Brow ptosis is the main consequence of aging in the upper third of the face. Many methods have been described to correct it: skin excisions of the brow hairline, skin excisions of the forehead natural creases, skin trimmings of the temporal, coronal, or forehead hairline flaps, and endoscopic methods [1,15,17,18,24,26,27]. The authors created a procedure which is based on a forehead-temporal subcutaneous flap and a muscular relocation. It treats the brow ptosis and its surrounding area-temporal ptosis, upper and lower lateral eyelid ptosis, crow's feet-and at the same time improves the sclera show or ectropion. The method preserves the sideburn and the temporal hairline and can reduce the width between the temporal hairline and the lateral end of the eyebrow. The method produces maximum improvement, with high-quality scars and minimal evidence of surgery. The procedure is called "The Toucan Technique," due to the shape of the skin resection which looks like a toucan bird [11,13,14].
眉下垂是面部上三分之一区域衰老的主要表现。已有多种方法用于矫正眉下垂：眉发际线皮肤切除术、前额自然皱纹皮肤切除术、颞部、冠状或前额发际线皮瓣皮肤修整术以及内镜手术方法[1,15,17,18,24,26,27]。作者设计了一种基于额颞皮下皮瓣和肌肉重新定位的手术方法。该方法可治疗眉下垂及其周围区域——颞部下垂、上下睑外侧下垂、鱼尾纹——同时改善巩膜外露或眼睑外翻。该方法保留了鬓角和颞部发际线，并可缩小颞部发际线与眉外侧端之间的宽度。该方法能产生最大程度的改善效果，瘢痕质量高且手术痕迹不明显。由于皮肤切除形状类似巨嘴鸟，该手术被称为“巨嘴鸟技术”[11,13,14]。
