Measurement of changes in forehead height after endoscopic forehead lift

Endoscopic forehead lift is a procedure used for upper face rejuvenation and to correct brow ptosis effectively. This procedure is less invasive than classic forehead lift, and complications such as a long scar on the scalp, paresthesia, and alopecia occur less frequently. Therefore, endoscopic procedures are often substituted for procedures involving a coronal incision [1]. Many studies have investigated the effects of endoscopic forehead lift in terms of eyebrow morphology, aesthetics, longevity, and complications [2-5]. Forehead lift primarily raises the eyebrows and helps to flatten the skin of the forehead and temporal region. This subsequently complements the asymmetry of both eyebrows and elongates the upper third of the face due to modifications of the muscles of facial expression in the upper facial area and hairline elevation [1]. Studies analyzing the outcomes of endoscopic forehead lift in terms of external appearance have generally focused on changes in the shape and position of the eyebrows. In contrast, studies on variations in the height of the hairline are very rare [6], and it is difficult to find exact references regarding the extent of forehead elongation after a Jae Min Chung, Won Ki Kang, Jeong Su Shim
