Estudo comparativo entre as esferas de silicone gelatinosas e rígidas em cavidade eviscerada de coelho

Abstract: INTRODUÇÃOAs técnicas de enucleação e evisceração geralmente requerem reposição de conteúdo orbitário para minimizar o déficit de volume e, consequentemente, assimetrias e prejuízos estéticos (1)(2)(3) . Para repor o volume orbitário perdido, podem ser utilizados materiais autólo-gos, homólogos, heterólogos ou aloplásticos.Materiais aloplásticos são os mais utilizados, podendo-se implantar esferas confeccionadas com diversas substâncias, como polimetilmetacrilato, silicone, hidroxiapatita sintética, polietilen… Show more

“…Tissue infiltration can be observed in micropores bigger than 5µm, as observed in the evaluation of the national hydroxyapatite, which permitted the migration of fibrovascular tissue to the interior of the sphere in micropores of 5-10 µm (Jordan et al, 2000). It was observed that even in the absence of interlinked pores, the presence of channels for interconnection made the infiltration of host tissue possible, which contributed to the absence of complications reported by other studies, such as ocular discharge, pain, exposure, infection, dehiscence of the sutures and extrusion (Molteno et al, 1973;Toft et al, 2010;Kanamura et al, 2012). Mixed inflammation with accumulation of lymphocytes, histiocytes and granulocytes after more than six months since the placing of the implant was verified in human patients who received implants of hydroxyapatite and porous polyethylene (Toft et al, 2010).…”

“…With the exception of the conical synthetic hydroxyapatite implants (Kundu et al, 2005), which were perforated to permit the suturing of the extra-ocular muscles, there are no references in the literature on the use of implants in the form of spheres in the orbital cavity provided with large channels for interconnection, with the objective of permitting the infiltration of fibrovascular tissue, with exception of the recent study using perforated acrylic orbital implants in eviscerated rabbits (Miyashita et al, 2013).…”

“…There is only one experimental study about cohesive silicone implant in anophthalmic socket reporting good results and encouraging the use of this type of implants. 7 To our knowledge, there are no studies comparing different surface coatings on cohesive silicone gel implants placed in the orbital cavity.…”
