摘要目的:探讨一体式假体在隆眉弓的效果和优势。方法:2019年6月至2020年10月，成都高新心悦容医疗美容门诊部收治眉弓眉心低平女性患者45例，年龄20~39岁，平均29.8岁，初次手术43例、修复2例。根据患者眉弓眉心形态雕刻膨体个性化一体式眉弓，切口设计在双侧眉下缘中外侧，在额骨骨膜下剥离腔隙，两侧连通汇合于眉心及眉心倒三角区域，将雕刻的假体从一侧植入，另一侧拉出，将假体捋平。对术后并发症、切口瘢痕、外观形态、整体满意度进行评估。结果:45例患者切口均一期愈合，切口瘢痕隐蔽。随访6~18个月，4例术后出现轻微头皮麻木，3个月后恢复正常；1例术后3个月出现眉心部位假体显形，经调整后恢复正常。45例患者双侧眉弓对称性、弧度、饱满度、凸度、触感效果非常满意39例，占86.7%；满意6例，占13.3%。术前侧面角膜到眉弓最凸点距离(2.02±1.72) mm，术后末次随访侧面角膜到眉弓最凸点距离(6.5±1.19) mm，差异有统计学意义( t＝14.49， P<0.01)。 结论:一体式假体隆眉弓手术方法安全有效、操作简便，可明显增加眉弓眉心区域的骨性美感和立体感，是隆眉弓的理想方法之一。

abstractsObjective:To explore the feasibility and advantages of integrated prosthesis of expanded polytetra-fluoroethylene (e-PTFE) in eyebrow arch augmentation.Methods:The clinical data of 45 patients with low or flat brow arch and glabellar zone from June 2019 to October 2020 in Chengdu High-tech Zone Xinyuerong Medical Aesthetic Clinic were analyzed retrospectively, in which it included 45 women, whose ages ranged from 20 to 39 years with average 29.8 years. Forty-three cases underwent primary surgery, and 2 cases underwent repair. The e-PTFE was sculpted to be personalized integrated prosthesis according to the shape of the patient's eyebrow arch and glabellar zone. The incision was designed on the medial and lateral sides of the lower margin of the bilateral eyebrow to avoid the supraorbital foramen, and the lacunae were striped under the frontal periosteum, and the two sides were connected to cover the glabellar zone and inverted triangle area between the eyebrows. The carved e-PTFE was implanted into one side and pulled out from the other side. The prosthesis was smoothed by Venn pliers of the ventral and dorsal sides.Results:The 45 patients in this group were followed up for 6-18 months. The incisions of all the patients were healed Ⅰ/A, and the scar of the incisions was concealed. Slight scalp numbness occurred in 4 patients and returned to normal 3 months later. The prosthesis in the glabellar zone appeared in 1 case 3 months after operation and returned to normal after reoperation. The symmetry, radian, fullness, convexity and tactility of bilateral eyebrow arch were all satisfactory in 45 cases. 39 cases were very satisfied, accounting for 86.7%; 6 cases (13.3%) were satisfactory. The sagittal distance of the anterior surface of the cornea to the soft tissues overlying the supraorbital rims was (2.02±1.72) mm preoperatively and (6.5±1.19) mm in the last follow-up. The difference was statistically significant ( t=14.49, P<0.01). Conclusions:This design of integral e-PTFE in eyebrow arch augmentation is safe, effective and easy to operate. It can significantly increase the bony beauty and stereoscopic sense of the eyebrow arch and glabellar zone, effectively deepen the eye socket, improve the eye protrusion, and reduce the risk of asymmetry and prosthesis displacement, and therefore it is one of the ideal methods for eyebrow arch augmentation.
