Breast asymmetry occurs when there is a discrepancy in the shape, volume, or positioning of the breasts. Various factors, including unequal development of breast buds, endocrine disorders, chest wall deformities, and surgical or posttraumatic sequelae, can contribute to this condition. Although breast asymmetry is common, clinically severe cases are rare and often require surgical correction because of potential postural, aesthetic, and psychological issues. Accurate assessment of the breast volume is crucial for planning and evaluating surgical interventions.
This prospective, non-randomized, interventional study was conducted between 2019 and 2024 at the Breast Reconstruction Section of the Federal University of São Paulo, Brazil. Forty patients with breast asymmetry were evaluated using the BREAST-V, which calculates the breast volume based on three linear measurements. Patients underwent various surgical procedures, including augmentation, reduction mammoplasty, and mastopexy, tailored to their specific type of asymmetry. Preoperative and postoperative breast volumes were compared to assess the effectiveness of surgical correction RESULTS: The study included 40 participants, with an average age of 25.2 years. The mean preoperative breast volumes were 469.6 g (right) and 448.8 g (left). The postoperative volumes decreased to 338.3 g (right) and 331.1 g (left), showing an average reduction in asymmetry of 72.9%. The minimal clinically important difference (MCID) for pre-treatment asymmetry was 65.4 g.
The BREAST-V tool has significant potential for the objective assessment of breast asymmetry. Reliable volumetric measurements can aid in surgical planning and postoperative evaluation, ultimately enhancing the clinical outcomes.

当乳房的形状、体积或位置存在差异时，就会出现乳房不对称。多种因素，包括乳腺芽发育不均、内分泌失调、胸壁畸形以及手术或创伤后后遗症，都可能导致这种情况。尽管乳房不对称很常见，但临床上严重的病例很少见，由于潜在的姿势、美学和心理问题，通常需要手术矫正。准确评估乳房体积对于规划和评估手术干预至关重要。
这项前瞻性、非随机、干预性研究于2019年至2024年在巴西圣保罗联邦大学乳房重建科进行。对40例乳房不对称患者使用BREAST-V进行评估，该工具基于三个线性测量值计算乳房体积。患者接受了各种手术，包括隆乳术、乳房缩小术和乳房上提术，这些手术是根据他们特定的不对称类型量身定制的。比较术前和术后的乳房体积，以评估手术矫正的效果。结果：该研究包括40名参与者，平均年龄为25.2岁。术前右乳平均体积为469.6克，左乳为448.8克。术后体积降至右乳338.3克，左乳331.1克，不对称平均减少72.9%。治疗前不对称的最小临床重要差异（MCID）为65.4克。
BREAST-V工具在客观评估乳房不对称方面具有巨大潜力。可靠的体积测量有助于手术规划和术后评估，最终改善临床结果。
