Abstract：Objective To investigative a comparative study on the efficacy of the facial artery nasolabial groove perforator flap and the supratrochlear artery forehead flap in nasal tip defect reconstruction.Methods A total of 43 patients with nasal tip defects who underwent reconstructive surgery in our hospital from January 2024 to May 2025 were selected.Based on the surgical plan,they were di-vided into an observation group(n=23)and a control group(n=20).The observation group received repair using the facial artery nasolabial groove perforator flap,while the control group was treated with the supratrochlear artery flap.The therapeutic outcomes of both groups were observed.Results There was no statistically significant difference in surgical time,intraoperative blood loss,and postoperative drainage volume between the observation group and the control group(P>0.05).Similarly,no statistically significant difference(P>0.05)was ob-served in the nasal frontal angle,nasal facial angle,nasal tip convexity,and nasolabial angle between the observation group and the control group 6 months after surgery.The POSAS scores for the observation group were as follows:scar area,3(1～5)points;thickness,2(1～4)points;softness,2(0～3)points;pigmentation,4(2～6)points;and total score,15(8～23)points.These scores were significantly lower than those of the control group(P<0.05).The satisfaction rate of the observation group patients was higher than that of the control group(P<0.05),with a satisfaction rate of 100.00%.Conclusion Compared with the frontal trochlear artery flap,the facial artery nasolabial groove perforating branch flap has the advantages of less scarring and higher patient satisfaction in nasal tip defect plastic surgery.
