More precise treatment is possible by dividing the depressed area of the upper eyelid according to the stage. Satisfactory results were achieved by relocating the orbital fat using an open method and adjusting the ROOF fat graft according to the stage.

The main advantage of this surgical technique is preserving continuity of the orbicularis oculi muscle while selectively decreasing muscle tone. Hence, this technique may prevent any contour irregularities. The RF current causes irreversible muscle fibrosis, which in turn provides long-lasting results. While the early results of this series show promising long-term efficacy and a good safety profile, the small number of patients and short-term follow-up period warrant further study.

Background The frontalis sling procedure is a useful approach for correcting severe blepharoptosis. However, blepharoptosis often recurs after corrective surgery using the tensor fascia lata. Good results without recurrence after a modified Fox method were obtained using the palmaris longus tendon. This study examined the safety and validity of the surgical method using the palmaris longus tendon through long-term follow-up observations. Methods To reduce the rate of recurrence, the highest point on the pentagon of the Fox method was fixed to the frontalis fascia and frontalis muscle. It was fixed once again to the area 1 cm above the highest point. This approach remarkably reduces the incidence of recurrence by fixing the pentagon of the Fox method not only to the palmaris longus tendon but also to the frontalis fascia and again to the frontalis muscle. A modified Fox method using the palmaris longus tendon was used to treat 16 eyelids of 10 patients. A senior surgeon performed the procedure in all cases under local anesthesia. Results The mean follow-up period was 51 months (range = 18-86 months). There was no case of blepharoptosis recurrence and a good field of view was secured after surgery. Long-term follow-up revealed that the visual field had been well secured with a mean MRD1 of 3

Background: The efficacy and safety of equine cartilage as a competent xenograft material for rhinoplasty were evaluated and compared to the outcomes of rhinoplasty using silicone implants.Methods: We performed a multicenter, double-blind, non-inferiority, and randomized confirmatory study. Fifty-six patients were randomized 1:1 to the study group (using MegaCartilage-E) and control group (using silicone implants). The Rhinoplasty Outcome Evaluation (ROE) score, photo documentation, Global Aesthetic Improvement Scale (GAIS), and adverse event data were obtained until 12 months after surgery. The primary efficacy, which is the change in ROE score 6 months after surgery, was assessed in the modified intention-to-treat set. The secondary efficacy was evaluated in the per-protocol set by assessing the change in ROE score 6 and 12 months after surgery and nasofrontal angle, the height of the nasion, and GAIS 1, 6, and 12 months after surgery.Results: The change in ROE score of the study group was non-inferior to that of the control group; it increased by 24.26 ± 17.24 in the study group and 18.27 ± 17.60 in the control group (<i>p</i> = 0.213). In both groups, all secondary outcome measures increased, but there was no statistical difference. In the safety set, treatment-emergent adverse events occurred in 10 patients (35.71%) in the study group and six patients (21.43%) in the control group (<i>p</i> = 0.237). There were 13 adverse device events in the study group and six adverse device events in the control group (<i>p</i> = 0.515).Conclusion: Processed equine cartilage can be used effectively and safely as xenograft material for rhinoplasty.
