Objective To analyze the effect of the alar contour grafts on the postoperative alar retraction in rhinoplasty. Methods Forty female patients attending the author’s hospital for first time rhinoplasty from December 2018 to December 2020 were selected. A random number table method was used to divide the group into the experimental group and the control group of 20cases each. In the experimental group, the alar grafts were routinely placed, while in the control group, the alar grafts were not used. The long axis of the nostrils and the distance between the highest point of the alar rim and the long axis of the nostrils were observed by taking a lateral view photograph of the patient to evaluate the relationship between the columella and the alar rim. In comparison of patients’ nostril axis ratios preoperatively and one year postoperatively. Results Post-operative follow-up one year and 12 cases were lost to follow up. There were 15 cases in the final experimental group and 13 cases in the control group. The difference between the preoperative nostril axis ratio of the experimental group and the control group was not statistically significant（P＞0.05）.The postoperative nostril axis ratio of the experimental group was smaller than that of the control group, and the difference was statistically significant. The difference between the preoperative and postoperative nostril axis ratio in the experimental group was not statistically significant（P＞0.05）.In the control group, there was a statistically significant difference between the preoperative and postoperative nostril axis ratios（P＜0.01）.There were no post-operative complications in two groups. Conclusion General applications of the alar contour grafts in rhinoplasty could significantly prevent the alar retraction postoperation.
