。所有患者对其鼻尖形状均感满意。
3D鼻背鼻小柱支撑移植技术是一种易于实施且效果可靠的技术。该移植的目的是以完美的解剖对齐方式支撑重塑的LLC。对于接受鼻背降低术的患者，无需额外的软骨移植。
