Background Identifying problems and making a surgical plan through a preoperative analysis is important in facial aesthetic surgery. Thus, popular conceptions of an attractive face must be analyzed beforehand. The landmarks used as reference points may change after rhinoplasty, resulting in errors in the prediction and assessment of outcomes. To reduce such errors, it is advantageous to use reference points and landmarks that are subject to minimal variation. This study measured and analyzed landmarks with little preoperative and postoperative variation in rhinoplasty, and established appropri

Although botulinum toxin is not currently Food and Drug Administration–approved for the treatment of RP, it has been used in refractory RP and has generally been found to be well tolerated. At our institution, incobotulinumtoxinA (Xeomin) and abobotulinumtoxinA (Dysport) are commonly used. Here, we report our experience with the use of incobotulinumtoxinA (Xeomin) in the hand.
