Abstract: Objective To explore the effect of circumareolar incision surgery on surgical indexes and sensory nerve function of the areola region in patients with breast fibroma. Methods A total of 80 patients with mammary fibroma were randomly divided into control group and observation group, with 40 cases in each group. The control group was treated with radial incision surgery, while the observation group was treated with circumareolar incision surgery. The operative indicators, sensory nerve function in the areola area and scar healing were compared between the two groups. Results The operative time and scar length of the observation group were significantly shorter than those in the control group, and the intraoperative blood loss was significantly less than that in the control group(P<0.05). The primary healing rate of postoperative wound and basic symmetry rate of bilateral breasts in the observation group were significantly higher than those in the control group(P<0.05). The nerve function in the areola area of the observation group at 1 day and 6 months after operation was significantly better than that of the control group(P<0.05). The scar healing scores of the observation group at 2, 4 and 6 months after operation were significantly lower than those of the control group(P<0.05). Conclusion Ring-areola incision in the treatment of mammary fibroma has better efficacy than that of radial incision, which has good aesthetics and can reduce the damage of sensory nerve function in the areola area.
