The endotine: A new biodegradable fixation device for endoscopic forehead lifts

Abstract

Background: No single technique for fixation of the scalp after endoscopic forehead lift is universally accepted, and complications such as alopecia and regression of elevation have been reported with all techniques. Objective: This report describes the preliminary results of a study of the Endotine 3.5 forehead device (Coapt Systems, Inc, Palo Alto, CA), a new biodegradable fixation device. Methods: The Endotine 3.5 device consists of a post on the deep side for anchoring it in the skull and five tines on the superior side for engaging the deep scalp tissues. It was tested in 9 patients, with postoperative follow-up ranging from 6 to 8 months. The surgeon evaluated the device for difficulty/ease of use, palpability, postsurgical pain, and wound healing. Results: The Endotine 3.5 device produced a secure fixation without problems or complications, although it was often palpable with moderate degrees of sensitivity. It could be applied in less than 2 minutes per side. Conclusions: Our preliminary findings indicate that the Endotine 3.5 forehead device provides rapid, secure fixation without the complications associated with other fixation techniques. After patients reported that it was still palpable up to 24 weeks after implantation, a second-generation polymer that dissolves more rapidly was fabricated. Further studies are under way to evaluate long-term efficacy.
