Abstract
The Endotine Forehead device (Coapt Systems, Inc., Palo Alto, Calif.) is an implantable bioabsorbable fixation device designed to provide intuitive, multipoint, distributed tension and repeatable and predictable brow fixation during endoscopic and open browplasty. The purpose of this study was to evaluate early results in a series of endoscopic brow lift cases using the Endotine Forehead device. Two versions of the Endotine device were used in this study. One was composed of polylactic acid, and the other was a smaller version consisting of 82/18 L-lactide/glycolide). In a consecutive series of endoscopic brow lift cases, preoperative and postoperative standardized photographs were taken in the Frankfort horizontal plane and three measurements were compared: midpupil to superior brow, midpupil to hairline, and lateral canthus to superior brow. A total of 21 patients (19 women and two men) underwent endoscopic browplasty. Photographs were obtained preoperatively and 54 to 174 days postoperatively. Brow elevation measurements were obtained postoperatively. No significant adverse events were encountered in the follow-up period. The Endotine Forehead device provides significant and reproducible brow elevation, with no significant adverse events, as measured at three points in excess of 14 weeks postoperatively.
