“…For flaps whose radioanatomy has not been previously analyzed (the ALNW and MTF), the key measurements were based on the operative techniques used to raise them. 4,6,8,9,11,13,19,25 Images were analyzed using the Medical Imaging Interaction Toolkit (version 2015.05; German Cancer Research Center, Heidelberg, Germany) and Slicer (version 4.4.0; Harvard University, Cambridge, MA) to determine the dimensions of SSBDs and endonasal flaps. Statistical analysis of the results was carried out using Microsoft Excel 2013 (version 15.0.4737.1003; Microsoft, Redmond, WA), iNZight (version 2.5; The University of Auckland, Auckland, New Zealand), and GraphPad Prism for Windows (version 6.01; GraphPad, San Diego, CA).…”
