Modification of the cartilaginous framework for autologous ear reconstruction: Construction of a stable complete ring framework with grander highs and lows

Shape Optimization of Costal Cartilage Framework Fabrication Based on Finite Element Analysis for Reducing Incidence of Auricular Reconstruction Complications

“…Therefore, we believe that it is worthy information regarding the skin’s mechanical behavior and deformation properties during the suction process, which is critical for improving the clinical decision to decrease the focused stress and the rates of skin problems. Abundant research studies indicated that the stable support underneath the skin could disperse the region with high stress and thus decrease the risk of skin necrosis ( Wilkes et al, 2012 ; Tamura et al, 2014 ; Mazeed et al, 2021 ) but not reported in the auricular reconstruction field. Zhang et al proposed a novel concept of three-dimensional mechanical equilibrium cartilage scaffold, which could obtain a more stable structure by achieving lower rates of skin complications ( Zhang et al, 2019 ).…”

“…Therefore, it is feasible to develop an FE-based shape optimization to determine the mechanical behavior of the skin and the optimum auricular structure. Based on preceding studies, several efficacious approaches had been discovered that includes alteration of suture materials ( Sakamoto et al, 2012 ), stability of ear framework ( Mazeed et al, 2021 ), and decrease in the span using the drain to reduce skin stress and necrosis ( Bangun et al, 2010 ). However, these methods mainly relied on the clinical experiences of surgeons, which is a lack of related mechanical study to elucidate the relationship among the ear framework structure, suture, and skin necrosis.…”
