[Computer planning for postmastectomy breast reconstruction by tissue expansion]

Aim of this paper is to present a computer program able to provide objective and quantitative data useful to guarantee the selection of the proper implant in order to obtain symmetry with the contralateral breast, in case of unilateral breast reconstruction by tissue expansion, especially for surgeons without experience or for occasional operators. Our C++ program provides the final implant volume using the measurements of the semi-circumference and projection of the contralateral breast performed on the supine patient. The aim is the symmetry of the two breasts. According to personal experience in breast reconstruction by tissue expanders, this program allows non invasive and simple measurements of the breast volume, useful to obtain the mammary symmetry. In case of breast reconstruction by tissue expansion, the preoperative evaluation is usually based on the surgeon experience and on the empirical observation without knowing the correct volume to reach. Since this program is useful to know the precise necessary volume for breast reconstruction, it allows the surgeon to obtain a better plastic result.
