Forehead Reduction Surgery via an Anterior Hairline Pretrichial Incision in Asians: A Review of 641 Cases.

Background Forehead reduction is gaining in popularity, as facial proportions that include shorter upper and lower thirds are currently more aesthetically pleasing. In this first large-scale study, we present an analysis of several important aspects of surgical design and postoperative complications associated with forehead reduction performed via a pretrichial skin excision. Methods Patients who underwent surgery from 2006 to 2018 were reviewed retrospectively. Data included the amount of skin excised, postoperative complications experienced during the first three months, and forehead length measured 2 years postoperatively. Objective outcomes reported by three independent surgeons and subjective satisfaction reported by patients at three months postoperatively were evaluated on 5-point Likert scales that addressed both postoperative scarring and overall aesthetics. Results A total of 641 patients underwent forehead reduction surgery. The average lengths of the skin excisions were 16.64 mm, 15.36 mm, and 15.33 mm from regions at the center and at the left and right mid-pupillary lines, respectively. Long-term follow-up of 85 patients revealed forehead lengthening that exceeded the initial postoperative measurements by 2.44 mm (15.04%), 1.98 mm (11.53%), and 2.51 mm (15.8%) at the left, center, and right, respectively. Means (standard deviation [SD]) for subjective and objective measures of postoperative scarring were 1.32 (0.49) and 1.78 (0.66), respectively. The means (SD) for subjective and objective postoperative aesthetic scores were 4.38 (0.47) and 3.98 (0.39), respectively. Conclusions Forehead reduction surgery via a pretrichial skin excision is a straightforward procedure that is easy to perform, has few complications, and result in high rates of patient satisfaction.
