“…The following measurement methods were identified from included studies: anthropometric models [12,13], immersion in water (referred to as 'Archimedes' [12]), breast casts [12,32], the GrossmaneRoudner cone [12], computed tomography [38], magnetic resonance imaging [32,34,39], mammography [11,12,36,40,41] and 3D surface scanning [33,35,42e44].…”

“…All of these methods were assessed in a single study [12], only plaster casting [32] and anthropometric measurement [13] were assessed by other authors. The advantages of these techniques are simplicity of the approach, low-cost and ease by which they can be incorporated into a treatment pathway.…”

“…A variety of statistical measures were used to assess agreement between volume measurement methods, with differences between studies. Eight studies [11,36,38e41,43,44] reported Pearson's correlation r (Kayar et al's [12] r was calculated using intraclass correlation), six [13,32,34,35,39,42] reported coefficient of determination r 2 , seven [11,35,39e42,44] reported regression equations and three studies [39,43,44] used BlandeAltman (Table 1).

“…Of the five authors using this method, two assumed a constant density of 0.958 g/cm 3 [32,41], two didn't convert mass to volume [13,34], and one [11] used a radiologist to assess individual proportions of fat/water in the breast (based on the classification method of Stomper et al [45]), varying the density accordingly (range 0.916 g/cm 3 to 1.000 g/cm 3 ). Table 3 gives a summary of our findings from this review which is discussed in more detail below according to the specific method of measurement.…”

The accuracy of breast volume measurement methods: A systematic review

Breast volume is a key metric in breast surgery and there are a number of different methods which measure it. However, a lack of knowledge regarding a method's accuracy and comparability has made it difficult to establish a clinical standard. We have performed a systematic review of the literature to examine the various techniques for measurement of breast volume and to assess their accuracy and usefulness in clinical practice. Each of the fifteen studies we identified had more than ten live participants and assessed volume measurement accuracy using a gold-standard based on the volume, or mass, of a mastectomy specimen. Many of the studies from this review report large (>200 ml) uncertainty in breast volume and many fail to assess measurement accuracy using appropriate statistical tools. Of the methods assessed, MRI scanning consistently demonstrated the highest accuracy with three studies reporting errors lower than 10% for small (250 ml), medium (500 ml) and large (1000 ml) breasts. However, as a high-cost, non-routine assessment other methods may be more appropriate.

Breast reconstruction with autologous tissue has become an essential part of the breast cancer patient care algorithm, with the abdomen being the most common tissue donor site. However, within this field, the technology and surgical techniques available to the reconstructive breast surgeon have evolved over time. This review aims to summarize the literature surrounding current techniques in microsurgical breast reconstruction including the use of alternative, nonabdominal flaps.

The triangular prism approximation method for volume estimation of deep inferior epigastric artery perforator flap in breast reconstruction

et al. 2022

Background Many methods to predict the amount of tissue needed for breast reconstruction have been reported, but some require complicated software and special systems. The purpose of this report was to present a simpler method for predicting the volume required for deep inferior epigastric artery perforator (DIEP) flaps. The accuracy of this method was evaluated based on both actual flap design and computed tomography. Methods The weight and horizontal (x cm) and vertical (y cm) lengths of the DIEP flap were recorded, and the maximum thickness of subcutaneous tissue (z cm) was measured from computed tomography in 36 cases of breast reconstruction using DIEP flap in our hospital performed between January 2019 and December 2020. Flap volume was calculated using three methods of approximation: triangular prisms using physical and CT measurements (1/2xyz cm3); quadrangular and triangular prisms using physical and CT measurements (3/4xyz cm3); and a previously reported method using measurements from CT angiography alone and calculation with a standard mathematical formula. These three groups were compared using Bland–Altman plots and intraclass correlation coefficients (ICCs) to assess consistency between predicted and measured values. Results On Bland–Altman plots, values were distributed almost randomly around the average value of the difference, and no proportional error was evident in the methods. The ICC between predicted and actual values of triangular prisms using physical and CT measurements was largest: ICC (1, 2) = 0.978 (0.825–0.981; 95% confidence interval for ICC). A sufficient flap volume was able to be transplanted in all cases. Conclusion The methods presented appear useful to calculate flap volume closer to the measured value without complicated software systems. These results suggest that the method using two symmetric triangular prisms could predict volume more easily than previously reported methods and may facilitate good breast reconstruction.

Accuracy of the Method for Estimating Breast Volume on Three-Dimensional Simulated Magnetic Resonance Imaging Scans in Breast Reconstruction

Abstract: The authors' method for preoperatively measuring breast volume on three-dimensional simulated magnetic resonance imaging scans was both efficient and accurate. It would therefore be useful for achieving better aesthetic outcomes of breast reconstruction.
