Operation time change after cases accumulation. (A) Following case accumulations over the past decade, various minimal access breast surgeries decreased operation time gradually. (B) The operation time of unilateral nipple sparing mastectomy with immediate gel implant breast reconstruction for conventional NSM (C-NSM), endoscopic assisted NSM (E-NSM), and robotic assisted NSM (R-NSM). The operation of each procedure performed was plotted in a timeline sequence, and all the operation time of three different types of NSM decreased and gradually merged together. C, C-NSM; E, E-NEM; R, R-NSM.
