Abstract

Background: Three-dimensional (3D) printing technology is actively applied in rhinoplasty procedures. The use of 3D-printed silicone implants facilitates success in surgery, even when the surgeon lacks experience. However, in some cases, deviation or displacement of 3D-printed silicone implants can occur even without postoperative septal and tip deviation.

Objective: This study aimed to explore factors influencing the deviation of 3D-printed silicone implants.

Methods: We identified 293 patients (55 males, 238 females) who underwent rhinoplasty and retrospectively reviewed their operative records and facial computed tomography images. The incidence of deviation when using 3D-printed silicone implants was investigated. Various factors influencing the deviation of 3D-printed silicone implants were examined. The contact area was calculated using a 3D surface meshing approach.

Results: Deviation of 3D-printed silicone implants occurred in 23.55% of patients (females, 23.53%; males, 23.64%), with nine (3.07%) undergoing revision surgery due to complaints about postoperative nose deformity caused by this deviation. Among variables studied in the male and female groups, only the contact area between the nasal bone and 3D-printed silicone implant was a significant factor in determining deviation. The optimal cutoff values of the contact area in the male and female groups were 295.71 mm² and 256.58 mm², respectively. The average cutoff values of the contact area differed between the no-deviation and deviation groups but were similar among the mild, moderate, and severe deviation groups.

Conclusion: The contact area between the nasal bone and 3D-printed silicone implant is a predictive factor for implant deviation in rhinoplasty procedures using 3D-printed silicone implants.

3d打印硅胶植入物与鼻骨的接触面积作为植入物偏差的预测因素。

背景：三维（3D）打印技术在鼻整形手术中得到了积极的应用。使用3d打印硅胶植入物有助于手术成功，即使外科医生缺乏经验。然而，在某些情况下，即使没有术后鼻中隔和鼻尖偏差，3d打印硅胶植入物也会发生偏差或移位。目的：探讨影响3d打印硅胶植入体偏差的因素。方法：我们选取了293例鼻整形患者（男性55例，女性238例），并回顾了他们的手术记录和面部计算机断层图像。研究了使用3d打印硅胶植入物时的偏差发生率。研究了影响3d打印硅胶植入物偏差的各种因素。采用三维曲面网格法计算接触面积。结果：23.55%的患者出现3d打印硅胶植入物偏差(女性23.53%；男性占23.64%)，其中9例（3.07%）因鼻偏位导致术后鼻畸形而接受翻修手术。在男性和女性组研究的变量中，只有鼻骨与3d打印硅胶植入物之间的接触面积是决定偏差的重要因素。男性和女性接触面积的最佳临界值分别为295.71 mm2和256.58 mm2。无偏差组和偏差组接触面积的平均截止值不同，但轻度、中度和严重偏差组的接触面积平均截止值相似。结论：鼻骨与3d打印硅胶假体的接触面积是3d打印硅胶假体隆鼻手术中假体偏离的预测因素。证据等级iii：本刊要求作者为每篇文章指定证据等级。有关这些循证医学评级的完整描述，请参阅目录或在线作者说明www.springer.com/00266。

期刊介绍： Aesthetic Plastic Surgery is a publication of the International Society of Aesthetic Plastic Surgery and the official journal of the European Association of Societies of Aesthetic Plastic Surgery (EASAPS), Società Italiana di Chirurgia Plastica Ricostruttiva ed Estetica (SICPRE), Vereinigung der Deutschen Aesthetisch Plastischen Chirurgen (VDAPC), the Romanian Aesthetic Surgery Society (RASS), Asociación Española de Cirugía Estética Plástica (AECEP), La Sociedad Argentina de Cirugía Plástica, Estética y Reparadora (SACPER), the Rhinoplasty Society of Europe (RSE), the Iranian Society of Plastic and Aesthetic Surgeons (ISPAS), the Singapore Association of Plastic Surgeons (SAPS), the Australasian Society of Aesthetic Plastic Surgeons (ASAPS), the Egyptian Society of Plastic and Reconstructive Surgeons (ESPRS), and the Sociedad Chilena de Cirugía Plástica, Reconstructiva y Estética (SCCP). Aesthetic Plastic Surgery provides a forum for original articles advancing the art of aesthetic plastic surgery. Many describe surgical craftsmanship; others deal with complications in surgical procedures and methods by which to treat or avoid them. Coverage includes "second thoughts" on established techniques, which might be abandoned, modified, or improved. Also included are case histories; improvements in surgical instruments, pharmaceuticals, and operating room equipment; and discussions of problems such as the role of psychosocial factors in the doctor-patient and the patient-public interrelationships. Aesthetic Plastic Surgery is covered in Current Contents/Clinical Medicine, SciSearch, Research Alert, Index Medicus-Medline, and Excerpta Medica/Embase.
