This paper describes a novel approach to treat migrated orbital implants post socket surgery. Implant migration may hinder the final aesthetic outcome of a custom ocular prosthesis. Once an implant migrates within the orbit there tends to be fibrosis around the implant. This fibrosis does not allow for centeration of the implant during repeat surgery. Hence treatment of a migrated implant traditionally involves implant removal with dermis fat grafting. Dermis fat graft though an option, needs a second site surgery that may be unacceptable to many patients. Also the rate of graft necrosis is as high as 40%. This paper describes a technique to create a custom orbital implant that allows recenteration of the migrated implant centrally, using 3-dimension (3D) printing and rapid prototyping to construct the patients affected orbit. This orbit is used as a mould to create the custom orbital implant that aids in volume augmentation as well as recenteration of the migrated orbital implant.
本文描述了一种治疗牙槽窝手术后移位眼眶植入物的新方法。植入物移位可能会妨碍定制眼假体的最终美学效果。一旦植入物在眼眶内移位,植入物周围往往会出现纤维化。这种纤维化使得在再次手术时植入物无法居中。因此,传统上治疗移位植入物的方法是取出植入物并进行真皮脂肪移植。真皮脂肪移植虽然是一种选择,但需要在第二个部位进行手术,这可能是许多患者无法接受的。此外,移植坏死率高达40%。本文描述了一种技术,即使用三维(3D)打印和快速成型技术构建患者受影响的眼眶,制作定制眼眶植入物,使移位的植入物重新居中。这个眼眶被用作模具来制作定制眼眶植入物,有助于增加体积以及使移位的眼眶植入物重新居中。
