Objective To analyze the effect of the modified double-ring incision dermal brassiere technique in the correction of breast hypertrophy and ptosis. Methods A total of 50 patients with breast hypertrophy and ptosis correction admitted to the Department of Plastic Surgery, Xinjiang Vcharm Plastic Surgery Hospital from October 2023 to October 2025 were selected. According to the random number table method, they were divided into the control group and the study group, with 25 patients in each group. Both groups underwent breast reduction surgery. The control group was treated with the conventional double-ring incision dermal brassiere technique, and the study group was treated with the modiffed double-ring incision dermal brassiere technique. The operation-related indicators, treatment effect, compliance and quality of life were compared between the two groups. Results The operation time, postoperative drainage time and hospitalization time of the study group were shorter than those of the control group, and the intraoperative blood loss was lower than that of the control group (P<0.05). The total effective rate of the study group (96.00%) was higher than that of the control group (76.00%) (P<0.05). The compliance rate of the study group (100.00%) was higher than that of the control group (80.00%) (P<0.05). The QOL-30 score of the study group was higher than that of the control group (P<0.05). Conclusion The modiffed double-ring incision dermal brassiere technique has a deffnite effect in the correction of breast hypertrophy and ptosis. It can further optimize operation-related indicators, improve the total effective rate, and enhance patient compliance and quality of life.
