Thread rhinoplasty is a minimally invasive procedure with short downtime and high patient satisfaction. Although it is known that the effectiveness of rhinoplasty varies depending on the method of thread placement, there have been no studies quantifying these differences. In this study, we analyzed the differences in the effectiveness of rhinoplasty depending on the method of thread implantation using a 3-dimensional imaging analyzer (VECTRA H2, Canfield Scientific).
This study was a prospective observation study. Six patients who underwent rhinoplasty using threads from February to May 2024 were divided into 2 groups according to the method of thread placement: nasal septum implantation group (group S) and nasal septum + nasal dorsum implantation group (group SD). The pre- and postoperative changes analyzed by VECTRAH2 were compared between the 2 groups.
Nasal dorsal length change, nasal wing length change, and nasal wing length/nasal dorsal length ratio change were not significantly different between the two groups. The angular changes were as follows: nasolabial angle change (15 [8-23], -1 [-7 to 6], < 0.05), nasal frontal angle change (-3 [-4 to -2], 1.67 [1-3], < 0.05), nasal face angle change (4 [3-5], 1 [0-2], < 0.05), and nasal jaw angle change (-4.3 [-5 to -3], -4.3 [-5 to -4], > 0.05).
Thread rhinoplasty was found to have different postoperative effects depending on the method of thread implantation. It was suggested that it is possible to provide a procedure that meets the patient's wishes.
线雕隆鼻术是一种微创手术，恢复时间短，患者满意度高。虽然已知隆鼻术的效果因线体植入方法而异，但尚无研究对这些差异进行量化。在本研究中，我们使用三维成像分析仪（VECTRA H2，Canfield Scientific）分析了根据线体植入方法不同而导致的隆鼻术效果差异。
本研究为前瞻性观察研究。2024年2月至5月接受线雕隆鼻术的6例患者根据线体植入方法分为2组：鼻中隔植入组（S组）和鼻中隔+鼻背植入组（SD组）。比较两组通过VECTRA H2分析的术前和术后变化。
两组之间鼻背长度变化、鼻翼长度变化和鼻翼长度/鼻背长度比值变化无显著差异。角度变化如下：鼻唇角变化（15[8 - 23]，-1[-7至6]，<0.05），鼻额角变化（-3[-4至-2]，1.67[1 - 3]，<0.05），鼻面角变化（4[3 - 5]，1[0 - 2]，<0.05），鼻颌角变化（-4.3[-5至-3]，-4.3[-5至-4]，>0.05）。
发现线雕隆鼻术根据线体植入方法不同术后效果不同。提示有可能提供一种符合患者意愿的手术方法。
