Caucasians usually have reduction or correction rhinoplasty; however, Asian nasal surgery is mainly for augmentation rhinoplasty. Therefore, an Asian rhinoplasty should start with a precise understanding of ethnic anatomical differences. The authors summarize the anatomical characteristics of Asians to ensure the best results.

Asian rhinoplasty patients can be analyzed by the nose's component structures and their relationship to one another. A comprehensive understanding of the underlying anatomical structure including bone, cartilage, and soft tissue contributes to better preoperative planning. To achieve an optimal postoperative result, a thorough preoperative analysis utilizing standardized measurements is essential. Knowledge of the Asian nose facilitates the use of an algorithmic approach to Asian rhinoplasty that increases surgical predictability.

To optimize the outcome of BoNT injection, we recommended injecting into six points separated by 2 cm in sections b and c of the upper trapezius muscle. It is significant that it is easier to apply to anyone than to apply unstructured techniques.
