Preoperative Assessment Tool for the Planning of Inframammary Incision and Implant Profile in Breast Augmentation

When using the inframammary access incision for breast augmentation, careful planning is critical to allow the surgeon to set the inframammary fold (IMF) at the most optimal position, minimize scar visibility, and mitigate the main disadvantage of this approach. Current popular evaluation systems for breast augmentation include the High Five and Randquist systems and they base their calculations on inconsistent variables like skin stretch measurements. We propose a simple method that is not dependent on skin stretch measurements to properly determine implant size, profile, and position of the inframammary fold. Excluding digital scans and computer-based systems that are not universally available, the proposed simplified assessment tool was compared to the two most popular manual measuring tools (High Five and Randquist). Twenty-five female volunteers were included in the study. The projected IMF positions over the midsternal line for each measuring tool were recorded on each patient and the sternal notch (SN) to projected IMF distance SN–IMF₁ (simplified evaluation system), SN–IMF₂ (High Five System), and SN–IMF₃ (Randquist system) were compared. The anticipated new IMF position is determined based on the vertical implant dimension and not on breast base width. For most subjects, the differences between the three evaluation systems were minimal. The proposed breast measurement tool constitutes a new, much simpler, and practical method that proved to be successful in our hands.
