Pilot Study: Thread Rhinoplasty With Different Methods of Barbed Thread Implantation.

[BACKGROUND] 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).

[METHODS] 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.

[RESULTS] 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).

[CONCLUSIONS] 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.
