PurposeTo investigate the effectiveness of hairline advancement in treating patients with perceived close-set eyes due to a wide infratemple area.Materials and MethodsInfratemple area hairline advancement was performed in 19 patients with perceived close-set eyes caused by a wide infratemple area; all were women with a mean age of 29.4 years.ResultsThe wide infratemple area was effectively narrowed in the frontal view in all patients. The mean reduction in the distance between the bilateral infratemple hairlines in the frontal view was 5.2 mm (range 3.9–6.3 mm). The appearance of close-set eyes was ameliorated, and patient satisfaction was high. No side effects, such as asymmetry or wound infection, were encountered.ConclusionHairline advancement surgery appears to be a safe and effective means of treating patients with perceived close-set eyes due to a wide infratemple area.Level of Evidence IVThis journal requires that authors assign a level of evidence to each article.
