Orbital cysts are rare developmental anomalies that can occur in microphthalmic and anophthalmic patients. Such cysts can promote orbital growth and subsequently markedly increase the size of the orbit, which is commonly underdeveloped in these patients. Cyst removal is therefore generally dissuaded (at least) in the first 5 years.
A 6-year-old boy with a microphthalmos and a cyst developed protrusion of his prosthetic eye and a swelling of the lower eyelid. MRI showed a large cyst causing distortion of the right orbit. Due to the expansive orbital growth and subsequent misfitting of the prosthesis, cystectomy and orbital floor reconstruction was performed using 3D technology.
3D imaging and printing enables exact delineation of orbital cysts and the adjacent bony structures. Furthermore it offers the possibility to plan an individual surgical approach and to design and fabricate a custom fit orbital floor implant.
眼眶囊肿是罕见的发育异常,可发生于小眼症和无眼症患者。此类囊肿可促进眼眶生长,随后显著增加眼眶大小,而这些患者的眼眶通常发育不全。因此,一般不建议(至少在)头5年内进行囊肿切除。
一名患有小眼症和囊肿的6岁男孩,其义眼出现突出,下眼睑肿胀。磁共振成像显示一个大囊肿导致右眼眶变形。由于眼眶的扩张性生长以及随后义眼的不匹配,采用3D技术进行了囊肿切除术和眶底重建。
3D成像和打印能够精确描绘眼眶囊肿及相邻的骨结构。此外,它还提供了规划个体化手术方案以及设计和制造定制适合的眶底植入物的可能性。
