Preoperative planning of breast implants using the breast implant planning device (BIPD)

Interstitial implantation of the tumor excision site is an important component of the treatment program of breast-conserving surgery and irradiation. The currently accepted method of designing and performing the implant in the operating room does not assure adequate coverage of the volume of tissue at risk, i.e., the tissue immediately adjacent to the walls of the original tumor excision cavity. This communication describes a technique of preoperative implant planning that consistently and reliably ensures adequate coverage of the volume of tissue at risk. An integral part of this technique is the use of a new device called the Breast Implant Planning Device. This device is a modification of previously described implant template devices.
