RESUMEN
Objective: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.
RESUMEN
Objective:To investigate the effect of eyebrow arch augmentation with personalized polyether ether ketone (PEEK) implant assisted by endoscope.Methods:From January 2019 to August 2021, 9 patients with low and flat eyebrow arch requiring eyebrow arch augmentation were treated in the plastic surgery department of the Friendship Plastic Surgery Hospital Affiliated to Nanjing Medical University. The cranial and maxillofacial CT scanning data were obtained before operation, the eyebrow arch elevation range and height were designed according to the patient's requirements, and personalized peek implants were manufactured. During the operation, a small temporal hairline incision was used to accurately separate the implantation cavity of individualized peek implants under the periosteum of the eyebrow arch implantation area with the aid of endoscope. Personalized PEEK implants were implanted under endoscope to make them fully fit with the eyebrow arch bone and fixed with titanium nails. Photos were taken and analyzed before and after operation.Results:All patients were followed up for 3 months to 2 years. Their facial expressions were normal, and there were no motor nerve injury, rejection and iatrogenic infection. The patients were satisfied with the postoperative effect. Compared with before operation, the low level of orbital bone in eyebrow area was improved, and the facial contour was three-dimensional and harmonious.Conclusions:The eyebrow arch augmentation with individualized peek implant assisted by endoscope is safe and effective. It can greatly reshape the upper contour of the face, deepen the upper eyelid fossa and improve the convex eye phenomenon, so as to achieve the cosmetic effect of enhancing the three-dimensional sense of the eyebrow orbital area, which is worthy of clinical application.
