Endoscopic Forehead Lifting with a Novel Polymer Fixation Peg: A Case Series and Narrative Review

This study evaluates a novel high-density polyethylene (HDPE) browlift peg for brow fixation in endoscopic forehead lifting, assessing its safety, effectiveness, and aesthetic outcomes while contextualizing its use through a narrative review of existing techniques. Twenty-nine consecutive female patients underwent bilateral endoscopic brow lifts using a custom-shaped HDPE peg inserted into the frontal bone via a small paramedian incision. Outcomes included postoperative brow symmetry, defined as ≤2 mm asymmetry, and documentation of complications. The mean patient age was 62.1 years, with an average follow-up of 12.3 months. All patients achieved symmetric brow positioning within 2 mm. No cases of implant extrusion, wound dehiscence, or permanent nerve injury occurred. Minor complications included one case each of transient paresthesia, localized incision infection not involving the implant, and a palpable implant removed in-office under local anesthesia. A parallel narrative review highlighted common limitations in brow fixation strategies—namely, implant palpability, risk of relapse, cost, and invasiveness. These findings suggest that the HDPE peg is a safe, customizable, and cost-effective alternative for brow fixation, offering durable aesthetic results with minimal complications and potential value in aesthetic and oculoplastic surgery.
