Novel 3-Dimensional Imaging Analysis of the Ryan Procedure for Inframammary Fold Elevation in the Reconstruction of the Revised Breast.

Abstract

Summary:The inframammary fold (IMF) can be challenging to reconstruct after disruption during mastectomy or breast reconstruction. The Ryan procedure is a previously described technique with little long-term analysis. Our goal is to analyze the long-term results of the Ryan procedure using 3-dimensional (3D) technology, with the hypothesis that 3D measurements will provide quantitative outcomes that add to the qualitative assessment of the reconstruction. We retrospectively reviewed consecutive breast reconstruction patients by a single surgeon from January 1, 2012 to January 31, 2015 to identify patients who underwent the Ryan procedure. Previously obtained 3D photographs were then analyzed to compare breast base diameter, breast projection, and inter-IMF distance pre- and postoperatively. A survey was then given to 15 health professionals in our department to assess the IMF and symmetry pre- and postoperatively. Eight patients were eligible for inclusion. Four patients were unilateral reconstruction and 4 were bilateral. The Ryan procedure resulted in an inter-IMF discrepancy reduction of 39% and a breast projection increase of 18%. Average length of follow-up was 2.82 ± 0.75 years. One patient required a secondary IMF revision. The majority of survey respondents felt that the IMF and IMF symmetry were improved or stable postoperatively. The Ryan procedure seems to be a reliable and durable technique for IMF reconstruction with increased projection, decreased IMF discrepancy, and increased symmetry. Additionally, 3D imaging provides a useful approach in the assessment of breast reconstruction outcomes, adding quantitative outcomes measures to its evaluation.
