Reply: Effects of Botulinum Toxin on Improving Facial Surgical Scars: A Prospective, Split-Scar, Double-Blind, Randomized Controlled Trial Sir: Thank you and your colleagues for your interest in our article and also for your insightful comments. We completely agree that the different tensions can lead to different aesthetic outcomes in scars. The expanded flap in Figure 1 was successful, with no necrosis. During surgery, tension was controlled by adjusting the position of the eyebrows. The patient had symmetrical brows before the procedure and at 6-month follow-up (Fig. 1). The symmetrical eyebrows demonstrated that there was no difference between the tension of the treated half and the control half. A total of 14 patients with 19 facial surgical scars were included in our study. Among these, seven longitudinal scars located on the forehead were divided randomly into upper or lower parts. The lower forehead might differ from the upper for the presence of transverse tension applied by the corrugators. However, in our study, the results showed no statistical difference in visual analogue scale score and width of scars between the aesthetic outcome of the upper and lower parts, regardless of which side had been treated with botulinum toxin type A (Table 1). This suggests that the corrugators might not Necmettin Erbakan University School of the Medicine Konya, Turkey
