To demonstrate the effects of PDO threads non-surgical rhinoplasty on patients' quality of life (using FACE-Q Scale) and first impression assessments.
This is a prospective cohort study of 10 adult patients who sought non surgical rhinoplasty to improve tip rotation or reduce the appearance of a dorsal hump. All patients fulfilled the study's enrollment criteria. Prior to treatment, patients completed pre-treatment FACE-Q surveys and pre-treatment photos were obtained. Each patient was treated with the appropriate size and number of PDO threads necessary to achieve optimal correction result (OCR). Two weeks after treatment, the patient completed posttreatment FACE-Q surveys and posttreatment photos were obtained and analyzed. First impression surveys were created using pre- and posttreatment photos, and the survey was completed by 146 blinded evaluators.
There was statistically significant improvement in the FACE-Q scores for social function (p = 0.02), psychological function (p = 0.0009) and satisfaction with nose (p = 0.0001). There was significant reduction in scores for appearance related psychosocial distress (p = 0.03). For the first impression surveys, there was a statistically significant improvement (p = 0.029) in the attractiveness scale posttreatment. Although not statistically significant, there was reduction of the dorsal hump (p = 0.15) and increase in the nasolabial angle (p = 0.48) and Goode's ratio (p = 0.16). There were no major adverse events or complications.
This study shows that the PDO threads alone can be used safely to achieve minor nasal changes especially in tip rotation and appearance of dorsal hump, to improve patients' quality of life, and perceived attractiveness of treated patients.
展示 PDO 线非手术隆鼻术对患者生活质量（使用 FACE-Q 量表）和第一印象评估的影响。
这是一项前瞻性队列研究，纳入了 10 名寻求非手术隆鼻术以改善鼻尖旋转或减少驼峰外观的成年患者。所有患者均符合研究纳入标准。在治疗前，患者完成了治疗前 FACE-Q 调查，并获得了治疗前照片。每位患者均接受了适当大小和数量的 PDO 线治疗，以达到最佳矫正效果（OCR）。治疗后 2 周，患者完成了治疗后 FACE-Q 调查，并获得了治疗后照片并进行了分析。使用治疗前后的照片创建了第一印象调查，并由 146 名盲法评估者完成了调查。
FACE-Q 量表中社交功能（p=0.02）、心理功能（p=0.0009）和对鼻子的满意度（p=0.0001）评分均有统计学显著改善。与外观相关的心理社会困扰评分显著降低（p=0.03）。对于第一印象调查，治疗后吸引力量表的评分有统计学显著改善（p=0.029）。虽然没有统计学意义，但驼峰（p=0.15）减小，鼻唇角（p=0.48）和 Goode 比值（p=0.16）增加。无重大不良事件或并发症。
本研究表明，PDO 线单独使用可安全地实现轻微的鼻部变化，特别是在鼻尖旋转和驼峰外观方面，从而改善患者的生活质量和治疗患者的感知吸引力。
