双环形切口巨乳缩小术腺体切除量预估模型

Prediction Formula for Intraoperative Resection Weights of Reduction Mammoplasty with Double-circle Periareolar Incision

摘要

摘要:
目的建立双环形切口巨乳缩小术腺体切除量的预估模型。
方法回顾性收集78例患者的133侧双环形切口巨乳缩小术的相关资料, 包括术前测量的患者双侧锁乳距、胸乳距、乳房内径、乳房下径、乳房外径数据(cm), 及术中精确测量的每侧切除的乳腺腺体重量(g)。对数据进行统计学分析, 利用多元逐步回归得出术前乳房的测量数据与术中切除乳腺腺体量的关系。
结果双环形切口巨乳缩小术中乳腺腺体切除量的计算公式为:乳腺腺体切除量=32×锁乳距+31×乳房下径+8×乳房内径-986, 或乳腺腺体切除量=25×胸乳距+32×乳房下径+13×乳房内径-868。
结论该公式为双环形切口巨乳缩小术腺体切除量的经验性总结, 应用该公式有助于术前估算, 指导术中乳腺腺体切除量, 以及维持术后双侧乳房的对称性。

Abstract:
Objective To derive a formula for predicting intraoperative resection weights of reduction mammoplasty with double-circle periareolar incision.
Methods Data were collected from 78 consecutive patients receiving reduction mammoplasty with double-circle periareolar incision (133 sides) between 2003 and 2015, including preoperative bilateral clavicle-to-nipple distance, sternal notch-to-nipple distance, nipple-to-ipsilateral costoclavicular line distance, nipple-to-inframammary crease distance, nipple-to-anterior axillary line distance(cm), and resected weight (g) on each side of breast measured during the surgery. Multiple stepwise regression analysis was performed to establish the relationship between preoperative measurements and the resection weight.
Results Formulas were established as follows:resected weight=(32×clavicle-to-nipple distance+31×nipple-to-inframammary crease distance+8×nipple-to-ipsilateral costoclavicular line distance)-986, or resected weight=(25×sternal notch-to-nipple distance+32×nipple-to-inframammary crease distance+13×nipple-to-ipsilateral costoclavicular line distance)-868.
Conclusion This formula summarizes the experience of reduction mammoplasty with double-circle periareolar incision, which could guide the surgeon in preoperative estimation, intraoperative resection, and postoperative maintenance of breast symmetry.
