“…Since the subcutaneous area is vascularized, the implanted hydrogels or other biomaterials are immune privileged, so a mild reaction to foreign moieties is to be expected [176]. Bare polyethylene hydrogels have been proven to not exhibit cytotoxicity in murine models even after 60 days when injected subcutaneously [184]. Similar results regarding biocompatibility were obtained with ellagic acid hydrogels [185], nano-patterned poly-acrylamide hydrogels [186] chitosan and gelatin hydrogels [187,188], alginate [189] and pectin [190].…”

“…Alguns estudos analisaram implantes de materiais gelatinosos, como o polietileno gel injetado no subcutâneo de cobaias (6,7) e esferas de polietileno gel, colocados em cavidades anoftálmicas de coe lhos (4) , ambos com boa resposta tecidual. Implantes não rígidos, feitos de silicone no estado gelatinoso já foram largamente utilizados em outros locais do corpo humano, como os implantes mamários, em mastoplastias de aumento (8) .…”

“…Sua forma em gel foi pesquisada baseados na hipótese de que o contato do implante rígido com a prótese externa favoreceria a isquemia tecidual, levando a deiscência que pode resultar, em última análise, nas extrusões (SCHELLINI et al, 2008).…”
