| Summary: | Background:. We describe our experience with bidirectional forehead narrowing and eyebrow lifting (BiNaLi), a surgical technique we have been practicing for several years to correct facial esthetic issues of patients such as long forehead, high hairline, and low eyebrow level, which helps us achieve forehead height reduction with eyebrow lifting, using 1 incision line in a one-stage procedure.
Methods:. We divided 576 patients who visited our institution between March 2014 and February 2019 into 4 groups: long forehead only (group I), low eyebrow level (groups II and IV), and M-shaped hairline (groups III and IV); BiNaLi operation was performed as appropriate for each group.
Results:. The preoperative length of the median area of the forehead was 7.3 cm, and the mean postoperative change in the length of the same was 1.4 cm. The lateral forehead length was also measured for groups III and IV. The mean preoperative length was 7.7 cm, and the mean postoperative change in the length was 1.7 cm. Eyelid length was also measured for groups II and IV. The mean preoperative length was 0.7 cm, and the mean postoperative change in the length was 0.3 cm. More than 90% of the patients gave a score of 4.0 or higher for esthetic satisfaction.
Conclusions:. We designed a BiNaLi technique to satisfy patients’ facial esthetic needs using changes in flap movement direction, adjustment in the range of skin excision, and differences in flap dissection. A single operation can have various effects, including achieving forehead shortening, clear double-fold line through eyebrow lifting, and correction of a mild M-shaped hairline.
