ObjectiveTo explore the effectiveness of liposuction technique assisted superomedial pedicle with a vertical incision in reduction mammaplasty.MethodsBetween March 2014 and March 2019, 65 patients (127 sides) with breast hypertrophy had undergone breast reduction by using liposuction technique assisted superomedial pedicle with a vertical incision. The patients were 21 to 58 years old, with an average of 42.2 years. Body mass index ranged from 18.8 to 26.5 kg/m2, with an average of 21.3 kg/m2. Among them, 62 cases were bilateral operations and 3 cases were unilateral operation. The degree of mastoptosis was rated as degreeⅡ in 73 sides and degree Ⅲ in 54 sides according to the Regnault criteria.ResultsThe unilateral breast removed 432 g on average (range, 228-932 g); the distance of nipple upward was 4.5-9.5 cm (mean, 6.5 cm); the volume of unilateral liposuction was 50-380 mL (mean, 148 mL). There were 2 sides (1.58%) of unilateral intramammary hematomas after operation, 4 sides (3.15%) of bilateral breast vertical incisions slightly split, and 1 side (0.79%) of the nipple-areola epidermis necrosis. All patients were followed up 6 months to 5 years, with an average of 18 months. During the follow-up, there was no evident re-dropping of the breast and no enlargement of the areola. No patient underwent scar excision. At last follow-up, the effectiveness was evaluated by the surgeons. There were 52 cases with very satisfactory, 10 cases with satisfactory, and 3 cases with unsatisfactory for the breast shape and symmetry. There were 51 cases with very satisfactory, 11 cases with satisfactory, and 3 cases with unsatisfactory for the nipple position and areola diameter. The incision scar was obvious in 25 cases and was not obvious in 40 cases. The results of self-assessment showed very satisfactory for the breast shape in 48 cases, satisfactory in 12 cases, and unsatisfactory in 5 cases; very satisfactory for the incision scar in 40 cases, satisfactory in 17 cases, and unsatisfactory in 8 cases. Overall evaluation of the patient was very satisfactory in 52 cases, satisfactory in 7 cases, and unsatisfactory in 6 cases.ConclusionThe liposuction technique assisted superomedial pedicle with a vertical incision in reduction mammaplasty is a safe and reliable surgical method with a satisfactory result.
