Abstract

Background

Preoperative assessment of breast features is indispensable for both cosmetic and reconstructive breast surgical procedures. In this study we aim to investigate the effect of breast ptosis on breast volume estimation by various methods.

Methods

Fifty patients of breast cancer planned for modified radical mastectomy were taken up. Preoperatively breast anthropometric measurement taken, grade of ptosis was noted and breast volume was calculated by anthropometry and mammography and intraopratively mastectomy specimen weight and volume was recorded. Breast volume calculated by mammography and anthropometry compared with mastectomy specimen volume and weight and correlation with ptosis was statistically analyzed.

Results

Mastectomy specimen volume showed best agreement with mastectomy specimen weight (r ​= ​.993, <.001), followed by mammographic method (r ​= ​.985, P ​< ​.001), anthropometry by breast circumference in supine method (r ​= ​.982, P ​< ​.001), anthropometry by breast circumference in upright method (r ​= ​.979, P ​< ​.001) and anthropometry by breast radius and mammary projection method (r ​= ​.969, P ​< ​.001).

Conclusion

Mammography is simple, cost effective and most accurate method for breast volume estimation followed by anthropometric breast volume calculation. As size of breast and grade of breast ptosis increases the accuracy of all methods of breast volume estimation decreases.
改良根治性乳房切除术标本的重量和体积与乳腺癌患者乳房下垂的相关性
背景乳房特征的术前评估对于乳房美容和整形手术都是不可或缺的。本研究旨在通过各种方法研究乳房下垂对乳房体积估算的影响。术前对乳房进行人体测量,记录乳房下垂的程度,并通过人体测量和乳房 X 线照相术计算乳房体积,术中记录乳房切除标本的重量和体积。结果乳房切除术标本体积与乳房切除术标本重量的一致性最好(r = .993,< .001),其次是乳房X线照相法(r = .985,P < .001)、仰卧法乳房围度人体测量法(r = .结论乳房X线照相术是简单、经济、最准确的乳房体积估算方法,其次是人体测量乳房体积计算方法。随着乳房大小和乳房下垂程度的增加,所有乳房体积估算方法的准确性都会降低。
